A customer storage infrastructure consists of eight HP StoreVirtual 4000 nodes in a cluster,
connected to an HP 2910-24G al network environment.
Server virtualization is done using VMware vSphere 5.1 on six hosts across two sites.
Which drawbacks must the customer consider when upgrading the solution? (Select two.)

A.
When adding more nodes in the cluster, additional 1Gb network ports have to be added in each
node.

B.
When using more than eight nodes in a cluster, a 10 Gb connection is recommended.

C.
When upgrading to VMware version 5.1, the iSCSI multipathing driver has to be configured.

D.
When using a server across the sites, VMware Site Recovery Manager is needed.

E.
When using 10 Gb the customer has to implement new network switches.

Explanation:
Recommended network switches for HP StoreVirtual 4000 Storage
HP Networking has an extensive portfolio of Ethernet switches that are ideally suited for iSCSI
deployments.
These switches are designed to deliver high-performance, low-latency, and wire-speed Layer 2 to
4 network services. HP Networking top of rack series of switches offer unmatched combination of
1GbE and 10GbE ports density, high availability architecture, Intelligent Resilient Framework (IRF)
technology as well as a full range of Layer 2 and or Layer 3 features depending on switch
selection. These switches are built to support open and industry-standards networking protocol.
These switches can be deployed within the network core or as a highperformance switch in the
convergence layer or network edge of SMB and enterprise networks. Listed below is a selection of
recommended top of rack models. These are the 3800, 5830, 5920, and 6600 series.
Another recommended switching platform is the HP
Networking 2920 series, to learn more visit hp.com/go/networking.

Recommended switch infrastructure for an HP P4000 SAN
HP does not recommend any particular switch for use with HP P4000 SANs. However, there is a
set of minimum switch capabilities that make building a high-performance, high-availability storage

network a relatively easy and cost effective task.
The following are three commonly recommended HP switches, but ultimately you will need to
follow the recommended switch capabilities in Table 1 below which provides guidance forgeneral
switch selection based on your specific needs. As a rule of thumb, any enterprise-class managed
switch typically has the capabilities required for most customer installations.
• HP E2910 al Switch Series (10/100/1000Base-T & 4 x optional 10GbE)
• HP A5810-48G Switch (10/100/1000Base-T & 2 x 10GbE)
• HP E6600 Switch Series (10/100/1000Base-T and 10-GbE SFP+)
