The RamSan-220 has been replaced by the cheaper and faster RamSan-320.
All current RamSan-210/220 customers will continue to be supported. For
further details, contact TMS.
Accelerate OLTP, batch processing and other intense applications with the RamSan-220 solid state disk (SSD) from Texas Memory Systems. Placing hot data on a RamSan allows maximum return on existing critical applications and hardware.

Performance is key to a quality solid state disk. Outside of the RamSan-320, the RamSan-220 is the World's Fastest Storage®. The system delivers 450 MB/second of bandwidth and 200,000 random I/Os per second.
Competing solid state disks that have less internal bandwidth than the RamSan-220 cannot support all of the applications that we support and cannot be shared with as many hosts without compromising performance. Our nearest competitor claims half of our available bandwidth.
An important note as you compare solid state disk to RAID: our solid
state disk bandwidth numbers can be sustained with random data streams.
RAID systems can only sustain high bandwidth numbers with sequential
I/Os Per Second (IOPS)
The RamSan-220 can deliver 200,000 random IOPS to your applications. A single port on the RamSan-220 can provide 100,000 random IOPS. The reason that we stress "random IOPS" is that RAID manufacturers occasionally cite their IOPS performance. Discerning buyers should be aware that these numbers are almost always sequential IOPS performance. The problem with sequential IOPS is that there are almost no applications in the real world that result in sequential small block disk access.
So why do you need IOPS? IOPS are needed to process database transactions. Database transactions have two main characteristics: they are small (averaging around 8K) and they are random. Small random file accesses thrash hard disk drives. In fact, a really good disk drive can provide around 300 random IOPS. A fast RAID can handle 5,000 random IOPS. Which brings us back to original question, it is important to support a high number of IOPS because your servers can support a high number of IOPS. The latest processors are operating at over 3 Gigahertz per second. However, since the early 1980s processors have been faster than storage. Over the last twenty years, the gap between processor performance and storage performance has widened.
When your processor is faster than your storage, then your processor literally waits on storage for data needed to perform calculations, this is called I/O wait time. If your processor is waiting, then your users are waiting. On top of that, you are wasting a significant investment in the latest processors.
By supplying incredibly high random IOPS, the RamSan-220 eliminates I/O wait time for all files that it stores. Because its random IOPS capabilities are so amazing, it is possible for a single RamSan-220 to provide I/O acceleration for multiple host servers.
When you consider our combined bandwidth and random IOPS performance
it is clear why we call RamSan "The World's Fastest Storage®".
Peace of Mind
The RamSan-220 is a non-volatile solid state disk. Redundant lithium
Ion batteries will power the system for up to one hour in the event of
external power failure. Mirrored and hot-swap SCSI hard disk drives
provide persistence in the event of an extended power failure. The
RamSan-220 is the only solid state disk in its class to offer mirrored
and hot swappable SCSI disk drives. This approach provides a system
administrator additional Peace of Mind when using a RamSan-220, when
power is restored to the RamSan it will automatically copy data from
the mirrored disk drives to the memory. The RamSan can restore 32
GB of data from disk to memory in approximately 15 minutes.
No Excuses Operation
Texas Memory Systems has also implemented hardware fail over between controllers on the RamSan-220 in a switched environment. The controllers can be configured as Active:Passive or Active:Active. If they are implemented in Active:Passive mode, and a link/controller fails, the other controller automatically takes over.
Together the redundancy and hot swappable features of the RamSan-220
put it in the same league with the finest of enterprise computing hardware.
Room to Grow
Our newest Fibre Channel interface is the FC-34. Each FC-34 includes two 2Gbit Optical (SC) Fibre Channel interface ports. The FC-34 supports both 2Gbit and 1Gbit devices, and auto-negotiates to operate in the proper mode. If both ports are connected to the same host, they can be used in an active-active configuration or in a fail-over mode in a switched environment. The FC-34 supports all three of the topologies available under the Fibre Channel protocol:
If you have followed Texas Memory Systems over the last year, you
know that we have invested a lot of effort in ensuring that our Fibre
Channel interfaces are interoperable with other storage network components.
In fact, our RamSan-520 was the first solid state disk to pass Brocade's
Fabric Aware interoperability certification. In this test, the RamSan-520
was put into a network of heterogeneous storage network components.
The RamSan-220's predecessor, the RamSan-210, was the first solid state
disk to be both certified Solaris Ready and Designed For Windows 2000.
For on-site management, the RamSan-220 display gives users vital information about the operation of the unit. The display, pictured below, provides the ability to:
The RamSan-220 includes the Management Control Port (MCP) which is accessed through Ethernet. Administrators can telnet into the RamSan-220 in order to perform the following management tasks:
For remote management, the RamSan-220 is shipped with a Java-enabled remote monitoring software. The software allows users to:
The remote monitoring software supports SNMP.
