8x00 Enterprise Virtual Array hardware configuration guide (5697-7338, February 2008)

1 EVA 4x00/6x00/8x00 hardware

This chapter discusses the ha rdware components in the Enterprise Virtual Array (EVA). The following

topics are discussed:

• Storage rack

• Fibre Channel drive enclosures

• Fibre Channel loop switches

• EVA8x00 HSV210-A/B controllers

• EVA6x00 and EVA4x00 HSV200-A/B controllers

Storage rack

Racks are available for the EVA storage system in 36U and 42U conﬁgurations. The storage rack can

hold a maximum of 12 Fibre Channel (FC) drive enclosures and two controllers.

36U rack

The 36U rack is graphite in color and 1000 mm (39.4 inches) deep. The 19–inch (482.6 mm)

industry-standard rack provides an enclosure for rack-mountable products with a height capacity of 36U.

Perforated front and back doors are included, and 36U side panels and stabilizer kits are optional.

42U rack

The 4 2U rac

k is graphite in color and 909 mm (35.8 inches) deep. The storage rack features standard

19–inch (

482.6 mm) mounting rails. The 42U rack can support Enterprise Virtual Array conﬁgurations

that incl

ude FC loop switches or expansion panels. Perforated front and back doors are included, and

42Usidepanelsandstabilizerkitsareoptional.

Fibre Channel drive enclosures

Each FC drive enclosure includes the following features:

• 3U drive enclosure

• Dual redundant, active-to-active, 2–Gbps Fibre Channel loops

• Fourteen 1–inch Fibre Channel disks per enclosure

• Dual 2–Gbps Fibre Channel I/O module—A and B

• Enhanced fault detection

• Small Form-Factor Pluggables (SFPs)

• Dual 500–W redundant hot-plug power supplies and fans

For ease of reference, the disk drives are usually referred to by their physical location in the drive bay.

Figure 1 shows the front and rear views of the FC drive enclosure and the physical location of each

drive bay.
