Internal Storage - IBM BladeCenter PS700 Technical Overview And Introduction

You can establish up to 20 separate Web-interface, Telnet, or SSH sessions with a
BladeCenter AMM. For a BladeCenter unit, this step enables you to have 14 simultaneous
SOL sessions active (one for each of up to 14 blade servers) with six additional CLI sessions
available for BladeCenter unit management.
With a BladeCenter S unit you have six simultaneous SOL sessions active (one for each of
up to six blade servers) with 14 additional CLI sessions available for BladeCenter unit
management. If security is a concern, you can use Secure Shell (SSH) sessions, or
connections made through the serial management port that is available on the AMM, to
establish secure Telnet CLI sessions with the BladeCenter management module before
starting an SOL console-redirect session with a blade server.
SOL has the following requirements:
An Ethernet switch module or Intelligent Pass-Thru Module is installed in bay 1 of a
BladeCenter
SOL is enabled for those blades that you want to connect to with SOL.
The Ethernet switch module must be set up correctly.
For details about setting up SOL, see the BladeCenter Serial Over LAN Setup Guide, which
can be found at the following Web page:
http://www.ibm.com/support/docview.wss?uid=psg1MIGR-54666
This guide contains an example of how to establish a Telnet or SSH connection to the
management module and then an SOL console.

2.9 Internal storage

PS700, PS701 and PS702 blades use an integrated SAS controller. The controller's PCI-X
interface to the GX+ multifunctional host bridge chip is 64 bits wide and operates at 133 MHz.
This controller provides ports for the internal drives, and ports through the 3 Gb SAS
Passthrough Expansion Card to the BladeCenter SAS switch modules. The SAS controller
ports used for the internal disk drives can support a single 2.5" SAS hard disk drive (HDD) at
each DASD bay location, as shown in Figure 2-20 on page 66, Figure 2-21 on page 66. and
Figure 2-22 on page 67.
Note: Solid state drives (SSDs) are not supported.
