Scenario
Following the merger of two financial companies, management is considering combining the two
distinct customer call centers into a single physical location. In addition to the overall call center
headcount increasing by 30%, the support for two distinct customer bases presents the potential
of having two different desktop PCs on the desk of each call center employee. Instead of
correspondingly increasing IT support headcount to manage the single, larger call center and call
center infrastructure, management believes they can reduce the required time to support call
center operations by 40% if they employ virtual desktop technology.
An initial assessment has identified the need for a centralized storage solution that could support
500 virtual desktops running a variety of applications that can scale quickly to accommodate an
expected increase in call center staff. The customer is already an HP Blade System customer
using HP Virtual Connect Flex-10.
Some of the additional business criteria identified in customer planning interviews includes:
Use client virtualization for the desktops.
Achieve the highest possible density and performance for the virtual desktops, but keep the
virtual desktop storage traffic off the network due to a current, existing limitation of only 1GbE.
Do not use standalone, network-attached storage.
Limit the impact of additional rack space.
Minimize the risk of additional help-desk tickets.
Present multiple solutions, prioritized with a recommendation.
Refer to the scenario.
Your proposed design includes a VMware View environment using HP storeVirtual 4800. What
has to be considered when designing a solution?

A.
Offer asynchronous replication to keep the virtual desktops up and running in case of a
component failure.

B.
Use VMware View provisioning servers outside the blade to minimize LAN traffic to the
enclosure.

C.
Avoid boot storms and insufficient response times during critical shift change hours.

D.
Include HP virtual Connect FlexFabric to connect to the HP StoreVirtual environment.

The customer is already an HP Blade System customer using HP Virtual Connect Flex-10
(Not It makes no sense answer D), HP Virtual Connect Flex-10 10Gb Ethernet Modules for cClass BladeSystem simplify networks by reducing cables without adding switches to manage;
They provide 4:1 consolidation of interconnect equipment: Each VC Flex-10 module can replace
up to four Ethernet switches supporting data and iSCSI storage traffic.
A “boot storm” is the tremendous performance drain experienced when hundreds or thousands of
users logon at, or near, the same time in VDI environments. The drag on network throughput, host
performance and SAN I/O can be devastating to an unprepared VDI installation. Some of the
pressure can be eased by building the environment according to some best practices laid out by
virtualization vendors. But, there are a few areas that you might not have considered when
constructing your VDI infrastructure.
