1.5.9 Disk features
The PS700 blade servers has two disk bays:
In the first bay it can have one 2.5 inch SAS HDD
In second bay it can have one 2.5 inch SAS HDD
The PS701 blade servers has one disk bay. In this bay it can have one 2.5 inch SAS HDD.
The PS702 blade servers have two disk bays (one on each of the blade):
On the base card it can have one 2.5 inch SAS HDD.
On the expansion unit it can have one 2.5 inch SAS HDD.

1.5.10 Standard onboard features
In this section, we describe the standard on-board features.
Service processor
The service processor (or flexible service processor, FSP) is the main integral part of the
blade server. It monitors and manages system hardware, resources, and devices. It does the
system initialization, configuration, and thermal/power management. It takes corrective action
if required.
The PS700 and PS701 have only one service processor. The PS702 blade server has two
FSPs (one on each blade). However, the second service processor is only in IO mode and is
not redundant to the one on the base blade.
For more details about service processors, see 2.10, “External disk subsystems” on page 68.
Host Ethernet Adapter (HEA)
The integrated IO Hub provides two 1 GB Ethernet ports also called HEAs (host Ethernet
adapters). HEA is part of the Integrated Virtual Ethernet subsystem (IVE). Each HEA has their
own MAC address and can have a maximum of 16 logical ports. These logical ports can be
