The RamSan-300, TMS' eleventh generation solid state disk, is simply the
most advanced SSD on the market today. Its fast DDRRAM storage is ideal
for storing performance-demanding data and accelerating application
performance. In fact, the RamSan-300 is The World's Fastest Storage®.
Performance
|
TMS' numerous customers have seen real-world performance increases
from 2x to 25x simply by installing a single RamSan. It plugs into
servers or fabrics through basic Fibre Channel or InfiniBand connections and appears
simply as a very, very fast disk to the network, able to act as any disk
or storage system might. The RamSan-300 can accelerate numerous
applications across industries. It is best known for drastic performance
gains in OLTP, batch processing, and other intensive
operations. |

Reliability
There is no tradeoff in reliability for all this performance. The
RamSan-300 includes hot swappable redundancies wherever physical wear is
a factor, such as power supplies and backup hard disks. It also includes
two independent internal UPS systems to ensure that no power
loss or power supply failure will stop the RamSan from performing its
internal backup procedures. Redundant cooling fans and redundant
failover data ports (optional) are also part of the sophisticated
design.
Interoperability
The RamSan-300 is designed to look like a disk to
the network. Therefore, it is highly interoperable and works in
virtually any enterprise environment. It is installed in numerous
environments, including Apple OS X, AIX, Solaris, Linux, and Windows.
Hardware from Fibre Channel and InfiniBand vendors including Cisco, Emulex, Brocade,
McData, Mellanox, QLogic, LSI Logic, and ATTO easily interoperates with the
RamSan.
Active Backup and Chipkill Technology: The Newest Innovations in
SSD
Exclusive to the RamSan is Active Backup® software. Other
SSDs and cache system can only "destage" data from RAM to
backup disks once power is already lost. This means that data is never
backed up during normal operation and the time-to-complete-backup after
power loss is unacceptably long. A RamSan-300 with Active Backup can
continuously backup data on RAM to the internal backup hard disks
without impacting performance. This means in an emergency situation,
data is anywhere from 60-100% on the backup hard drives already. RamSan-300 systems take reliability even farther by implementing IBM
Chipkill technology. Standard error correcting code (ECC)
implementations correct single-bit data errors in memory chips but
cannot correct the multi-bit errors that can result in data integrity
issues. Chipkill technology allows a memory system to correct a
multi-bit failure up to and including a total chip failure.
Soft Error Scrubbing
The RamSan-300 is the first solid state disk to include soft error scrubbing.
All solid state disks can correct a single bit error before sending data to
the server as a part of their ECC protection. The RamSan-300, however, goes
a step further by scrubbing; re-writing the corrected data to memory and then
verifying the re-write to determine if a memory chip has a failure (a hard
error) or if radiation transients caused the single bit error (a soft error).
Systems that do not scrub single bit memory errors will either a) report
errors to a system log that will eventually encourage replacement of a memory
board or b) hide these errors thus leaving a potentially unsafe memory board
in the system. Research on this topic suggests that 90% of single bit errors
are soft errors. In these cases, the RamSan-300 will correct the error
through the scrubbing process and prevent unnecessary downtime to replace
the memory board.
