The RamSan-330 turbocharges storage by caching the
most popular data and distributing it at maximum rates of 3 GB/s
bandwidth and 250,000 I/Os a second. End users can use the RamSan-330 to
overcome the costly bottlenecks associated with slow read/write
performance across a large segment of data. While some intensive
applications need a terabyte of solid state disk to fully perform, many
others could simply benefit from a large cache such as the RamSan-330 to
make terabytes of RAIDs behave like solid state disk.
The state-of-the-art caching algorithms and
firmware built in to the RamSan-330 support three widely used caching
through caching: the server is not notified that a write is
committed until it is written to disk.
caching: all writes are to the RamSan-330. In the background, the
system uses available bandwidth to flush writes to the external
caching: Optimizes reads by prefetching blocks from disk in
anticipation of system storage requests.
methods are configurable per system or per segment.
