Feature Description

vStorage API for Array

Integration (VAAI)

enhancement

NFS snap-on-snap of VMDK files to one level of depth. For example,. fast clone of a fast

clone that is a second level clone of a base image of a virtual machine

Data-in-place block

compression

When compression is enabled, thick LUNs are converted to thin LUNs and are

compressed in place. RAID group LUNs are migrated into a pool during compression.

There is no need for additional space to start compression. Decompression temporarily

requires additional space since it is a migration and not an in-place decompression.

Compression for file/

display compression

capacity savings

Two available types of file compression are:

•

Fast compression (default)

•

Deep compression (up to 30% more space efficient, but slower and with higher CPU

usage)

Displays capacity savings due to compression to inform the user of savings from

compression (separate from savings due to thin LUNs), so that users can do a cost/benefit

comparison (space savings versus performance impact).

EMC VNX snapshots EMC VNX snapshots are for storage pools only, not for RAID groups. Storage pools can

use EMC SnapView snapshots and EMC VNX snapshots at the same time.

Note: This feature is optional. Both types of snapshots have seamless support. VCE

relies on guidance from EMC best practices for different use cases of EMC

SnapView snapshots versus EMC VNX snapshots.

Correlated statistics

enhancements

Correlated statistics capture real-time statistics about I/O activity on EMC VNX file storage.

CIFS and NFS statistics are correlated by client IP addresses, CIFS/NFS users, and disk

volumes.

The following indexes are added to the correlated statistical data:

•

NFS groups (lists the 20 most active NFS groups for an X-Blade)

•

NFS users (lists the 20 most active NFS users for an X-Blade)

•

NFS file systems (lists the top 20 NFS operations per client per file system. This can

be correlated by file system, client IP, or NFS operation).

CIFS statistics/file system statistics:

•

Files in a quota tree (lists the 20 most active files in each quota tree)

•

Files in a file system (lists the 20 most active files in each file system).

NFS statistics: NFS exports (lists the 20 most active exports on an X-Blade)

NFS groups:

•

CIFS servers (lists the top 20 most active CIFS servers on an X-Blade)

•

CIFS clients (by host name)

Hardware features

VCE implements the following EMC VNX features in Vblock 240:

•

Dual 10 Gigabit Ethernet Active Twinax IP IO/SLIC between the X-Blades and Cisco Nexus

5548UP Switches
