Your customer needs to consolidate data and add additional block-based storage to their man document management application. They nave five standalone servers with 10Gb networking Which storage technology should you recommend?

The customer's key requirement is for block-based storage that can be consolidated and shared across five servers. A Storage Area Network (SAN) is the only technology listed that provides block-level data access over a dedicated network. The existing 10Gb networking infrastructure is ideal for implementing an iSCSI SAN, which would present shared storage volumes (LUNs) to the servers. The servers' operating systems would see this storage as locally attached block devices, fulfilling the core requirement for the document management application.

A. Network File System: This is a file-level sharing protocol, not a block-based storage technology, which fails to meet the primary technical requirement.
C. Direct Attached Storage: This storage is connected to a single server and cannot be shared or consolidated among multiple servers as required.
D. Network Attached Storage: This provides file-level access (using protocols like NFS or SMB) over a network, not the required block-level access.

Module 6: Introduction to HPE Storage

"Storage Area Network (SAN)" section: This section explicitly defines a SAN as a high-speed network that connects servers to shared pools of block-level storage. It details how servers access this storage as if it were a locally attached drive

which directly supports the chosen answer.

Module 6: Introduction to HPE Storage

"Network Attached Storage (NAS)" section: This part of the guide defines NAS as a file-level storage architecture

contrasting it with the block-level access of a SAN. This confirms why option D is incorrect.

Module 6: Introduction to HPE Storage

"Direct Attached Storage (DAS)" section: This section describes DAS as storage connected to a single computer that is not accessible to other computers over a network

confirming why option C is unsuitable for a consolidated environment.
