Configuration Tips for the PC Server 3519
Configuration Tips for the PC Server 3519
- You must use the Fast/Wide Enhanced Repeater (card part number 07L8392) provided in option Part Number 94G7585.
The older model SCSI repeater (option Part Number 94G5565) is not supported in cluster configurations.
- Before you install an Enhanced SCSI Repeater, be sure to review the documentation provided with the
repeater and verify that its jumpers are set properly for your specific configuration.
- Before you install hot-swap drives, be sure to review the documentation provided with the enclosure
and verify that the jumper settings on the backplane are set properly for your specific environment.
As shipped, the SCSI ID jumper (J12) is set for HI addressing and reverse IDs, which results in SCSI ID
assignments of 13 to 8 in bays 4 through 9 respectively.
- Each ServeRAID adapter supports up to eight logical drives.
If a failure occurs, the remaining ServeRAID adapter will need to support its own logical drives and the logical drives of its counterpart
in the failing server.
Therefore, the total number of shared logical drives for each set of ServeRAID adapters must not exceed eight.
A good way to ensure that you do not exceed this limit would be to define no more than four logical drives for each ServeRAID adapter.
- With the ServeRAID II adapter, you can set the stripe-unit size to 8 K (the default), 16 K, 32 K, or 64 K.
After you set a stripe-unit size and store data on the logical drives, you cannot change the size
without destroying data in the logical drives.
Both adapters in a pair must use the same stripe-unit
size.
- When the stripe-unit size is set to 8 K or 16 K, the maximum number of physical hard disk drives
in an array is 16.
- When the stripe-unit size is set to 32 K or 64 K, the maximum number of physical hard disk drives
in an array is eight.
- When using the Vinca High Availability for NetWare program, refer to the NetWare documentation for
information about calculating the amount of system memory needed to support the number and
capacity of hard disk drives you intend to install.
