recommen

ded, because it provides HP with a communication path for issues and updates.

• Conﬁrm that the hardware and software components you plan to use are supported for use with

the EVA4400. Before installing your EVA4400 and before making any conﬁguration changes,

check the HP StorageWorks Enterprise Virtual Arra y compatibility reference.

• Read the

HP StorageWorks SAN design reference guide . This guide contains useful information

SAN management best practices

• Label all physical devices and cables.

•LabeleachHBAtoidentifyitsWWN.

• Label both ends of each cable with a number or color-coding scheme. Include “to” or “from”

information on each label to allow you to quickly identify each cable.

• Label each host with its name, alias, and operating system.

• Use plugs and end caps on unused device ports and cables. Never leave ports exposed.

• Draw physical and logical maps of your network.

• Topology map—Technological SAN topology and fabric interconnect scheme; including a

strategy to accommodate expansion and technological advances.

• Hardware/Device conﬁguration map—Physical layout of all network components, including

device names and aliases, the WWN and physical location of each node and device.

This information is needed when conﬁguring the storage, entering connection information,

and setting up multipathing; it is also needed for future conﬁguration changes, reference,

troubleshooting purposes, and verifying connectivity.

•Storagemap—Deﬁ nes the storage system conﬁguration and settings, such as LUN allocation

and Vraid levels.

• Zoning, path, or accessibility map—Deﬁnes the communications access settings for devices

and user ports in the SAN, including which devices are allowed to communicate with each

other and which hosts can access which LUNs.
