Ram-San 400 Product
Highlights
• The World's Fastest Storage®
• First solid state disk with 4Gb Fibre Channel interfaces.
• First solid state disk with 4x InfiniBand interfaces.
• Over 400,000 random I/Os per second.
• 3000 MB/s random sustained external throughput.
• Full array of hardware redundancy to ensure availability.
• IBM Chipkill technology protects against memory errors up
to
and including loss of an entire memory chip.
• Exclusive Active Backup® software constantly backs up
data
without any performance degradation. Other SSDs only begin
to
backup data once power is already lost.
The RamSan-400, TMS' tenth 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-400 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-400.
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-400 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-400 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-400 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 Vixel 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-400 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-400 takes 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
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-400,
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-400
will correct the error through the scrubbing process and prevent
unnecessary downtime to replace the memory board.

Reliability and Availability
• Chipkill technology protects data against memory errors
up to
and including loss of an entire memory chip
• Internal redundancies
- Power supplies and fans
- Backup battery power (n+1)
- Backup hard disk drives (RAID3)
• Hot-swappable components
- Four backup hard drives (front access)
- Power supplies
• Soft Error Scrubbing
- When a single bit error occurs on a read, the RamSan
will automatically
re-write the data to memory
thus scrubbing soft errors. Following
the re-write the system re-reads
to verify the data is corrected.
Backup Procedures
Supports two backup modes that are configurable per system or per
LUN:
• Data Sync mode - synchronizes data to redundant internal
disk drives
before shutdown or with power loss
• Active BackupTM mode (optional) - backs up data constantly
to internal
redundant disks without impacting system performance.
