What is a benefit of VNX FAST Cache?

A customer has an application requirement of 3000 IOPS with a 60:40 read/write ratio and 4.85 TB
storage capacity. The I/O is small-block random. The customer is concerned about cost. You
propose a VNX with 300 GB 10K SAS drives.
If spare drives are not included, which configuration minimizes costs while adhering to EMC best
practices?

Which subnet range should not be used for VNX iSCSI ports because of the static management
service ports?

Which action is no longer necessary because of the host write throttling function on the VNX with
MCx?

A VNX Storage Pool holds only thick LUNs. The properties page of that Storage Pool shows 500
GB free space. An admin attempts to create a 490 GB thick LUN, but the operation fails.

Why?

A customer is using a VNX with tiered storage pools. They would like to maximize capacity for
their NL-SAS tier. Following EMC best practices, which RAID configuration would you recommend
for this customer?

A customer has a Microsoft Server 2008 R2 using VNX block storage. They are looking at
multipathing options to ensure failover and load-balancing. Following the EMC best practices,
what would you recommend?

A solution has been designed for a customer in which several ESX servers are connected to a
VNX array through iSCSI. The customer created two separate networks to isolate the iSCSI traffic.
One set of ESX and VNX ports is on a 192.168.3.x/16 network while the other set is on a
192.168.4.x/16 network.
While performing several tests, the customer sees that some ports are not working correctly. What
is causing this issue?
