ServeRAID technology also allows data to be stored redundantly, across multiple hard disk
drives— enhancing both the integrity and the availability of the data. SAS and SATA ServeRAID
controllers offer enhanced performance due to onboard processors and cache. Because IBM
ServeRAID controllers can help significantly improve data transfer rates, this technology is
extremely effective when implementing demanding, transaction-oriented applications. By
employing the advanced fault tolerance of IBM ServeRAID technology, companies can
effectively implement networked business systems that require large amounts of storage space
for data and applications that must be available for their businesses to continue operating.
The optional integrated ServeRAID-MR10k SAS/SATA controller offers enhanced performance
over the integrated LSI 1078 SAS controller, 256MB of battery-backed cache memory, and
supports seven RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 5 (striping
with parity), and 6 (striping with double parity), 50 (striping with parity across multiple arrays)
and 60 (striping with double parity across multiple arrays). Note: RAID-50 and -60 require
external storage, due to the minimum requirement of six or eight drives, respectively.
External SAN, NAS and direct-attach storage is available using one of several IBM System
Storage
™
and TotalStorage
™
host bus adapters.
The IBM TotalStorage DS4000, DS6000, and DS8000 series, as well as the System Storage
DS4000, N3000, N5000, and N7000 series, comprise a powerful and broad shared storage
family with integrated management software designed to meet midrange and enterprise needs.
