ABC.com has approached EMC for a meeting to discuss storage consolidation. ABC.com’s
datacenter currently consists of several hundred Windows and UNIX servers. ABC.com’s
Windows environment consists of application servers, web servers, and file servers. ABC.com’s
UNIX systems are running Oracle ERM systems. Furthermore, ABC.com has two mainframes
running their inventory control system, as well as a mixture of DAS and SAN islands (Brocade
Silkworm 1GB switches) along with some old HDS connected to its mainframe that total
approximately 150TB. ABC.com is growing quickly and is searching for methods to bring
expenses under control. High availability has become a priority because of recent outages that
were caused by single points of failure in its storage infrastructure. Which components would be
most appropriate when designing the SAN?

Departmental switches, dualHBAs, dual redundant fabrics

B.
Directorclass switches, dual HBAs, dual redundant fabrics
