Scalable and Versatile SSD Platform
TMS has responded to the need for a fast, scalable platform for data storage with the Tera-RamSan solid state disk (SSD) system. The Tera-RamSan holds between 384 and 1024 GB of fast, non-volatile DDRRAM storage in three to 8 independent SSD modules, each containing its own wide array of redundant high-availability features. If more capacity is required, simply install additional modules without interruption of the system.

The user is given maximum versatility to configure the Tera-RamSan. Since the Tera-RamSan appears as typical storage to the network (up to 512 LUNs), users can arrange some or all of the independent SSD modules in the RAID configuration of their choosing. Other modules may remain independent if desired.

The Tera-RamSan represents our solution to realistic requests from a broad range of entities from the U.S. Military to Fortune 500 companies who have requested Terabyte solid state disks for applications such as:

  • Database acceleration

  • High definition video access/editing

  • OLTP

  • Data retrieval

  • ERP

  • SAN storage

  • And more

Lower DDRRAM prices make the Tera-RamSan a realistic competitor to other Enterprise storage solutions with much smaller RAM caches. The Tera-RamSan offers industry leading price-per-IOPS.

The Tera-RamSan incorporates specially designed 4-Gbit Fibre Channel or 4x InfiniBand interfaces that include performance-enhancing hardware to reduce I/O latency to under 14 microseconds. With I/O requests being served so quickly, an order-of-magnitude more requests per second are executed by a single Tera-RamSan interface as compared to other Fibre Channel interfaces. By scaling SSD modules up to 8 units (8 Fibre Channel links per unit or 4 InfiniBand links per unit), the Tera-RamSan is the ultimate storage solution for high-performance applications in total IOPS and total bandwidth. Also, because the Tera-RamSan is DDRRAM based, there is NO penalty for RANDOM accesses. Data requests need not be tuned for performance. User access time is not compromised, even if tens of thousands of users access the system simultaneously. Extreme performance is the key feature of the Tera-RamSan.

High Availability and Reliability
Each Tera-RamSan module contains its own internal backup and battery systems, ensuring the persistence of data even in the case of total power loss. Should one or all of the modules lose power, internal batteries keep the unit active for one hour. After a user-specified period of time, the unit backups all of its data to internal redundant, hot swappable hard disks if power has not yet been restored. In addition, each SSD module includes redundant, hot swappable cooling fans and redundant, hot swappable power supplies -- each with an independent power input.

Manageability
The Tera-RamSan solution is conceived as both a single system and the combination of independent storage subsystems. The manageability features of the Tera-RamSan reflect this fact. At the independent module level, each SSD has the same manageability features as the RamSan-400 SSD, including Telnet configuration functionality, an on-site front panel display, SNMP compatibility, and a browser-based Java monitoring applet.

Administrators may view all modules at once through the TeraWatch monitoring software. This presents a summary view of all installed SSD modules, providing a single point to monitor the performance and any potential problems with the SSD modules. Since the SSD modules are SNMP compatible, this can also be achieved through whatever standard SNMP listening application is commonly used.
