Which of the following options would you choose to accomplish the desired goal? (Select two. Each correct answer will present a part of the answer)

A.
A Fibre Channel (FC) disk storage subsystem that supports the Virtual Disk Service (VDS).

B.
A Fibre Channel (FC) disk storage subsystem that supports Microsoft Multipath I/O.

C.
An iSCSI disk storage subsystem that supports Microsoft Multipath I/O.

D.
An iSCSI disk storage subsystem that supports Virtual Disk Service (VDS).

E.
Configure the storage subsystem as a RAID 5 array.

F.
Configure the storage subsystem as a RAID 0 array.

Explanation:

To deploy a distributed database application on a Windows Server 2008 server and design a storage strategy with given requirements, you need to implement a Fibre Channel (FC) disk storage subsystem that uses Microsoft Multipath I/O and configure a RAID 5 array.

The fibre channel (FC) technology and FC switches between servers and storage to create a Storage Area Network (SAN). The connectivity the switches provide allows the connection of more than one server to a storage system. This reduces the number of storage systems required. This would allow a distributed database application multiple servers and design a storage strategy that allocates storage space to servers as required. Multipath I/O (MPIO) is a feature that provides support for using multiple data paths to a storage device. Multipathing increases availability by providing multiple paths (path failover) from a server or cluster to a storage subsystem.

If a server supports Microsoft Multipath I/O (MPIO), Storage Manager for SANs can provide path failover by enabling multiple ports on the server for LUN I/O traffic. To prevent data loss in aFibre Channel environment, make sure that the server supports MPIO before enabling multiple ports. (On an iSCSI subsystem, this is not needed: the Microsoft iSCSI initiator (version 2.0) that is installed on the server supportsMPIO.)
