ABC.com has 35 UNIX servers that use a combination of direct-attached storage and a small SAN
storage system that supports 10 servers. The SAN provides single port access to the servers.
The EMC sales team would like to displace the current SAN storage vendor and increase the
utilization of SAN storage for this customer. The team intends to propose redundant fabrics and
the use of PowerPath. You need to determine the number of HBAs that the customer will require
in each server.
