File deduplication
File deduplication is supported but is not enabled by default. Enabling this feature requires knowledge of
capacity and storage requirements.
Block compression
Block compression is supported but is not enabled by default. Enabling this feature requires knowledge of
capacity and storage requirements.
External NFS and CIFS access
Vblock System 240 presents CIFS shares and NFS file systems to internal and external clients. CIFS
shares and NFS file systems are connected to both internal virtual machines and to external client
systems at the same time on a single share system. VMware NFS datastores are connected to both
internal and external hosts, but not at the same time. If both internal and external NFS datastores are
required, two NFS file systems must be created; one for internal hosts and one for external hosts.
Snapshots
For block storage snapshots, EMC SnapView is supported. This software provides local block replication
using snaps and clones without the extra cost of the optional EMC RecoverPoint Appliances. This
software is included in the EMC VNX Local Protection Suite.
For NAS file system snapshots, EMC SnapSure is supported. It is included in the EMC VNX Local
Protection Suite.
EMC VNX Snapshots creates point-in-time data copies.
Replicas
For Vblock System NAS configurations, EMC VNX Replicator is supported. This software can create local
clones (full copies) and replicate file systems asynchronously across IP networks. EMC VNX Replicator is
included in the EMC VNX Remote Protection Suite.
Scaling up storage resources
This topic describes the RAID packs option and the disk array enclosures option for scaling up storage
resources.
To scale up storage resources, you can:
