Server expansion capabilities
You can add up to six blade servers to the BladeCenter S chassis. Some blade
servers have connectors for additional optional devices that you can use to add
capabilities to the blade server. For example, you can connect either a storage
expansion unit or a PCI expansion unit to a blade server. Alternatively, you can
add optional I/O expansion cards to add network interfaces or storage through
I/O modules. SAS expansion cards provide access through SAS connectivity
modules or SAS RAID controller modules that are installed in I/O bays 3 and 4
to the hard disk drives in the BladeCenter S chassis.

drives. SAS RAID controller modules support the use of SAS hard disk drives
only.
SAS connectivity modules support the use of SAS or SATA hard disk

Hot-swap capabilities
Bays in the BladeCenter S chassis are hot-swappable. For example, you can add,
remove, or replace a blade server or a SAS or SATA hard disk drive without
removing power from the BladeCenter S chassis.
The midplane provides hot-pluggable connectors for the following components:
– Six blade servers
– Four I/O modules
– One advanced management module
– One serial pass-thru module
– Four power modules
– Four fan modules
– Two storage modules
– One media tray

Note:
BladeCenter S system determines the result of a power module failure.
Power modules also provide cooling fans for the storage modules. Therefore,
if you are using storage module 1, you must install power modules 1 and 2. If
you are using storage module 2, you must install power modules 3 and 4.

- Redundant high-speed serialize/deserialize (SERDES) interconnects
between blade servers and switches
- I2C communication between the advanced management module and all
modules (except blade servers)
- RS-485 (EIA 485) communication between the advanced management
module and blade servers
- Analog video connectors from the blade servers to the advanced
management module
- USB connections between the blade servers and the advanced management
module

SAS RAID controller modules in I/O module bays 3 and 4 provides support
for redundant access to the storage modules in the BladeCenter S chassis (if
both storage modules are installed).

Systems management
The advanced management module is used to communicate with the service
processor in each blade server to provide system monitoring, event recording,
and alerts. You can manage the BladeCenter S chassis, its devices, and the blade
servers remotely.

server system. It supports up to six blade servers that can share common resources,
such as power, cooling, management, and I/O resources within a single
BladeCenter S chassis. In addition, it provides support for up to twelve 3.5-inch,
hot-swappable SAS or SATA hard disk drives.
The BladeCenter S system provides the following features:
