3.1.2 MegaRAID SATA 300-4ELP and SATA 300-8ELP Storage Adapters
The MegaRAID SATA 300 PCI Express storage adapters are intelligent
RAID controllers that provide four or eight Serial ATA ports. The SATA
300-4ELP and SATA 300-8ELP are low-profile cards. The SATA 300-
4ELP RAID controller has four ports and supports RAID levels 0, 1, 5,
and 10. The SATA 300-8ELP RAID controller has eight ports and
supports RAID levels 0, 1, 5, 10, and 50.
The SATA 300-4ELP and SATA 300-8ELP storage adapters do the
following:
•
Supports four or eight Serial ATA ports:
– Uses differential signaling
– Transfers data in frames
– Supports Serial ATA power management
– Complies with the PCI Express Specification, Revision 1.0a; is
backward-compatible with previous versions of the PCI Express
specification
Note: The board length for the SATA 300-8ELP storage adapter
does not meet the specification; it is slightly longer than the
specification.
•
Supports a PCI Express interface:
– Supports a dedicated PCI Express bus
– Functions in a x4 or greater PCI Express slot
– Supports transfer rates of up to 2.5 Gbits/s per lane
– Complies with the PCI Express Specification, Revision 1.0a
•
Supports native command queuing, which allows the physical drives
to prioritize data requests by multiple processors, in order to
maximize throughput
