LSI SAS MegaRAID products power IBM System x servers

ServeRAID controllers support both SAS and SATA hard disk drives

By CBR Staff Writer

LSI has announced its 6Gb/s SAS MegaRAID products are shipping on two new IBM System x servers, enabling new levels of server storage performance.

The IBM rack-mount servers, with integrated LSI 6Gb/s SAS technology, provide end customers with cost-effective offerings for web serving, e-business, collaboration, distributed database, SAP deployments and virtualisation, the company said.

LSI claims that the 6Gb/s SAS MegaRAID products demonstrated a 190% throughput improvement for RAID 5 writes and a 240% throughput improvement for RAID 6 writes compared to products based on 3Gb/s SAS technology, translating to significant system performance gains.

According to LSI, the LSISAS2108 6Gb/s SAS RAID-on-Chip (ROC) and MegaRAID software are integrated into IBM ServeRAID controllers found in IBM Systems x3650 M2 and x3550 model servers. The ServeRAID controllers, which are designed for inside-the-box connectivity, feature eight internal 6Gb/s SAS ports and support both SAS and SATA hard disk drives. An additional level of data security is available by using LSI SafeStore encryption services with self-encrypting drives (SED).

The company said that the ServeRAID controllers provide RAID 6 support to protect against data loss in the event of dual-drive failures. The controllers also feature LSI MegaRAID Storage Manager software, for access to disk encryption and RAID setup and management and an intelligent battery backup unit that provides battery capacity monitoring.

Kelly Bryant, business line director of DAS RAID for engenio storage group at LSI, said: LSI has collaborated with IBM to provide market-leading storage technologies and software management solutions. LSI SAS and MegaRAID technology provide the performance, scalability and data protection that IBM System x Server customers require to achieve the best return on their IT investments.
