Chapter 1: Introduction
Details on installation of memory modules into the SBA-7222G-T2 blade module are
found in Chapter 3: "Setup and Installation" on page 3-1.
Storage
The SBA-7222G-T2 blade module can have four 2.5" SATA (Serial ATA) hard disk drives
in front-mounted easy removable carriers, two for each node. See Chapter 3: "Setup
and Installation" on page 3-1 for storage installation details.
Density
A maximum of ten blade modules may be installed into a single blade enclosure with
two nodes. Each blade enclosure is a 7U form factor, so a standard 42U rack may
accommodate up to six enclosures with 60 blade modules, two nodes per module, or
the equivalent of 120 1U servers. With the inclusion of six CMM modules, twelve Gigabit
Ethernet switches and six InfiniBand switches, this would occupy up to 144U space in a
conventional 1U dual processor server configuration.
Figure 1-1 displays a view of a full rack with six blade enclosures in it, each with ten
blades to an enclosure.
