You can order optional hardware for blade servers that will be
installed in a BladeCenter S system.
The optional hardware available depends on the blade server that you are installing.
You can choose to add the following types hardware options to a blade server
that will be installed in a
BladeCenter S system.
See the documentation for the blade server that you are installing for the
specific options that are available.
- Additional internal hard disk drives.
Some blade servers support IDE hard disk drives,
some support SCSI drives, and others support internal SAShard disk drives.
- Memory module options to increase the amount of memory in your blade server.
When you install memory, you must install a pair of matched dual inline memory
modules (DIMMs).
- SAS expansion card
option to enable the blade servers to communicate with either the SAS RAID controller module or the SAS connectivity module and the integrated
shared storage.
- Up to four microprocessors. With two microprocessors, your blade server
can operate as a symmetric multiprocessing (SMP) server. To ensure proper
server operation when you install an additional microprocessor, use microprocessors
that have the same cache size and type, and the same clock speed. Internal
and external clock frequencies must be identical.
Note: Some
blade servers, such as the IBM BladeCenter LS41, support up to four microprocessors
with the addition of a multiprocessor expansion unit. With the addition of
the multiprocessor expansion unit, the blade server will occupy two blade
server bays.
- A SCSI storage expansion unit for using SCSI hard disk drives with
your blade server. With the SCSI storage expansion unit, you can install up
to two 1-inch (26 mm) slim-high, 3.5-inch, hot-swap SCSI hard disk drives.
If you install the SCSI storage expansion unit, the blade server occupies
two to three blade server bays, depending on the blade server.
- The PCI I/O expansion unit adds additional adapter-based functions to
your blade server. The PCI I/O expansion unit allows you to add up to two
full-length, full-height PCI adapters. If you install the PCI I/O expansion
unit, the blade server occupies two to three blade server bays, depending
on the blade server.
