15,000 RPM and the converged tray design are supported. To configure RAID-1, a ServeRAID adapter is required. The ServeRAID-4Mx and ServeRAID-4Lx can be used for connection to the hot-swap backplane of the internal drive bays. Important: The ServeRAID-4H is supported in the x440 when used for external storage enclosure connectivity only, because the adapter is too high for the 4U chassis when the internal SCSI connector is in use. Note: The x440 has two cables pre-installed for use with the internal drive bays, but one is not connected. The shorter cable is initially connected from the onboard SCSI to the drive backplane. When you install a ServeRAID adapter for use with the internal drive bays, you will need to disconnect this cable and connect both ends of the longer cable.

15,000 RPM and the converged tray design are supported. To configure RAID-1,

a ServeRAID adapter is required. The ServeRAID-4Mx and ServeRAID-4Lx can

be used for connection to the hot-swap backplane of the internal drive bays.

Note:

The x440 has two cables pre-installed for use with the internal drive bays,

Typically the x440 will be attached to an external disk enclosure for data storage

requirements. Some of the supported IBM storage options include:

SCSI RAID adapters and storage enclosures

Fibre Channel adapters and Storage Area Networks (SANs)

Network Attached Storage (NAS)

SCSI over IP (iSCSI)

xSeries storage solutions

This section discusses some of the available xSeries storage solutions and

related technologies, as well as tape backup and performance considerations.

ServeRAID with external storage enclosures

The current ServeRAID-4 family of adapters includes the ServeRAID 4H, 4Mx

and 4Lx. These 64-bit, Active PCI controllers include advanced features such as

Logical Drive Migration, nine RAID levels including RAID 1E, 1E0 and 5E, as well

as adapter and cluster failover.

ServeRAID-4H features four Ultra160 SCSI channels, 128 MB of removable

battery-backed ECC cache memory, and an IBM PowerPC 750 processor

onboard. Up to 56 Ultra160 and Ultra2 SCSI devices are supported. (Using

73.4 GB hard disk drives produces 4.11 TB capacity per adapter.)

ServeRAID-4Mx features two Ultra160 SCSI channels, 64 MB of

battery-backed ECC cache memory, and an Intel i80303 processor. Up to 28

Ultra160 and Ultra2 SCSI devices are supported.

Important:

The ServeRAID-4H is supported in the x440 when used for

external storage enclosure connectivity only, because the adapter is too high

for the 4U chassis when the internal SCSI connector is in use.
