RamSan-500 highlights:

• The World's Fastest Storage™
• Cached Flash RAID for the Enterprise.
• 1TB to 2TB Flash RAID.
• 16GB to 64GB DDR Cache.
• 100,000 random I/Os per second sustained (reads from flash)
• 2 GB per second sustained bandwidth (to flash)
• Full array of hardware redundancy to ensure availability.

Performance
The RamSan-500 is the perfect combination of performance, price and capacity. With up to two terabytes of capacity, the system provides ample space for storing entire databases or frequently accessed files. Through its 4Gbit Fibre Channel or 4x InfiniBand ports the system is capable of over 100,000 random IOPS or 2 GB/second of sustained bandwidth (even with cache misses).

The RamSan-500 appears simply as a very, very fast disk to the network, able to act as any disk or storage system might. The RamSan-500 can accelerate numerous applications across industries. It is best known for drastic performance gains in read intensive environments such as read-intensive OLTP environments, data warehousing, video on demand and rendering and yet provides strong write performance.

Reliability
There is no tradeoff in reliability for this performance. The RamSan-500 includes hot swappable components or redundancies wherever physical wear is a factor, such as power supplies and flash memory. It also includes two independent internal UPS systems to ensure that no power loss or power supply failure will stop the RamSan from flushing data from the DDR RAM to the Flash RAID. Redundant cooling fans and redundant failover data ports (optional) are also part of the sophisticated design.

In order to conquer enterprise concerns related to the reliability of flash memory, the RamSan-500 is engineered with multiple layers of protection. First, the flash memory in the RamSan-500 is ECC protected. The ECC protection protects data in the event a single bit error occurs. Secondly, the nine flash memory modules in the unit are RAID-5 protected (and hot swappable). If a single module returns a multi-bit error, the data is corrected by built in parity. Third, the RamSan implements bad block retirement. If a bad block is identified, the suspect block is no longer used. Fourth, the system has a large write cache which aggregates small block I/O into larger writes in order to limit the number of writes to the flash memory. Finally, the RamSan-500 also implements wear leveling routines to improve the write endurance of the system. For data with exceptionally high writes, the RamSan-400 is still the preferred solution.

Interoperability
The RamSan-500 is designed to look like a disk to the network or operating system. Therefore, it is highly interoperable and works in virtually any enterprise environment. It can be installed in numerous environments, including Apple OS X, AIX, Solaris, Linux, HP-UX, OpenVMS and Windows. Hardware from Fibre Channel and InfiniBand vendors including Cisco, Emulex, Brocade, McData, Mellanox, QLogic, and LSI Logic easily interoperates with the RamSan.

When contacting Reactive Customer Service please have the Reactive part number, the serial number and a detailed description of the problem. All returned goods must be shipped freight prepaid in the original boxes and packing materials, with the Reactive RMA number prominently displayed on the outside of each shipping container. Once the RMA has been issued, the items must be returned to Reactive within thirty (30) days, or else the RMA will be cancelled.

SILVER WARRANTY - Advanced Parts Replacement
Reactive Data LTD Silver Warranty may be purchased which provides all of the features of the Bronze plan. In addition, for one to three years (customer option), Reactive will ship a new replacement part to the install site for delivery the next business day if, in the judgment of Reactive, an issue as described by the customer is the result of a defective part. Reactive must be notified by 2:00 p.m. GMT in order to guarantee next day shipping. The customer is responsible for shipping the defective part back to the factory no later than ten days after receipt of the replacement hardware. If Reactive has not received the defective hardware after this time, the customer will be charged the full price of the replacement hardware. The customer is responsible for shipping costs. Silver warranty option must be purchased at time of equipment purchase, and does not extend the basic warranty by default.

GOLD WARRANTY - On-site Repair - Business Hours
