SK0-004 · Question #865

An administrator is adding NAS-based storage to a server. Which of the following strategies will allow users to see BEST performance with this new NAS storage?

The correct answer is C. Connect server to NAS storage using two teamed 1 Gb NICs. NAS communicates over standard Ethernet using file-level protocols, so NIC teaming on the server is the correct way to maximize bandwidth and redundancy to that storage.

Why each option

NAS communicates over standard Ethernet using file-level protocols, so NIC teaming on the server is the correct way to maximize bandwidth and redundancy to that storage.

AConnect server to NAS storage using two redundant HBAs.

HBAs (Host Bus Adapters) connect servers to Fibre Channel or iSCSI SAN storage, not to NAS devices, which use standard Ethernet NICs.

BConnect server to NAS storage using two redundant SCSI controllers.

SCSI controllers manage direct-attached storage (DAS) and have no role in connecting a server to NAS storage over an IP network.

CConnect server to NAS storage using two teamed 1 Gb NICs.Correct

NAS devices use file-sharing protocols such as NFS or SMB/CIFS transported over standard TCP/IP Ethernet, meaning network bandwidth directly governs storage throughput. Teaming two 1 Gb NICs aggregates the links to an effective 2 Gbps while also providing failover redundancy, directly improving both throughput and availability. Because NAS is a network-layer solution, increasing NIC bandwidth is the appropriate performance lever.

DConnect server to NAS storage using two redundant fabric switches.

Fabric switches are Fibre Channel SAN infrastructure components and are not relevant to NAS environments, which rely on standard Ethernet switching.
