Storage Industry Hit by Thai Flooding

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

The storage industry is getting hit again. Just a few months after the Japan earthquake affected flash storage manufacturing, the devastating Thai floods show signs of affecting hard disk drive manufacturing down the road.

Of course, the effect on the industry is minor compared to the effect on the Thai people themselves, where so far nearly 400 have died in what is said to be the worst flooding in 50 years. But as the worst of the flooding appears to be over, the country is beginning to examine the economic effects — which could end up being nearly as damaging as the economic unpleasantness a few years back, according to component research firm iSuppli:

“As a result of the flooding, the HDD industry in the fourth quarter will suffer its worst downturn in three years. HDD shipments in the fourth quarter will decline to 125 million units, down 27.7 percent from 173 million in the third quarter, as presented in the figure attached. The drop is the largest sequential decrease on a percentage basis since the fourth quarter of 2008 when shipments fell 21.2 percent during the worst point of the last electronics downturn. IHS estimates that 30 percent of HDD production in the fourth quarter this year will be lost because of the disaster. This will result in a significant shortage of HDDs. Because of the shortage, HDD inventories will be depleted and will cause average HDD pricing to rise by 10 percent in the fourth quarter compared to the third.”

Thailand is the world’s second-largest provider of hard disk drives, after China, and has manufacturing facilities for Western Digital and Toshiba, iSuppli goes on to say. And while Seagate has an operating plant in the area, it may face a shortage of parts, according to Reuters.

In fact, the effects are likely to be so devastating that they will change Western Digital’s status in disk drive manufacturing, iSuppli says. “Western Digital is likely to lose its status as the world’s largest shipper of HDDs, with its rank expected to fall two positions to third in the fourth quarter, down from first place in the third quarter. Toshiba’s rank could fall to fourth place, down from fifth.”

Slowdowns are particularly likely to occur in notebook PCs in the first quarter of next year, iSuppli said, because some components are stockpiled and the market will likely adjust to use different sources by the second quarter. Several notebook providers, including Compai, said their quarterly earnings might be lower as a result of lower shipments due to the lack of disk drives. (Though, if the Japanese flash storage manufacturers recover, perhaps this will push a faster-than-expected switch to flash storage in notebooks?)

Part of the blame goes to increasingly tight “just in time” manufacturing supply chains, where parts are shipped essentially as they’re needed rather than being warehoused, Reuters noted.

Iain Bowles of ProBrand had even more dire predictions, of price increases of up to 25 percent. In fact, shortages from the Thai natural disaster could be worse than the Japan earthquake because stockpiles are smaller, he said. Moreover, he believes it could extend into the second quarter of next year as well, and that the recovery is likely to be slower than in Japan.

You’ve Virtualized Your Server. Now, How About Your Phone?

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

In what some are calling “schizophonia,” VMware — famous for virtualizing servers — is now moving to virtualizing phones, making agreements with mobile providers such as Verizon and Telefonica to implement the mobile virtualization software it announced earlier this summer.

What would be the advantage of such a system? As opposed to virtualizing servers — which is typically done to make the server denser and require less room, power, and cooling — virtualizing a phone means that a person could have a single phone both for work and for personal use, without the employer being as concerned about security breaches and without the employee having to juggle two phones.

For now, the VMware Horizon software runs only on Android phones; oddly, Microsoft — which is adding its Hyper-V hypervisor to Windows 8 — doesn’t appear to have announced virtualization for its Windows phones yet.

This isn’t the first such announcement — VMware made an agreement with LG for its phones in December, as well as a similar agreement with Samsung, and there’s talk about smartphones powered by chips offering virtualization ever since the chips came out– but now virtualization can be a part of the mobile service as well as the phone itself.

VMware is also reportedly working with Google to put virtualization into the Android operating system itself. Such a development could make it much more likely that Android phones would be more desirable than the iPhone — which doesn’t give third-party developers the same level of access that Android phones have — though VMware has made it clear that it’s willing to work with Apple as well.

“One tap of the screen, for example, effectively changes the entire look and feel of a smartphone with virtualization,” writes Kevin Tofel of GigaOM. “When in “enterprise mode”, the phone signs into an employee account and only shows workplace apps, contacts and data. Another tap can pause the virtual machine for work and revert back to the native, personal handset.”

Long term, this could go even further, writes Timothy Prickett Morgan of the Register UK.

“[A]t some point, it is reasonable to assume there will be a phone with as many numbers and personalities as you have members of the family, and people will grab a phone off the sideboard table where you pile up the junk mail just like you pick an umbrella out of the stand right next to the table when it is raining. The first person to leave every morning will get the best phone, but they will be interchangeable.”

Dell, EMC are Splitsville

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

We’ve all seen it happen. A couple gets together and things seem great for a while. Then they start pulling apart. They might even start seeing other people. By the time the split finally comes, it’s not only anticlimactic but almost a relief.

That’s probably how it feels for EMC now that Dell has finally ended a ten-year relationship (two years early) where Dell sold EMC storage hardware, as Dell increasingly became a storage player in its own right.

“We’ve grown apart,” Dell said. “I needed to feel like I could be my own person.”

Well, okay, not really. “Over the past few years, Dell has grown to become a robust storage technology provider with differentiated capabilities across several product families, including Compellent, EqualLogic, PowerVault, and Dell / EMC,” is the way the company actually put it, on what used to be the Dell/EMC product page.

Dell bought EqualLogic in 2007, and Compellent in 2010 — spending a total of $2 billion on storage acquisitions — after starting its partnership with EMC in 2001. Other acquisitions included Exanet for scale-out NAS technology and Ocarina for data compression and optimization, as well as making its own DX6000 object storage hardware, partnering with Caringo for the software. The company also reportedly said that its own storage properties provide almost 80 percent of its storage revenues and 90 percent of its profits in the second quarter of this year.

Dell also said it planned to spend an additional $1 billion this fiscal year to strengthen its storage offerings.

Dell promised it would continue to be a good parent for the children — that is, that it would continue to support the EMC hardware. However, when people want to upgrade that hardware, they will be offered Dell storage products.

EMC asked that people respect its privacy during this difficult time. Well, not really. Actually, it had no comment.

Survey: Bigger Companies Pay More Attention to E-Discovery

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

Another day, another e-discovery survey. Enterprise Strategy Group has released its report, e-Discovery Market Trends: A View from the Legal Department.

The results aren’t so very different from Symantec’s survey last month — though, frankly, the ESG survey isn’t as statistically rigorous; it surveyed only 48 general counsel.

The following are some of the conclusions ESG came up with.

  • E-discovery pain is most acute for high-revenue, serial-litigant enterprise companies, particularly by large organizations with revenue exceeding US$1B, serial litigation demands, and high legal expenses.
  • Corporate counsel leads internal e-discovery decision making, but process management is interdisciplinary. Internally, corporate counsel bears the responsibility for litigation response, even as other players are involved in execution. Externally, corporate counsel is wielding growing influence with law firms in choosing third-party providers.
  • Most organizations are not tracking e-discovery spending, but organizations with at least US$1B in annual revenue were more than three times as likely as their counterparts earning less than US$1B annually to track expenses related to e-discovery activities including document review and technology investments.
  • They also don’t track the accuracy and efficiency of document review. Less than one-third of respondents have ever tracked the productivity or efficiency of document review. Half of respondents with less than US$1B in annual revenue don’t monitor these processes — with internal or external resources – and have no plans to do so.
  • Enterprise litigants are exerting influence (and pricing pressure) on law firms. Corporate counsel increasingly suggest specific tools and technical methods to their law firms. However, they are even more likely to simply request more cost-driven measures such as itemization or alternative fee arrangements.
  • Corporate information governance and litigation readiness are a priority, but not yet a widespread reality. Top internal priorities include defensible deletion and data mapping of enterprise ESI inventory for better litigation preparedness.
  • Enterprises use diverse technologies for litigation response. E-mail archives and content management systems top current usage for preservation and collection. Future purchasing plans are dominated by content management, e-discovery platforms, and enterprise search.
  • Challenges to collection and preservation persist, including collecting data from endpoint devices, over-collection, and supporting staffing requirements and short timelines for conducting litigation response. Diverse data formats and locations present a moving target for e-discovery as newer data sources like SharePoint or the cloud emerge and older data is rendered inaccessible in legacy applications or backups.
  • Corporate litigants are complying with court standards for supervising collections and notifying custodians of legal hold, though these are largely still through manual methods. They are less vigilant in documenting chain of custody or proving they’ve physically prevented spoliation in their systems.
So, nothing too radical or surprising, but useful validation

IBM Takes Over Troubled National Archive Project

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

IBM announced this week that it had been selected for a 10-year $240 million operations and maintenance contract with the National Archives and Records Administration, but there’s a lot more to the story than that. IBM is actually taking over from Lockheed Martin after several years of a project that’s fallen behind schedule and over budget.

The project is to manage the Electronic Records Archive, and is intended to ensure the transparency of government documents, allowing broader citizen access to public records. The project was started in 2001 to preserve and provide both internal and external electronic access to the records. But it had its problems, noted Elizabeth Montalbano of Information Week:

NARA began working on the digital archive in 2001 and in 2005 awarded Lockheed Martin a $317 million contract to develop it. However, the project has not been without its troubles along the way. Earlier this year a report by the Government Accountability Office found that the project likely will cost $1.2 billion to $1.4 billion, exceeding its estimated cost of $995 million by 21% to 41%. The report cited poor project management as the reason for the soaring costs.”

In fact, due to its inclusion on in the GAO report, NARA cut some of the functionality from the project in February and decided to do no new development past September, which is what enabled IBM to get an O&M contract after the contract with Lockheed ended on September 30, the end of the federal fiscal year — about a year earlier than planned. Originally, NARA had had a sixth option year on the Lockheed Martin deal for development, and a seventh year for operations and maintenance, FederalNewsRadio.com reported.

According to the IT Dashboard, NARA has spent $383 million, which is $5.6 million more than it planned, as of Aug. 3, noted FederalNewsRadio.com. To add insult to injury, a session with the Office of Management and Budget (OMB) showed that, after five years of development, few agencies were using the system’s functionalities, resulting in a reduction of its budget by $215.5 million and being required  to deliver functionality faster, to increase the usage of the system from 80 terabytes to 122 terabytes, and to move to a modular development approach.

The project was officially launched in April, particularly with what were called three “pathfinder” agencies, so-called because of the amount of requests those agencies received: Justice, Health & Human Services, and State. 27 other agencies were supposed to start bringing their records online by the end of November, while independent agencies were supposed to start bringing their records online in July, FederalNewsRadio.com noted.

But IBM’s role will be more than just maintenance and operations. An agency spokesman said that IBM would be adding functionality to the system through a series of work orders and other enhancements — in particular, improving the search system, the spokesman said.

Ho Hum. EMC CEO Announces Plans to Step Down.

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

One of the most interesting aspects about the announcement this week that EMC CEO Joe Tucci was planning to step down by the end of next year was how blase’ everyone was about it. He wasn’t fired. He isn’t dying (so far as we know, existential aren’t-we-all-dying questions aside). He’s not part of a parade of CEOs who have come and gone. It’s just, hey, next year I’ll be 65, time to go.

Part of this, of course, is in contrast to other CEO departures this year where people were fired, dying, part of a parade, and so on. Compared to, say, HP, Apple, or HP again, respectively, the notion of a guy who become CEO ten years ago, did his job, and is leaving at a normal retirement age seems almost quaint.

Part of this, too, is the company culture. EMC may be one of the biggest storage companies out there, but it’s not a rock star consumer-driven company the way Apple is. It’s normal there for the succession to be a relatively gentlemanly affair. Tucci did his time before he became CEO, serving under the previous CEO as executive chair for two years, and will serve as executive chair for the next EMC CEO, whomever he may be (nobody’s suggesting that the next CEO of EMC might be female).

Part of it is also the lack of drama around the succession. Yes, it’s true, nobody was named as the next CEO yet, and of course there’s always the potential of a bunch of little storage Borgias backstabbing and poisoning each other. But EMC is the sort of company where people use the term “deep bench” a lot. Most articles around Tucci’s announcement (which he made to the Wall Street Journal, naturally) named at least four potential successors, any one of whom would be qualified to run the company. Nobody’s wringing their hands suggesting that EMC will have to go outside the company to find someone qualified.

Part of it is that even with his more than one-year notice, this isn’t a surprise; Tucci started talking about succession a year ago — with the same four guys as potential successors. (And nobody’s trying to out any of them, as people are doing with Apple’s Tim Cook.)

The biggest problem cited in the very few articles around the announcement — there’s more articles about the fact that Tucci is going to be speaking at an Oracle conference next week than there are about his retirement — is whether he should continue to stay after stepping down, which the Wall Street Journal started by including EMC in a list of companies where CEOs stay on as executive chairs.

The Motley Fool is trying to beat the drum for a shareholder revolt against the fact that the next EMC CEO will be continue to be both CEO and chairman, but they’re pretty alone in that.

At this point, about all we can do is wait to see who gets appointed the next EMC CEO — and there’s no timetable for that yet.

Apple, Dropbox Added to EFF Privacy Coalition

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

The Electronic Frontier Foundation has announced that two vendors, Apple and Dropbox, have signed a pledge to help support its Digital Due Process initiative, which calls for a rewrite of the Electronic Communications Privacy Act to better protect user data.

The initiative has more than 50 members, including Amazon, AT&T, Facebook, Google, Microsoft, Twitter, and Yahoo!, which were called out in April as being major computer vendors that should support the proposal. Steps included in the proposal include telling users about data demands, being transparent about government requests, fighting for user privacy in the courts, and fighting for user privacy in Congress. Companies received from one to four stars (including partial stars) depending on how well they are implementing each of these policies.

Dropbox was a particularly interesting addition, because the company has been criticized about its policies regarding protecting user data in its cloud storage service.

Other vendors pf the 13 that the EFF called out in April that have not yet responded include Comcast, Myspace, Skype (since purchased by Microsoft, which is a member), and Verizon.

Organizations such as the American Civil Liberties Union and the Center for Democracy & Technology are also members.

Information Retention Saves Legal Costs, But Many Don’t Do it

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

It’s typically a good idea to take vendor surveys with a grain of salt; they tend to be slanted and unscientific. Not so with Symantec; they have actual scientific surveys with margins of error and everything.

Not to say, of course, that they’re completely unbiased; recall in this case that Symantec purchased Clearwell earlier this year in an attempt to improve its ranking after a recent Gartner Magic Quadrant on eDiscovery vendors.

That said, its Information Retention and eDiscovery Survey has some interesting points to be made — not the least of which is actual evidence from users that implementing an information retention policy saves money.

  • Respondents using best practices reported a 64% faster response time with a 2.3 times higher success rate when responding to eDiscovery requests.
  • They were 78% less likely to be sanctioned by the courts and 47% less likely to find themselves in a compromised legal position.
  • They were also 20% less likely to have fines levied against them. In addition, they were 45% less likely to disclose too much information.
That said, many respondents indicated that they had not yet implemented an information retention plan.
  • Nearly half of respondents do not have an information retention plan in place.
  • 30% are only discussing how to do so.
  • 14% have no plan to do so.
  • When asked why they don’t have information retention programs, respondents indicated the top reasons are: lack of need (41%), too costly (38%); nobody has been chartered with that responsibility (27%); don’t have time (26%); and lack of expertise (21%).

The part about “too costly” is particularly telling in light of the results.

Respondents who said they’d been asked to respond to a legal, compliance or regulatory request for electronically stored information reported the following results:

  • Completely failed to fulfill the request 10%
  • Partially failed to fulfill the request 10%
  • Successfully fulfilled the request, but more slowly than the requestor would like 25%
  • Successfully fulfilled the request in a timeframe that is acceptable to the requestor 35%
How this correlated with whether organizations had an information retention strategy in place, Symantec didn’t say.
Finally, in situations where an organization did not successfully fulfill the request in an acceptable timeframe, respondents reported the following results:
  • Damage to Enterprise reputation or embarrassment 42%
  • Fines 41%
  • Compromised legal position 38%
  • Sanctions by courts 28%
  • Hampered our ability to make decisions in a timely fashion 26%
  • Raised our profile as a potential litigation target 25%
Again, not clear how these correlated with the different types of organizations, but useful to have some specific information about results and sanctions.

Pigeons, Station Wagons, Blu-ray, and Data Transfer

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

XKCD on<br /> File Transfers

Sound familiar?

The thing is, it’s true. Even though Internet speeds continue to increase, the amount of data we want to transmit continues to increase, too.

Which is why the various Internet denizens have developed….workarounds for large file transfers, which also provides the opportunity for the wonderful Internet pastime of geekly arguing.

Which brings us to station wagons, pigeons, and Blu-ray.

The canonical statement, by Andrew Tannenbaum in his 1996 book Computer Networks, is basically “Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.” And ever since then, there have been numerous websites devoted to how-many-angels-can-dance-on-the-head-of-a-pin discussions about just what that bandwidth would be.

You can tell how old the websites are based on what figures they use for comparable Internet bandwidth, the size of a magnetic tape, and so on. The Wikipedia entry for “Sneakernet” appears to have the most up-to-date calculations.

(The actual calculation using today’s technologies is left as an exercise for the reader.)

The Internet being the Internet, the calculations have been extended, ranging from petabytes in a sailboat to Blu-ray discs in a 747 (which, as it turns out, would actually be too heavy for a 747 to carry), to, more mundanely, the number of SD cards that fit into a Fed Ex box — as well as the bandwidth of a Netflix movie shipment through the mail.

And then there’s the pigeons.

Really truly, carrier pigeons have been used for a remarkable amount of data transfer in history — not just short messages, and aerial photography predating satellites, but things like blueprints from military installations in the U.S.

In fact, in 1982, Computerworld ran an article about how Lockheed Missile & Space Co. used pigeons to carry microfilm copies of blueprints to a research facility in Santa Cruz, because it was cheaper than printing out and transporting hard copies. And if you have $100 per half hour for someone to dig it up, you can apparently get a copy of Dan Rather introducing a story about it on CBS News.

Consequently, not one but two April Fool’s Internet protocols were developed — Transmission of IP Datagrams on Avian Carriers, and Transmission of IP Datagrams on Avian Carriers with Quality Control — for transmitting Internet data by carrier pigeon. The first one was even demonstrated, and while the experiment left something to be desired, Wikipedia points out that “during the last 20 years, the information density of storage media and thus the bandwidth of an Avian Carrier has increased 3 times faster than the bandwidth of the Internet.”

That’s not all. In various remote areas, such as rural U.K., Australia, and parts of South Africa, people have used carrier pigeons to demonstrate that they’re faster than what passes for high-speed Internet there.

The point is this: No matter how fat a pipe you have to the Internet, at some given amount of data, it’s going to be faster, cheaper, or both to use some manual method to ship data on some storage medium. It makes sense for you to do a back-of-the-envelope calculation to figure out where the data boundaries are for different mediums and different shipping methods, and update them as technology changes.

Are You Ready for the New LTO 6 Tape Standard?

Sharon Fisher Sharon Fisher Profile: Sharon Fisher

Tape’s not dead. Really. Products supporting the Linear Tape Open (LTO) 5 specification just began shipping this year, but already vendors are starting to make noises about LTO 6, for which there isn’t even an availability date announced yet.

In sort of the tape storage equivalent to Moore’s Law, a consortium of three vendors — Hewlett Packard, IBM, and Quantum, known as the Technology Provider Companies (TPC) — get together every few years and decide upon specifications for tape cartridges with a steady increase in speed and capacity. This helps keep users convinced that there’s still a future for tape.

For example, the specifications for LTO 5 (as well as LTO 6) were announced in December 2004, but it took until January 2010 before licenses for the LTO 5 specification was available, and products supporting it started to be available in the second quarter of that year.

Similarly, the LTO TPCs announced in June of this year that licenses for the LTO 6 specification were available. By extrapolation, one can assume that LTO 6 products could be announced any day.

LTO 6 is defined as having a capacity of 8 TB with a data transfer speed of up to 525 MB/s, assuming a 2.5:1 compression. This is in comparison to LTO 5, which has a capacity of 3 TB with a data transfer speed of up to 280 MB/s, assuming a 2.5:1 compression.

Lest people get fidgety about the future of tape after that, the LTO TPC announced this spring the next two generations, LTO 7 and LTO 8, with compressed capacities of 16 TB and 32 TB and data transfers speeds of 788 MB/s and 1180 MB/s, respectively. As with LTO 6, no dates were announced, but one might expect each will come out about two to three years in succession.

The thing to remember, also, is that each LTO generation can typically only read two generations before it — meaning users needs to either rewrite their tape library every few years or keep a bunch of old LTO machines around. “By the time LTO 8 is released, organizations will need, at a minimum, LTO 3 drives to read LTO 1 through LTO 3 cartridges; LTO 6 drives to read LTO 4 through LTO 6 cartridges; and LTO  8 drives to read the LTO 7 and LTO 8 cartridges,” wrote Graeme Elliott earlier this year.
