Violin Intelligent Memory Modules (VIMMs)
A VIMM, illustrated in Figure 2.1 :
• Contains memory and interconnect diagnostics and error correction for
data reliability.
• Offers data protection via a flash RAID (4+1Parity) function that provides
fault tolerance and low latency access to flash.
A fully populated system contains up to sixteen Parity VIMMs and four spare
VIMMs for failure protection. All memory modules are hot swappable with
automated rerouting that will not interrupt data service. In the case of a module
failure where the module must be replaced, the Memory Array does not have to
be powered down.

WARNING!
Insert VIMMs or VIMM blanks only, otherwise permanent
system damage will result.
