5 Storage

The PowerEdge VRTX platform provides comprehensive, shared internal storage options, including
several drive types to choose from. VRTX supports up to 48TB of internal, low-latency storage.
All four server nodes have access to the full storage space. Each server node sees the storage as its
own singular storage pool. You can assign virtual disks to single server nodes or across server nodes
(with clustering) using the CMC.

Infrastructure

One of the key differentiators for VRTX is the integrated shared storage. Virtualization support at
remote sites requires shared storage for VM migration. To date, shared storage solutions have been
too expensive for these applications; however VRTX is able to leverage existing PERC technology to
deliver a low-cost 6Gb/s direct-attached storage (DAS) solution and virtualization support.
The PERC provides multiple channels of virtual I/O. PCIe switches provide the ability to map virtual
functions to multiple servers through virtual PCIe hierarchies. CMC has a web interface you can use
to create maps to the servers, and create and assign corresponding virtual drives. Figure 6 shows the
Virtual Disks tab on the CMC web interface.
