SSD now available for Oracle PC laptops.

* Understand how SSD causes huge performance improvements for I/O intensive Oracle databases.

* Use proven techniques for the selective application of RAM disk.

* Learn who to tune an entire database by speeding-up the I/O sub-system.

Samsung says the SSD's outperforms a comparably sized HDD by more than 150 per cent. The company quotes the storage disk as reading data at 57 Mbytes per second (MBps) and writes at 32MBps.

Samsung will be marketing a range of NAND based SDDs. These include a 2.5-inch drives fitted with 16 NAND Flash devices of 4Gbit or 8Gbit density for 8Gb and 16Gb of storage respectively. At the lower end there will also be 1.8-inch drives will offer 4Gb or 8Gb capacities.

The 1.8-inch sized drive will be available in August, 2005 for sub-notebook and tablet PCs

2008 Market Survey of SSD vendors for Oracle: There are many vendors who offer rack-mount solid-state disk that work with Oracle databases, and the competitive market ensures that product offerings will continuously improve while prices fall.  SearchStorage notes that SSD is will soon replace platter disks and that hundreds of SSD vendors may enter the market: "The number of vendors in this category could rise to several hundred in the next 3 years as enterprise users become more familiar with the benefits of this type of storage." As of June 2008, many of the major hardware vendors (including Sun and EMC) are replacing slow disks with RAM-based disks, and Sun announced that all of their large servers will offer SSD. As of June 2008, here are the major SSD vendors for Oracle databases (vendors are listed alphabetically): Advanced Media Inc. EMC software MTron Pliant Technology SeaChange Solid Access Technologies Sun Microsystems Texas Memory Systems 2008 rack mount SSD Performance Statistics SearchStorage has done a comprehensive survey of rack mount SSD vendors, and lists these SSD rack mount vendors, with this showing the fastest rack-mount SSD devices (as of May 15, 2008): manufacturer model technology interface performance metrics and notes Texas Memory Systems RamSan-400 RAM SSD Fibre Channel InfiniBand 3,000MB/s random sustained external throughput, 400,000 random IOPS Violin Memory Violin 1010 RAM SSD PCIe 1,400MB/s read, 1,00MB/s write with ×4 PCIe, 3 microseconds latency Solid Access Technologies USSD 200FC RAM SSD Fibre Channel SAS SCSI 391MB/s random sustained read or write per port (full duplex is 719MB/s), with 8 x 4Gbps FC ports aggregated throughput is approx 2,000MB/s, 320,000 IOPS Curtis HyperXCLR R1000 RAM SSD Fibre Channel 197MB/s sustained R/W transfer rate, 35,000 IOPS   Choosing the right SSD for Oracle When evaluating SSD for Oracle databases you need to consider performance (throughput and response time), reliability (Mean Time Between failures) and TCO (total cost of ownership).  Most SSD vendors will provide a test RAM disk array for benchmark testing so that you can choose the vendor who offers the best price/performance ratio. Burleson Consulting does not partner with any SSD vendors and we provide independent advice in this constantly-changing market.  BC was one of the earliest adopters of SSD for Oracle and we have been deploying SSD on Oracle database since 2005 and we have experienced SSD experts to help any Oracle shop evaluate whether SSD is right for your application.  BC experts can also help you choose the SSD that is best for your database.  Just  call 800-766-1884 or e-mail.:  for SSD support details.
