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 includes HP Data Protector using the VMware vStorage API for Data Protection on a native Windows 2008 R2 host. An HP 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
Correct Answer: A

EBS features and benefits
EBS is a complete backup and restore solution featuring HP Tape Storage & Media (ESL E- series, 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 to the 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.
