You are an administrator for ABC.com. ABC.com currently has two existing DS-16B switches in
two separate SANs. The hosts consist of two AIX servers and five Windows servers. Each server
currently has two HBAs, one for the storage SAN and one for the tape backup SAN. The AIX is a
mission critical environment, but is rarely changed. Servers might need to be added during
business hours, because the Windows environment is expected to triple in size over the next few
months. The storage array has already been upgraded to a new CX500. ABC.com wants to
replace the switches with 2Gb technology, to support the CX500 and provide high availability. The
SAN architecture must also be scalable to accommodate future growth. ABC.com has also been
experiencing the following problems:
Several AIX outages related to the SAN. An AIX server disruption during updates to the SAN
fabric while adding new windows serversA switch port failure on an AIX host connection. After
moving the fiber cable to an open port on the switch, all the AIX device IDs changed Of the
following, which configuration would satisfy ABC.com high availability requirements and eliminate
the AIX problems?

A.
PowerPath Utility Kit for Windows hosts. Two DS-32M2 redundant fabrics for storage. One
additional HBA for dedicated tape backup. A single DS-24M2 to support the tape and the AIX
servers

B.
PowerPath Enterprise licensing for all hosts. Two Cisco MDS-9140 redundant switches. Create
separate VSANs for the Windows, AIX and Tape backup. Configure static domain IDs and
persistence on the switches

C.
PowerPath Enterprise licensing for all hosts. Two DS2-4M2 switches configured as redundant
SAN fabrics for storage. Two additional 2Gb HBAs per server for storage. ISL the existing DS-16B
switches for a dedicated Tape SAN using one existing HBA per host

D.
PowerPath Basic for Windows hosts. Two DS-4100Bs populated with 24 ports each configured
as redundant fabrics. Replace all HBAs with new 2Gb HBAs. Configure persistent binding on the
AIX hosts
