Cloud can be game-changer for DR



Posted by: Dave Raffo
cloud DR, instant recover

Disaster recovery in the cloud is improving by the day.

At least three vendors upgraded services in the past week, concentrating on faster recovery for small enterprises and SMBs.

EVault added a four-hour option for its EVault Cloud Disaster Recovery Service (EVault CDR) to go with its previous 24- and 48-hour SLA options. EVault is promising to have applications on the four-hour SLA up and running within that window.

EVault president Terry Cunningham said four hours is the magic number to gain critical mass for his company’s cloud DR service because it opens the door for heavily regulated businesses that cannot stand long outages for critical systems.

“This opens up the whole market for us,” Cunningham said. “One customer said, ‘When you deliver four hours, you get all our business.’”

He said the technology is available for more granular snapshots and shorter backup windows, making the four-hour SLA possible. The EVault service includes a minimum of one DR test per year, and customers can choose different SLAs for different applications. They can use the four-hour recovery for critical apps, and the longer recovery options for others. He declined to give exact pricing because it is set by EVault’s distribution partners, but the four-year SLA costs twice as much as the 24-hour option.

EVault, owned by Seagate, changed its name back from i365 to Evault last December.

Not everyone is so impressed with four-hour recovery. QuorumLabs promises instant recovery with its new Hybrid Cloud Disaster Recovery service that lets customers install one of the vendor’s onQ appliances on site and replicate to another appliance at a QuorumLabs’ off-site data center.

QuorumLabs’ hybrid service keeps up-to-day virtual clones of critical systems that run on the appliance or in the cloud. The service builds new recovery nodes continuously and the vendor says the cloud appliance can take over for failed servers with one mouse click.

“Compared to our offering – ready in minutes, tested daily – [four-hour recovery] is like a pizza delivery guaranteed to arrive sometime in the next several days,” QuorumLabs CEO Larry Lang said.

QuorumLabs already has customers who set up DR by installing appliances at two locations, but not all of its customers have a second site. “If something were to happen, we bring up an exact copy of that server in your cloud,” Lang said. “Users just redirect their client to the cloud. Literally in an hour they can have something up and running.”

QuorumLabs’ service is priced by the number of servers and the amount of data protected. Lang said a customer with 10 servers and 3 TB would pay about $20,000 per year.

Zetta also upgrade its cloud backup and DR service. Zetta’s DataProtect 3.0 uses the ZettaMirror software agent on the customer site and synchronizes data to one of the vendor’s cloud data centers. The latest version adds support for Apple desktops and laptops as well as Microsoft SQL Server and Windows system state, improves performance with compression and a metadata cache and allows snapshots of synched data.

EVault’s Cunningham said the cloud’s role in data protection has made the business more competitive. He said customers are re-evaluating their backup and DR processes and find it easier to switch vendors.

“It used to be that when you made a backup deal, it was for life,” he said. “We used to sell you some software and say ‘Good luck with that, hope it works out.’ Today it’s a service. We have to earn the business every month.

“The customer has more options for switching now. There are some technical challenges, but you can do it. If vendors screw up, they lose the customers.”

Atlantis unveils ILIO for Citrix XenApp

Atlantis Computing, Citrix XenApp

Atlantis Computing today launched Atlantis ILIO for Citrix XenApp, which helps reduce I/O and latency problems often associated with application virtualization. The product runs on a VMware vSphere hypervisor and is aimed at customers planning to virtualize XenApp 6.5 with Windows Server 2008 R2.

The new product is built on the same codebase as Atlantis ILIO for VDI but this new version is targeted at customers deploying application virtualization. Atlantis ILIO helps eliminate I/O bottleneck because it processes I/O locally within the hypervisor’s memory. It does inline deduplication to reduce the amount of data hitting the NAS or SAN.

Atlantis ILIO for XenApp is a virtual machine that is deployed on each XenApp server and creates an NFS datastore that acts as the storage for the XenApp VMs running on Windows Server 2008 R2.

“We correct the problem the way we do with VDI,” said Seth Knox, Atlantis’ director of marketing. “All duplicate storage traffic is generally eliminated before it’s sent to the storage. “

Torsten Volk, senior analyst for Enterprise Management Associates, said Atlantis ILIO for XenApp helps optimize performance because it sequentializes and dedupes the I/O traffic. He also said support for XenApp will broaden Atlantis’ market substantially.

“There is a much larger customer base for Citrix XenApp compared to the VDI market and only minimal changes to the Atlantis ILIO codebase were required to accommodate XenApp,” Volk said. “Not many are using VDI because the ROI is still unclear, but XenApp is a well-liked and vastly adopted platform that has provided tremendous customer value for over a decade.”

Knox said there are customers who ask for both products, but agreed there will be more demand for ILIO for XenApp.

“There is a much larger install base of people using XenApp,” Knox said. “Many of our customers use both VDI and XenApp, so they asked us to do a version for XenApp.”

Startup Basho heads for the cloud



Posted by: Dave Raffo
amazon S3, basho, Cloud storage, object storage, riak CS

Basho today launched an object storage application for service providers and large organizations who want to build Amazon S3-type storage clouds.

According to the vendor, Riak CS lets customers store and retrieve content up to 5 GB per object, is compatible with the Amazon S3 API, has multi-tenancy features, and reports on per-tenant usage data and statistics on network I/O. Pricing for Riak CS starts at $10,000 per hardware node, which comes to about 40 cents per GB for a 24 TB node.

Riak CS is Basho’s second software application. Its Riak NoSQL database is based on principles outlined in the 2007 Amazon Dynamo white paper. While Riak is an open source application, Riak CS is not. Basho added multi-tenancy, S3 API compatibility, large object support and per tenant usage, billing and metering to Riak CS to make it a cloud application.

“We look at ourselves as an arms dealer of Amazon principles [outlined in the 2007 Amazon Dynamo distributed white paper],” Basho CMO Bobby Patrick said. “Riak CS is for large service providers looking for scalability and tenancy, and also large companies that want S3 without AWS [Amazon Web Services]. This is S3-compatible, but for a private cloud.”

He said several large multinational companies are evaluating Riak CS as a method of keeping important data in-house behind a firewall.

Riak CS is built to run on commodity hardware. Patrick said it will compete mainly with OpenStack Swift object storage, but it will also come into competition from EMC’s Atmos and software from smaller vendors such as Scality Ring and Gemini Mobile Cloudian.

“Any hosting company, any telecom company, any infrastructure-as-a-service company, is going to have to evolve from expensive shared storage to cloud storage for economic scale benefits,” Patrick said. “A new architecture is needed for that. They need to do it on cheap commodity hardware and in a way they can manage it.”

DataDirect adds ‘mini’ array for big data



Posted by: Dave Raffo
big data storage, DataDirect Networks

DataDirect Networks (DDN) launched two storage systems for people who want to start small in their approach to “big data.”

DDN is known for storage systems that deliver extreme performance and capacity but also carry large price tags. To try to broaden its market, the vendor this week introduced lower-priced arrays, including one that starts at $100,000 during introduction pricing that runs until the end of June.

“We found there are a lot of customers and prospective customers looking to start with DataDirect at a lower price and form factor while benefitting from scalability,” DDN marketing VP Jeff Denworth said.

The new systems are the DDN SFA10K-M and SFA10K-ME. The 10K-M scales to 720 TB with InfiniBand or Fibre Channel networking and  with SAS, SATA or solid-state drives (SSDs). Customers can upgrade the 20u system to the larger SFA10K-X.

The SFA10K-ME is the same hardware as the 10K-M, but can be bundled with DDN’s GridScaler or ExaScaler parallel file systems. The promotional $100,000 price is for a SFA10K-M with eight InfiniBand ports, a 60-slot disk enclosure, and 16 GB of mirrored cache.

DDN says its new systems cost 40% less with a 57% smaller form factor than its larger SFA storage arrays.

“The news of dramatically smaller footprints and reduced-cost SFA entry points is not what we’re used to hearing from a company that is accustomed to extending the scalability and performance envelopes of big data applications,” Taneja Group analyst Jeff Byrne wrote of DDN’s new systems in a blog on the Taneja web site.

Denworth said the new systems fill a gap in DDN’s product line between the S2A6620 midrange storage for media/entertainment and high performance computing and the SFA10K-X high-bandwidth petabyte capacity platforms.

“Customers can grow the system as requirements and budget dictates,” Denworth said.

SFA10K-M customers can upgrade to DDN 10K or SFA12K systems, but they would have to take the systems offline. There are no non-disruptive upgrades.

Why storage has a short lifespan



Posted by: Randy Kerns
data migration, storage system lifespan

How long does an organization keep a storage system? That depends on a few things. For disk systems, there are several driving factors:

• The length of the warranty period and the cost of a service contract after the warranty period.
• The depreciation period on the system.

These factors usually lead organizations to plan on four or five years before replacing their disk storage system.

For tape systems that use LTO technology, IT generally looks at how long new tape drives can be purchased to read their existing tapes. Each new generation of LTO tape drive can read tapes created on the two previous generations. The period for replacement of tapes (meaning migration of the data on those tapes) to a new generation is based on how long it takes for LTO tape generations to be released. It usually takes around seven years to get to the generation that cannot read the previous two generations.

When I speak with contemporaries of mine in other technology disciplines and reflect on the limited lifespans of storage systems, they find it hard to believe how short the lifespan is for storage systems. They usually say that, with the amount of investment made, a storage system should be kept for at least 10 years.

They understand the shorter lifespan better when I explain the pace that storage technology changes and the benefits from more frequent updates. These include:

• Greater efficiency in power, space, and cooling with new, higher capacity devices
• Improved performance with system support solid state technology
• New warranty periods for new storage systems rather than relatively expensive maintenance contracts for storage systems past their warranty period
• Improved reliability for new systems.

The discussion then shifts to how difficult it is to move to a new storage system, mainly because of data migration. Some storage systems automatically migrate data from an older storage system, especially if the migration is between different generations of the same system. If the migration is not transparent and automatic, it costs more to move to another generation of disk storage.

It gets more complicated when switching to another vendor or a different architecture from the same vendor. The new system may require administrators to provision and manage the storage differently than the old system. Administrators must understand the differences, learn new tools or administrative interfaces, and set up new procedures to monitor and respond to issues. These add to the acquisition cost when calculating TCO (Total Cost of Ownership) and pose a potential risk before being effectively implemented.

IT teams would obviously like a longer lifespan for storage systems, but changes in technology make tradeoffs skewed towards replacements at regular intervals. And as technology progresses, there may be a point that longer lifespan systems have greater economic advantages than what we have now.

Which storage cloud is fastest?



Posted by: Dave Raffo
Cloud storage, data migration

Do you ever wonder how long it would take to move a dozen terabytes from one cloud provider to another, or even between two accounts in the same cloud?

Probably not, if you’re sane. But maybe you do if you have data in the cloud and think you might want to switch one day for performance or pricing reasons. And you definitely do if you’re a cloud storage vendor that promises service levels that might require non-disruptive cloud-to-cloud migration.

Nasuni fits in that last category, so the vendor conducted extensive testing of what it considers the top three cloud providers based on the stress testing it conducted last year. The latest results are entered in its Bulk Data Migration in the Cloud report issued today.

In case you were wondering, here’s how long Nasuni estimates it would take to migrate a 12 TB volume:

• Amazon S3 to another Amazon S3 bucket: Four hours
• Amazon S3 to Microsoft Windows Azure: 40 hours
• Amazon S3 to Rackspace: Just under one week
• Microsoft Windows Azure to Amazon S3: Four hours
• Rackspace to Amazon S3: Five hours

Nasuni CEO Andres Rodriguez said transmission speeds vary depending on time of day, but the biggest difference is the cloud providers’ write capabilities because S3 had by far the best transfer times.

Nasuni determines the best back-end cloud for its customers, and usually selects S3 with Azure as the second choice. Nasuni’s competitors sell storage appliances and let customers pick their cloud provider, but Rodriguez said Nasuni picks the cloud provider to meet its SLAs.

“Our enterprise customers using storage in their data centers let Nasuni be the one to move data,” he said. “All customers want from Nasuni is storage service. They don’t care about which cloud it’s unless they want data in a specific geographic location. But that’s a location issue, not a provider issue.”

That means Nasuni customers can’t decide to switch providers based on pricing changes, but Rodriguez said he doesn’t recommend that practice.

“This is not an operation you want to be doing dynamically daily so you can save a few cents here and there,” he said. “You do it to take advantage of better features and performance.”

TCO vs. ROI: Remember transition costs



Posted by: Randy Kerns
non-disruptive data migration, return on investment, total cost of ownership

While talking to value added resellers (VARs) recently about selling storage systems, I noticed their presentations about vendor products featured return on investment (ROI) calculations.

These ROI calculations focused on cost of the solution, savings in maintenance, floor space, power, and cooling, performance gains that enabled business expansion or consolidation, and savings in day-to-day administration.

But limiting the economic view of buying new storage technology to ROI does not represent the true financial impact of the transition. Investment in technology also requires a time element to be considered. A specific technology has a lifespan that is dictated by other factors such as warranty periods (and associated service costs), technology replacement and the subsequent unavailability of the earlier technology.

For these reasons, information technology professionals generally focus on total cost of ownership (TCO) when evaluating storage. TCO includes the time element and the transition costs. Notable factors included in TCO calculations include product costs divided by the number of years the product will be in service, data migration costs and operational and administrative costs over the lifespan of the product.

TCO gives a more accurate look in the evaluation of a technology deployment. For example, the cost of one technology product may be less expensive than another but the transition costs may actually make it more expensive. The lifespan is a big factor. If the lifespan is relatively short, that could make it hard to base a decision on product cost.

Vendors recently began trying to address transition cost in storage systems by adding a built-in capability to non-disruptively migrate data to the new technology system. This has become a differentiating characteristic of primary disk storage systems but its impact is limited in archiving and non-existent in tape systems.

Evaluating storage technology solutions must go beyond the simplistic cost of the solution and use of a purely economic measure such as ROI. More detailed evaluation must be done with different factors. Looking at the past technology change rate can be a good predictor for assigning the longevity expectation. TCO, with the correct elements included, can reflect the real costs between different storage technologies and assist in making a more informed decision.

Dell offers deals for EMC, NetApp customers



Posted by: Dave Raffo
compellent, dell storage, emc, equallogic, netapp

Dell is trying to bolster flagging storage sales with a trade-in program that offers cash credits and improved lease terms to EMC and NetApp customers.

The Dell Storage Swap program launched today promises price breaks for organizations willing to retire EMC VNX, Clariion and Celerra and NetApp FAS arrays to move to Dell Compellent and EqualLogic storage before July 31. Dell pledges “specialized migration services,” support and “other financial incentives” for customers who switch.

When a vendor offers such a swap program, you can bet sales are not strong. That is the case with Dell, which has lost market share since ending its OEM relationship with EMC after acquiring Compellent last year. The Compellent deal followed Dell’s 2008 purchase of EqualLogic. Now Dell is banking on customers switching for the incentives and becoming happy enough with the results to stay with Dell long-term.

Even if Dell’s formal swap program is new, the strategy isn’t.

Christopher Patti, director of technology for AccuWeather, said Dell gave him a good enough price to switch from EMC Clariion and Hewlett-Packard EVA storage to EqualLogic in 2008. That was merely months after Dell bought EqualLogic and while it was still an EMC OEM partner. Patti said upgrading his older Fibre Channel arrays from EMC and HP would have cost in the high-six figures. He bought two EqualLogic iSCSI SANs and has since added four more EqualLogic arrays.

“The Clariions and EVAs were ridiculously expensive, especially with day-to-day maintenance, upgrades and extra costs for replication, snapshotting and other things here and there,” Patti said. “Dell gave us a good price point.”

He said he also likes that EqualLogic data protection and management features are part of the base price and not add-on licenses. “Dell’s software makes it easy to manage the array, see where bottlenecks are and know when you have to purchase additional capacity,” he said.

Server vendors Dell, HP and IBM are losing share in the storage market to pure-play storage vendors EMC, NetApp and Hitachi Data Systems (HDS). According to Gartner’s worldwide external disk storage revenue report released this week, Dell’s storage revenue dipped 0.2% from 2010 to 2011 while the market grew 9.8%. Dell’s market share slipped from 8.2% to 7.4% during the year and it stands sixth behind EMC, IBM, NetApp, HP and HDS.

The targets of Dell’s trade-in program, EMC and NetApp, ranked first and second in revenue growth for last year.

cloud storage gateways, cloud storage pricing, cloud storage providers

When Microsoft Windows Azure dropped pricing for its cloud service last Friday, it marked the third cloud price cut of the week. Google and Amazon also dropped prices for storing data on their clouds earlier in the week.

All of this price slashing shows these companies are serious about getting enterprise data into their clouds. But SearchCloudStorage.com assistant site editor Rachel Kossman reports that customers need to do more than just look at a provider’s published list when cloud-shopping. They need to match their use cases to the way the providers price specific transactions or they could be in for a surprise when the bill comes.

Check out her story for details on all the news prices and more tips on getting the best price from cloud storage providers.

Western Digital, Hitachi GST make it official



Posted by: Dave Raffo
enterprise hard drives, solid state drives

Western Digital’s $4 billion-plus acquisition of Hitachi Global Storage Technologies (HGST) officially closed today – a year and two days after the hard drive vendors first declared their intention to merge.

Western Digital is paying $3.9 billion in cash and 25 million shares of its common stock currently valued at $900 million for HGST, the world’s second largest enterprise drive vendor.

The deal had to clear regulation hoops from regulatory groups around the world because the deal makes the combined companies the largest hard drive vendor with 47% of the market, surpassing Seagate’s 32% market share.

HGST owns 9% of the enterprise market compared to Seagate’s 56%. Western Digital has only 1% of the enterprise market and 30% of the overall hard drive market without HGST.

Western Digital said it will operate HGST as a subsidiary, and it will maintain the HGST brand and separate product lines.

HGST’s enterprise products include solid-state drives (SSDs), and it scored a big win this week when it revealed that EMC is shipping Hitachi Ultrastar SSD400S single-level cell (SLC) 2.5-inch SAS SSDs in its VNX unified storage arrays.

Mitch Abbey, HGST’s senior enterprise product line manager, said he expects more SSD qualifications with EMC and other storage vendors. He also said HGST has cheaper multi-level cell (MLC) drives in the works and is reviewing the PCIe market for server-based flash to determine if it’s worth putting out that type of product.
