ABC.com’s storage environment is organized into four single-director fabrics. The directors are
MDS-9509s with 64 switch ports in each. No more than 70% of available ports are in use.
The customer needs hosts in each fabric to access storage in the other three fabrics. It is
acceptable for host-to-storage traffic to traverse up to one hop.

What is the least disruptive SAN solution that you should consider?

ABC.com currently has a large storage install base with many hosts. A large number of the hosts

ABC.com would like to use Replication Manager along with a Celerra solution. They have asked if
there are any limitations when accessing the replica. The replica of the destination LUN is
designed to be used for content distribution, data mining, testing, or other applications that offload

Which consideration should be identified to the customer?

ABC.com has implemented a second Brocade director into their environment. They have moved
several hosts and one of their two storage arrays onto the new director. When a large batch cycle
was run, the customer experienced queuing on the directors when previously there was none.
The customer discovered the following during their analysis of the issue. The hosts running the
batch cycle used storage from both arrays.
The only LUNs having problems came from the array attached to the new director. When the
batch process was re-run with all LUNs made available through the original director, no problems

were encountered.
What would you recommend to solve the performance problem?

Using SAN Copy, a source Windows LUN of 100 GB has been copied to a 200 GB target LUN.
