An organization plans to build a cloud using some of the existing data center infrastructure. Specifically, they want to use the existing FC storage infrastructure to support cloud hosts. However, they want to logically separate the cloud storage traffic from the existing data center storage traffic within this infrastructure.
Which mechanism can be used to meet this requirement?
A. MPIO
B. VLAN
C. VSAN
D. Masking
Correct Answer: D
Explanation/Reference:
The use of VSANs allows the isolation of traffic within specific portions of the network. If a problem occurs in one VSAN, that problem can be handled with a minimum of disruption to the rest of the network. VSANs can also be configured separately and independently.
Note: Virtual storage area network (VSAN) is a collection of ports from a set of connected Fibre Channel switches, that form a virtual fabric. Ports within a single switch can be partitioned into multiple VSANs, despite sharing hardware resources. Conversely, multiple switches can join a number of ports to form a single VSAN.
Incorrect:
Not A: Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop multipath solutions that contain the hardware-specific information needed to optimize connectivity with their storage arrays.
MPIO is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached SCSI (SAS) interfaces in Windows Server® 2008, Windows Server 2008 R2 and Windows Server 2012.
Not D: Logical Unit Number Masking or LUN masking is an authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts. LUN masking operates at Layer 4 of the Fibre Channel protocol.
