RAID arrays and logical drives to span the channels within a single adapter. This
allows for larger logical drive capacities and even greater performance levels.
As a summary, the following is a list of the capacities of RAID arrays and logical
drives as supported by the ServeRAID family:
• Up to 15 drives per channel (depending on the capabilities of the disk
enclosures used)
• RAID arrays spanning multiple channels on the same adapter
• Up to eight RAID arrays per adapter
• Up to 16 hard disks per RAID array (for stripe sizes of 8 KB or 16 KB) and up
to eight hard disks per RAID array (for stripe sizes of 32 KB and 64 KB)
• Logical drives of RAID-0, RAID-1, RAID-1 enhanced, RAID-5, and RAID-5
enhanced configuration
• Up to eight logical drives per adapter
• Up to eight ServeRAID adapters per server (depending on the capabilities of
the server)
• Operating system partitions up to 2 TB each (depending on physical disk
sizes)
• The operating system boot partitions can only be up to 2 GB if migrated from
Streaming RAID or PCI RAID adapters.
• Non-disk devices are not supported by the ServeRAID-3HB, 3H, and 3L
adapters.
Note: Devices using multiple SCSI logical unit numbers (LUNs) are not supported
by the ServeRAID adapters.
2.2.2 SCSI channels and connectors
The ServeRAID family of adapters offers Ultra2, Ultra, or Fast/Wide SCSI
channels, depending on the model selected:
• The ServeRAID-3HB and 3H adapters have three Ultra2 SCSI channels
• The ServeRAID-3L adapter has one Ultra2 SCSI channel
The ServeRAID-3HB and 3H adapters provide three Ultra2 SCSI channels
through one internal and two external connectors, as shown in Figure 13. The
internal connector is a standard 68-pin SCSI-2 F/W connector and the external
connectors are standard .8 mm Very High Density Connector Interface (VHDCI)
connectors. The connectors support both single-ended and low voltage
differential signaling (LVDS) SCSI interfaces.
