"Cache IQ Announces Industry's First Smart NAS Acceleration Solution"
RapidCache dramatically increases application performance and tames
the out of control growth of network attached storage
September 19, 2011
http://www.cacheiq.com/about/company-news/press-releases-2/
"Cache IQ, an enterprise storage solutions company, announced today
the limited release of their RapidCache solution. This intelligent,
high-performance network attached storage (NAS) caching appliance
delivers enhanced performance to I/O intensive applications while
relieving overburdened storage subsystems. RapidCache identifies
applications' active data sets, and then uses a combination of
DRAM and SSDs to dramatically improve performance."

※ここの仕組みも良く解ってません。
とのざっと見た違いは、RapidCacheは "Flow Director" と "Data Server"
の 2機種構成です。Data Serverの搭載メディア (D-RAM/SSD)、接続台数は
自由なようです (実運用中の増設可能かは解りません)。
Data Server (Virtual Tier) の自由度を強調している感じがしますが、
(将来のメディア候補は PCIe Flash, iSCSI, FCoE等)、設置台数を含めて、
設計が重要ですね。当然、キャッシュヒット率等の管理ツールの完成度が
重要なカギとなりそうです。
う～ん、Intelligent High Performance NAS Cache Platform

"Avere menaces NetApp with accelerators"
Promises satisfaction without short-stroking
19th September 2011, The Register
http://www.theregister.co.uk/2011/09/19/avere_threatens_netapp/
"Avere says it is capturing business that would have gone to NetApp
because its clustered accelerators cost less than NetApp storage
upgrades, and run faster."
.....
"Up to six FXT nodes can be clustered together and any NFS-using
filers can be accelerated by Avere. It is focusing on NetApp
and EMC because they are the big fish in its sea. El Reg
was briefed by Avere CEO Ron Bianchini on a couple of recent wins
against NetApp."
以下導入例の紹介で、最後に
"Bianchini says Avere FXTs have been used in front of BlueArc
filers too. But, we said, these are hardware-accelerated and
go fast. "No it doesn't," Bianchini replied: "It's one box and
eventually the box runs out of gas... We sit in front of BlueArc,
Isilon, whatever.""
