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

2 EVA8x00 conﬁgura tions

This chapter discusses the standard EVA8x00 conﬁgurations. Each section describes the placement of

HSV controllers, drive enclosures, enclosure address bus shelf ID expansion cables, and copper Fibre

Channel cables.

NOTE:

The conﬁgurations described in this guide are the preferred conﬁgurations. Other conﬁgurations may be

used, but they should conform to the following:

• Disk enclosures should be balanced across the two back-end loop pairs.

• Use of enclosure ID 7 for disk enclosures is not a llowed.

2C2D conﬁgurations

There are two 2C2D conﬁgurations: the Storage-Centric (Figure 7) a nd the Multi-Product (Figure 9). Each

conﬁguration provides a maximum storage capacity of 8.4 TB and can contain a maximum of 28 disks.

These conﬁgurations are available in a 42U rack and have two HSV210-A/B controllers and two d rive

enclosures. The Storage-Centric con ﬁgura tion can be expanded (by a dding drive enclosures) while

remaining online. The Multi-Product more easily allows mu ltiple products to be racked with the EVA, but

can only b e expanded by powering it down to make these expansion modiﬁcations.
