"eBay Installs 100 TBs of Nimbus Flash Memory Storage for Virtualization"
World-class virtualization deployment sees provisioning times slashed
from 40 minutes to 3 minutes with Nimbus S-Class systems
August 2, 2011
"... today announced that eBay, the world's largest online marketplace,
has deployed more than 100 terabytes of Nimbus S-Class flash memory
to power its VMware virtual server infrastructure. The scale of
the Nimbus deployment at eBay, which started with one system and
expanded to 12 systems in less than one year, makes it among
the world's largest consolidated deployments of network-attached flash
storage for virtualization today."
"... eBay required a storage solution with tight integration with VMware
virtual infrastructure, iSCSI connectivity over 10 Gigabit Ethernet,
ease of administration, and inline deduplication to reduce storage
capacity requirements. In the end, eBay was most attracted to
the performance, efficiency, simplicity, and comprehensive SAN and NAS
software capabilities of the Nimbus Sustainable Storage? platform."
まずは 1台から、じょじょに追加して 12台で 100TB超ですね。
あ、こちらのプレスリリースも重要ですね (実際はこっちのが重要かも)：
"Nimbus Unveils Next Generation S-Class Flash Memory Systems"
Increases Performance by 3x and Broadens Reach with Fibre Channel and
Infiniband Connectivity
August 2, 2011
"... The new line, which retains the S-Class designation, is three times
faster than the original launched in 2010. In addition, the new S-Class
adds support for Fibre Channel and Infiniband networking natively,
in addition to the existing 10 Gigabit Ethernet and Gigabit Ethernet
support, making the new S-Class the most versatile network flash memory
systems on the market today."
*) 3x More Performance
*) Fibre Channel and Infiniband Connectivity
*) The Industry's Most Versatile Flash Memory Systems

"Before Nimbus came onto the scene, eBay had VMware ESXi v4.1 with
thousands of hosts, and NetApp FAS iSCSI and 3PAR SAN storage arrays,
with about 3PB of installed storage capacity in total. It wanted
to roll out standard "Pods" for virtualisation and these had
to serve VMs on demand to thousands of hosts."
"The Pods are are standard combinations of servers, vSphere, storage
and networking: converged IT stacks in effect." ... "It chose Dell
blade servers and Cisco networking." .....

S-class refresh
"The system uses 24 flash modules, not standard off-the-shelf solid
state drives (SSDs), with different flash densities per module
to provide the 2.5, 5 and 10TB capacity points.
Isakovich said: "We have developed new flash modules which deliver
about two and a half times the performance of our first generation
modules."
The S-class also has a new 144Gbit/s mid-plane with a fully
non-blocking architecture so that all 24 flash modules get full
bandwidth and there's no over-subscription. There are also
12 processor cores instead of the previous 8."
Thomas Isakovich, Nimbus CEO
.....
"Up to 25 S-class enclosures can be stacked in a rack to get to 250TB
of capacity, inside a single file system."
