five nines of availability,
uptime
Google’s Gmail service was down for “about 100 minutes” yesterday, according to Ben Treynor, its VP of engineering and site reliability czar. The outage caused a flurry of conversation online, particularly from Gmail users on Twitter, who flooded the site with messages using the “#googlefail” hashtag.
According to Treynor, the problem came about due to not enough capacity and insufficient routing of network traffic during routine maintenance.
“(W)e took a small fraction of Gmail’s servers offline to perform routine upgrades,” Treynor wrote. “However, as we now know, we had slightly underestimated the load which some recent changes (ironically, some designed to improve service availability) placed on the request routers — servers which direct web queries to the appropriate Gmail server for response.”
Some request routers became overloaded and transferred the load to other request routers, which in turn became overloaded themselves, and the situation snowballed.
Treynor concluded that the Gmail team will make improvements over the next few weeks, but tempered that by writing that “Gmail remains more than 99.9% available to all users…”
Wow, that sounds like a lot, doesn’t it? 99.9% available? When you break it down, 99.9% availability is equal to almost nine hours of downtime over the course of a year. That might be OK for a normal person using Gmail for personal use, but businesses that rely on it might not be happy. For comparison’s sake, if Gmail had four nines of availability, it would have 53 minutes of downtime every year; the holy five nines of availability (99.999%) would equal five minutes of downtime.

DataCenter,
it jobs,
data center jobs
According to a new report from the IT job research firm Foote Partners LLC, the IT job losses have slowed down in the U.S., and Canada actually posted a net gain in technology jobs.
David Foote, CEO and founder of the firm, said certain non-certified job skills are recession proof — including virtualization, IT architecture, business process, network security management and others. You can find the rest of Foote’s IT skills hot list with the full Foote IT job market report.

System administrators,
sysadmin
I just heard that today is the 10th Annual Sysadmin Day. From the website:
A sysadmin unpacked the server for this website from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong. All to serve this webpage.
A sysadmin installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.
A sysadmin makes sure your network connection is safe, secure, open, and working. A sysadmin makes sure your computer is working in a healthy way on a healthy network. A sysadmin takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.
So if you’re not a sysadmin, honor them today and file a random Helpdesk ticket. And make sure that no matter how menial the problem, mark it “urgent.” If you’re in a real giving mood, order some Domino’s pizza and a case of Mountain Dew for lunch. The sysadmins will be eternally grateful.

IBM Power,
multicore processor
IBM this week revealed details about its upcoming Power7 processor, confirming that it will be a 45-nanometer chip with 4, 6 or 8 cores. Each core will have up to 4 computing threads, meaning there could be up to 32 threads on a single Power7 chip.
The Power7 processor is expected out next year, with Steve Sibley, IBM Power Systems platform manager, saying IBM will try to get it out by mid-year. Other details on the chip: It will use DDR3 memory, have expanded cache and included embedded DRAM. Sibley wouldn’t disclose clock speeds but it is expected to be in the 3-4 GHz range. He said more details will come out at the HotChips conference next month in California.
Assuming the Power 595 server will retain its current architecture of up to 32 sockets, that means with Power7 chips it could have up to 256 processor cores and 1,024 computing threads.
Of course, IBM doesn’t want its Power Systems customers to wait around until the Power7 is released. So it announced a swap program. Users who have or buy a Power 570 or a Power 595 box now will be able to swap the Power7 processor book in for the Power6 or Power6+ processors they have there now. When I asked why lower-end systems weren’t involved in the swap program, Sibley said there is less interest among users in upgrading lower-end systems. When those servers get outdated, he said, end users tend to just move them to test and development environments.
Part of IBM’s goal is obviously to prevent the sales lull that often comes before a new chip release, but it also gives users options for buying now and swapping later without switching up the box’s serial number. In addition, swapping in the Power7 chips will not cost as much as buying a whole new box, though IBM hasn’t released any prices. Finally, the swap program is back-dated, so you don’t need to buy a box right now to get the swap. If you have a Power6 or Power6+ 570 or 595 now, you will be eligible for a serial-number protecting upgrade.

Sun Microsystems and Fujitsu have announced that it will now sell servers with UltraSparc T2 chips that have speeds up to 1.6GHz. The previous top speed was 1.4Ghz.
One of the criticisms of the UltraSparc chip is that it runs at a lower frequency than other RISC/EPIC processors, especially when compared to IBM’s Power chip. That presumably puts it at a disadvantage when it comes to online transaction processing and performing trades, for example.
David Simon, a chairman at software as a service (SaaS) company SearchForce.com, is a Sun server user who said that though the UltraSparc’s frequency might be low compared to Power, its bus architecture allows more transactions to be processed in parallel, thus completing more total transactions in the same amount of time.

Sun Microsystems,
Oracle,
Acquisition,
Java
Though Sun shareholders may give the thumbs-up to a merger with Oracle in a meeting today, users shouldn’t expect it to be complete for months, despite Oracle’s claims and hopes.
Two weeks ago, Oracle announced that the U.S. Justice Department had issued a request for more material in its antitrust review of the merger between the two big technology companies. The request, according to Oracle, was regarding the way in which Java is licensed once Sun becomes a part of Oracle. Richard Jones, vice president of data center services for The Burton Group, said that if Oracle were to start changing the Java license, it would be “shooting itself in the foot.”
Oracle added that despite the request, it still hoped to complete the acquisition this summer. But according to a story in the Wall Street Journal, second requests from the Justice Department do not generally happen that quickly. They are measured in months, not days.
In testimony delivered in late 2007, Thomas Barnett, former head of the Justice Department’s antitrust division, said the average length of a second-request review was 154 days. A similar length of time would have Oracle receiving the Justice Department’s blessing to close the Sun acquisition no sooner than late November.
Some antitrust experts say second-request investigations can take even longer. John Harkrider, an antitrust practice co-chair at the law firm Axinn, Veltrop & Harkrider LLP, who has been retained by the Justice Department to investigate antitrust issues in the past, said he advises clients to allow for six to nine months for such reviews.
“If you move heaven and earth to comply, you should certainly be able to do it within six months,” Harkrider said.

Supercomputing,
Green computing
The 5th annual list of the most energy efficient supercomputers was published recently. IBM took the top four spots and 18 out of the top 20. The Green500 list is dominated by BladeCenter clusters and the Power-based Blue Gene supercomputer.
The list is compiled and sorted by megaflops per watt. The winner was a BladeCenter QS22 Cluster out of the University of Warsaw in Poland running at about 536 megaflops per watt. Incidentally, the same cluster is ranked 422nd in the TOP 500 supercomputer list.
Perhaps most impressive of all the supercomputers is a BladeCenter QS22/LS21 cluster run by the U.S. Department of Energy. It is #1 on the TOP 500 list and #4 on the Green500 list.

INtel Xeon,
Intel Nehalem,
x86 processor
According to a report in Digitimes, which cites anonymous industry sources, Intel will launch four more Xeon server chips early next month.
The quad-core chips include processors in the 5500 (ie. “Nehalem”) and 3000 Xeon chip line. Let’s take a look:
- W5590: You can see here that the quad-core W5580 runs at 3.2GHz with 8MB of cache and consumes 130 watts. Expect the W5590 to have a slightly faster clock speed, as that seems to be the pattern.
- L5530: The L5520 is a lower-power quad-core chip (60W) running at 2.26GHz with 8MB of cache. Again, expect a slightly higher clock speed.
- W3580: From the specification page for the 3000 series, you can see that the W3570 is a quad-core chip running at 3.2GHz with 8MB of cache and consuming 130 watts.
- W3550: The W3540 is a quad-core chip running at 2.93GHz, 8MB cache, 130W.
A couple months ago, Intel showed off the so-called Nehalem-EX chip, an eight-core processor from the Xeon 7400 series that is expected out later this year.
