Storage layer hardware

Storage overview

The storage layer in a Vblock System 240 consists of an EMC VNX5200 storage array.

EMC VNX series is composed of fourth-generation storage platforms that deliver industry-leading

capabilities. They offer a unique combination of flexible, scalable hardware design, and advanced

software capabilities that enable them to meet the diverse needs of today’s organizations.

EMC VNX series platforms support block and unified storage. The platforms are optimized for VMware

virtualized applications. They feature flash drives for extendable cache and high performance in the

virtual storage pools. Automation features include self-optimized storage tiering and application-centric

replication.

The storage array consists of up to five disk enclosures (DPEs and DAEs) that contain disk drives. These

connect to dual storage processors (SPs) over six GB four-lane serial attached SCSI (SAS). Fibre

Channel (FC) expansion cards within the storage processors connect to the Cisco Nexus 5548UP

switches within the network layer over FC.

Regardless of the storage protocol implemented at startup (block or unified), cabinet space can

accommodate cabling and power to support future hardware expansion for either of these storage

protocols. This arrangement makes it easier to move from block storage to unified storage with minimal

hardware changes. However, all components must fit in the single 42U cabinet.

Note: All EMC VNX components are installed in VCE cabinets, in VCE-specific layouts.
