Creates an abstraction of the physical placement of data MetaLUNs enable quick response for additional storage Application stays online with no disruption (host-platform- dependent) Benefits of metaLUNs: Better capacity utilization from anywhere within array Lets you spread data over more spindles for better performance Includes striping capabilities for enhanced LUN expansion CLARiiON Virtual LUN Technology Moves volumes within a CLARiiON CX system without application disruption Makes management easier Tiered storage within a CLARiiON CX series system Optimize performance—up or down Use all available capacity Move to new drive technology Feature available with FLARE 16 or greater SnapView: Two Local Replication Methods SnapView is a software product for the CLARiiON AX100 and up Full Image Copy Storage-based product; uses no host cycles Provides up to 8 replicas per source – each Full image copies of production information, called BCV business continuance volumes (BCVs or clones) Logical point-in-time views of production information, called snapshots Clone SnapView Replica restores Source Return to original production data at time of split Production Can be mounted to secondary host to verify data Information consistency Snap
snapshot Logical Point-In-Time View MirrorView: Remote Replication
Mirroring between CLARiiON Bi-directional systems Remote Mirroring Storage-based; uses no host cycles Bi-directional mirroring for maximum protection
Enables complete failover of Mirror A production environment to Production remote site A Production Protects critical production information B from planned and unplanned downtime Mirror Protection from natural, mechanical, and B environmental disasters Minimizes planned downtime for equipment upgrades, disaster recovery process testing Local Remote CLARiiON CLARiiON MirrorView: Available Choices
MirrorView/Synchronous (MirrorView/S) Source Target Highest service level - No data exposure 120 Miles Maximum Limited distance (<120 Miles) Needs more network bandwidth
MirrorView/Asynchronous (MirrorView/A) Customer defined RPO Source Target (Recovery Point Objective) - Minutes to hours Unlimited Distance Unlimited distance Needs less network bandwidth EMC SAN Copy
Fast Central Data Center Uses the SAN or WAN to make copies Full or incremental copies Bi-directional Data Data No server cycles used Data Simple London Data Uses Navisphere or CLI to manage Data No additional hardware Data Open Data

CLARiiON Replication Products and ESX Server Interoperability CLARiiON Replication Products are only supported with raw device mappings (RDMs) Virtual machine OS images as well as the application data can be replicated Replica can be presented to the same ESX Server but must be presented to a different virtual machine Allows one virtual machine to use the production LUN and another virtual machine on the same ESX Server to access the replica
