The RamSan-325c, TMS' eighth 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-325c is The World's Fastest Storage®.
No RAID, no cache, no other solid state disk is capable of the raw
performance offered by the RamSan-325c.
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 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-325c 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-325c includes hot swappable redundancies wherever physical wear is
a factor, such as power supplies and backup hard disks. It also includes
three 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-325c is designed to look like a simple Fibre Channel 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 vendors including Cisco, Emulex, Brocade,
McData, QLogic, LSI Logic, and Vixel easily interoperates with the
RamSan.
Active Backup and Chipkill Technology: The Newest Innovations in
SSD
Exclusive to the RamSan is Active BackupTM 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-325c 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-325c 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.
