  "Violin Memory's V6000 flash storage array has exceptionally low
   and consistent latency as proven on audited TPC-C benchmarks.
   One reason: they don't use standard SSDs. Instead they use
   Violin Intelligent Memory Modules - VIMMs - that, unlike DIMMs,
   are hot swappable."

Storage Gagaによる、vRAIDに関してもう少し踏み込んだ解説：
"We raid vRAID"
 March 8, 2012, Storage Gaga
  http://storagegaga.com/we-raid-vraid/

  "I took a bit of time off to read through Violin's vRAID technology
   because I realized that vRAID (other than Violin's vXM architecture)
   is the other most important technology that differentiates
   Violin Memory from the other upstarts. ..."

以前紹介した Berkeley RAID (つまり RAIDの起源) から、現状の新規 RAIDに
触れ (ただし Panasasは declustered RAIDより Object-based RAIDのが正しい
表現ですが)、NAND Flashの特徴を解説し、flash-optimized vRAID technology
の詳細に進んでいきます (内容は省略)。
