Which statement is true about this implementation plan?

You are creating and implementation plan with the system engineers for a newly designed
infrastructure solution using HP StoreVirtual 4330 Storage width VMware vSphere. The
proposed backup strategy includesHP Data Protector using the VMware vStorage API for
Data Protection on a native Windows 2008 R2 host. AnHP StoreEver MSL4048 Tape Library
is directly attached to the backup server.
Which statement is true about this implementation plan?

A.
MS MPIO should be recommend for the solution

B.
The iSCSI network switches should use Spanning Tree

C.
A 10 GB NIC is required for the backup host

D.
The MSL4048 has to be connected redundantly to the Windows server

Explanation:
EBS features and benefits
EBS is a complete backup and restore solution featuring HP Tape Storage & Media (ESL Eseries, EML Eseries, MSL, Virtual Library Systems, and Autoloaders), including a variety of
servers, operating systems, host bus adapters, switches, disk arrays, and software. It is a

single point of reference for the latest support information found in the EBS Compatibility
Matrices which contain all the solution interoperability and device compatibility details
Supported topologies:
Serial-attach SCSI, Direct-attach SCSI or Direct-attach SAS, Point-to-point, Switched fabric
Direct-attach SCSI
Direct-attach SCSI (DAS) is the most common form of attachment to both disk and tape
drives. Direct-attach SCSI allows a single server to communicate directly to the given target
device over a SCSI cable. These configurations do not allow for multi-hosting a single target
device, because the target device is dedicated tothe server.
Why not arbitrated loop? Any disruption of the loop causes disruption in the backup and
backup jobs fail Recommended uses for HP DSM for MPIO:
• For maximum possible performance for specified configurations.
• With Multi-Site SAN storage clusters, the HP DSM for MPIO with site preference is
recommended, particularly if the inter-site link is significantly slower than local access. This
configuration will ensure that reads are performed with a local replica when one is available.
This is particularly useful for Microsoft clusters where a Microsoft cluster node is on each
side of the inter-site link.
