Model Variants

AlphaServer ES40 systems are offered in two models. The

entry-level model provides connectors for four DIMMs on

each of the memory motherboards (MMBs) and connectors for

six PCI options on the PCI backplane.

Model 1 Model 2

To upgrade from Model 1, you replace the PCI backplane and

the four memory motherboards. A Model 2 system has eight

DIMMs on each MMB (32 total) and 10 PCI slots.

System Packaging

All system variants use the same chassis, with space for two

disk cages in the front. Each cage holds up to four 1.6-inch

Ultra2 SCSI disks.

The chassis has a compartment for the CPUs and memory and

another one for the PCI I/O cards. The control panel, CD-ROM

and floppy drives, and two additional removable media bays are

in the front, along with space for up to two disk cages. The

power supplies are in the rear.

Chassis, Pedestal View

Additional storage is available in the pedestal enclosure. The

chassis is mounted over a box that can house up to three

StorageWorks shelves (two in the front and one in the rear).

Chassis, Tower View

In the tower enclosure, the chassis is rotated 90 degrees, with

the control panel and removable media bays keeping their

same horizontal position as in the pedestal/rack system.

Rackmount Chassis

When installed in a cabinet, the chassis has the same

orientation as that used in the pedestal. The chassis can be

mounted in the 67-inch or 79-inch M-series cabinet, which is a

19-inch wide RETMA cabinet. Each system requires 14

inches (8U) of vertical space. With the maximum number of

systems in a cabinet (four), there can be two StorageWorks

shelves. When the maximum number of disks is desired (six

shelves), there can be three systems. (These numbers are for

the H9A15 79-inch cabinet.)
