Martin wanted to build on a fast data array that could manage both block-data access as a storage area network (SAN) does, and file access as network-attached storage (NAS) devices do.

He picked a $30,000 array from Nimbus Data Systems because it included a 10 gigabit Ethernet connection and actually cost less than similar units from EMC, Network Appliance and other storage companies, most of which didn't offer 10Gbit/Sec Ethernet even for more money.

He uses the array as a central data store for the whole company, though there's a lower-end Nimbus in the New York office as well. The main array talks to two AMD-based servers that support 30 to 40 VMware ESX virtual machines that run all the company's applications, except one retail specialty application that remains on an AS/400.

Martin bought servers with two dual-core processors, but with the ability to upgrade to four quad-core chips, to support a plan to eventually host as many as 75 virtual desktops as well as the existing VMs.

The desktop virtualization project, which will use Citrix software and Xen hypervisors, will tax the servers more, and may require upgrades in processors or memory, but won't come anywhere near the capacity of the Nimbus array or 10Gbit/sec Ethernet connection through which it talks to the world.

Overbuying storage bandwidth and server capacity will actually save money in the long run, not only by extending the useful life of the hardware, but also by making room for virtual desktops and other applications that will themselves save money, Martin believes.

The company's desktop virtualization project is, in part, a way to avoid a coming round of hardware refreshes as laptops and desktops age, as well as consolidating data and IT costs. Being able to launch a virtual desktop from a "golden" image that doesn't change and can't be infected by an end-user's Web browsing habits saves an awful lot of IT trouble-shooting time, plus gives the company better control of its data and risks, Martin says.

Analysts also estimate that 10Gbit/sec Ethernet is more than twice as fast, and cheaper by as much as a third than 4Gbit/sec Fibre Channel, which requires special interface cards and fiber cabling. Combining block and file storage on one unit cuts costs even further, and consolidates administration onto one piece of hardware.

"Down the road I knew 10GigE was going to be the hottest-selling ticket and I didn't want to have to forklift anything out to migrate to it later on," Martin says. "With pictures and files and all the other corporate data on one Nimbus array and right in the middle of a [virtual desktop infrastructure] project, the last thing I needed was to have everyone['s traffic] coming down to one-gig connections . Throughput is becoming the lifeblood of all my information, so it's a really big deal."

Throughput is a big deal, and buying 10Gbit/sec Ethernet to plan for the future shows solid thinking on planning architecture and capacity, Burton Group's Wolf says. Prices for 10Gbit/sec Ethernet should drop substantially in the next six to 12 months, however, so organizations that have to buy more than two or three of the cards for high-capacity servers might do better to wait a while, Wolf says.

Neterion 10Gbit/sec Ethernet cards range between $1,000 and $2,000 for the most part, depending on features, which is substantially more expensive than 1 Gbit/sec Ethernet cards, though far cheaper than Fiber Channel.

Martin plans to increase data throughput even more by upgrading the 12,500-Gbyte disks in the array from 7,200 RPM to versions that run at 15,000 RPM and, eventually, to solid-state drives that store data in RAM chips rather than spinning disks.

"Pairing solid-state drives with 10GigE, the sky's going to be the limit," Martin says. "The limit is only the network speed again. The bigger story has been my finding this storage array that could handle all I needed in one box and VMware being able to support it. When I was able to plug those Neterion cards directly into the ESX boxes, I was like 'oh my god, this is fantastic.' The end users saw an immediate effect."
