Originally published at Internet.comLSI's MegaRAID product line consists of multiple flavors of PCI format controller cards that provide RAID data protection to host system drives. The cards are available with support for many types and numbers of drives (varying in the number of physical and logical drives, channels, and RAID levels supported) including cards for SATA, SCSI, and SAS drive interfaces.
Among the currently available card configurations are the following:
- SATA 150-4: Four-port serial ATA (ATA/150) with support for RAID 0, 1, 5, and 10. Includes 64 MB of integrated ECC SDRAM memory and supports up to 40 logical drives from the 4 physical drives.
- SATA 150-6: Similar to the 150-4, with support for 6 physical drives.
- SATA 300-8X: 8 port adapter with SATA II support and offering RAID levels of 0, 1, 5, 10, and 50.
- SATA 300-4XLP: Low profile, extended length 4 port adapater with SATA 1.5 Gb/sec and 3 Gb/sec drive mode support and support for RAID 0, 1, 5, 10, and 50
- SATA 300-8XLP: Low profile 8 port adapter with SATA II support and offering RAID levels of 0, 1, 5, 10, and 50.
- SCSI 320-0: Zero-channel card converts the motherboard's own SCSI controller into a RAID controller. Supports up to 40 logical drives per controller.
- SCSI 320-0X: PCI-X version of the 320-0.
- SCSI 320-1: Single channel SCSI (Ultra320) adapter.
- SCSI 320-1LP: Single channel SCSI (Ultra320) adapter, with the internal connector mounted vertically
- SCSI 320-2: Dual channel Ultra320 (PCI 2.2).
- SCSI 320-2E: Dual channel PCI Express card with support for RAID levels 0, 1, 5, 10, and 50
- SCSI 320-2X: Dual channel PCI-X SCSI card.
- SAS 8308ELP: Low profile 8 port (SAS/SATA) PCI Express card with support for RAID 0, 1, 5, 10, 50.
- SAS 8344ELP: Low profile PCI Express card supports four internal and four external SAS/SATA II drives. Supported RAID levels are 0, 1, 5, 10 and 50.
- SAS 8408E: 8 port Serial Attached SCSI card supports SAS, SATA II, or any combination of the two.
- SAS 8480E: w/2 x4 external SAS connectors for external storage. When used with SAS expanders, the 8480E can support up to 255 SAS or SATA II disk drives.
- SAS 8704EM2/8708EM2: Two of the three newest entries in the family. The 8704/8708EM2 are MD2 low profile x8 PCIe cards with 4 and 8 internal connect SAS ports, respectively. These and the 8880EM2 below include support for RAID 6 as well as battery backup options.
- SAS 8880EM2: The other new card, also an MD2 low profile x8 PCIe card with 8 external connect SAS/SATA ports.
