TMS Ramsan-720 Price - 2D Flash RAID Technology
The TMS Ramsan-720 Dominates Storage Speed With 2d Flash Raid Technology At A Reasonable Price
Enterprise Flash San Data Storage
UPDATE: The TMS Ramsan-820 has been released now following on the heels of the Ramsan-720. This one has a capacity of 24TB in a dense enclosure. Will the TMS Ramsan-920 be next?
"The World's Fastest Storage" is the trademark of Texas Memory Systems and they continue to push the data storage barrier with the release of the new TMS Ramsan-720 flash san storage blade unit. The thin 1U device is looking to blaze entry into datacenters while providing 12TB or 6TB data storage capacity at unmatched speeds and with built-in high-availability features. I was quoted a price of $320,000 for the D-RamSan-720-12TB and a quoted price of $170,000 for the D-RamSan-720-6TB although the price may vary depending on the specific market area and in particular in regards to international markets and regions. These prices are a fraction of what similar performing hard disk solutions would cost. But if data storage speed is crucial to your application performance and you see value in dropping 1/3 of a million dollars to get the bleeding edge flash san storage then you should contact a Texas Memory Systems sales representative to arrange a customer quote to fit your budget accordingly.
The Ramsan-720 2d raid-infused storage unit is a subsequent iteration to the Ramsan-710 introduced earlier in 2011. 2D flash raid 5 technology means that proprietary techniques are used to store data in a RAID 5 configuration both within flash modules and across flash modules in a highly redundant and failover resistant manner. No SPOF is the aim with this enterprise device with a duality in everything including power, management, and data paths. Earlier Ramsan SSDs provided data protection in 3 manners: error-correcting code (ECC), patented Variable Stripe RAID, and 1D module RAID 5. The addition of 2D flash raid 5 adds a fourth layer as an innovation unique to the Ramsan-720 line of product hoping to lessen some of the burden of data protection from the application-level and have hardware do the work.
The system rates at a typical power consumption of 300W-400W from dual power supplies. Texas Memory Systems says that competitors may use "repurposed server parts" while the integrate custom hardware built for the purpose of data storage leading to power consumptions savings of as much as 75% over competing products. Other components such as batteries, data buses, ports, and controllers are also redundant. Batteries are used to in order to synchronize RAM buffers in the even of power failure to insure that all data is written properly to the essentially non-volatile memory. A hotspare fault tolerant flash (FTF) module can be designated so as the array can immediately repair itself from module degradation. Scaling options include up to four 8GBit Fibre Channel or 40GBs QDR Infiniband ports.
The Ramsan-720 2D Flash RAID array stores data on enterprise grade single level cell (SLC) NAND Flash. Some competitors have turned to muli-level cell flash technology and criticize TMS in regards to this. SLC can be more costly to produce since it provides less possible states in individual memory cells as opposed to MLC flash which stores more levels of information within the floating-gate transistors. The Ramsan-720 is going for high-end high-availability and so the SLC as it can provide faster write speeds while consuming less watts of power. Also, cell longevity is a benefit of SLC which the Ramsan-720 unit looks to extend even further through the use of a wear leveling algorithm to give each cell its fair share of write operations.
This 7th generation TS Ramsan is rated at 400,000 IOPS and 5 GB/s bandwidth. Compare that with other solutions and it might just be time to remove spindles for good from your server room.
