To manage blade servers, you can use the BladeCenter S system, Serial over LAN,
or the serial pass-thru module.
Deployment of blade servers
Plan to meet at least the minimal hardware and software requirements for
deploying blade servers, firmware, device drivers, and operating systems.
Hardware considerations for blade servers
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.
v Additional internal hard disk drives. Some blade servers support IDE hard disk
v Memory module options to increase the amount of memory in your blade

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.
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.
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.
