EMC’s CLARiiON Software EnvironmentCLARiiON operating environment (FLARE)

CLARiiON metaLUNsCLARiiON virtual LUN technology (dynamic LUN migration)

CLARiiON Replication Products SnapView: Local point-in time replicas on disksMirrorView: Replicas to other CX systemsSAN Copy: Multi-vendor data mobility and protection

CLARiiON management softwareNavisphere

CLARiiON MetaLUN ProvisioningCreates an abstraction of the physical placement of dataMetaLUNs enable quick response for additional storage

Application stays online with no disruption (host-platform-dependent)

Benefits of metaLUNs: Better capacity utilization from anywhere within arrayLets you spread data over more spindles for better performance

Includes striping capabilities for enhanced LUN expansion

CLARiiON Virtual LUN TechnologyMoves volumes within a CLARiiON CX system without application disruptionMakes management easier

Tiered storage within a CLARiiON CX series systemOptimize performance—up or downUse all available capacityMove 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

Storage-based product; uses no host cyclesProvides up to 8 replicas per source – each

Full image copies of production information, called business continuance volumes (BCVs or clones)Logical point-in-time views of production information, called snapshots

SnapView Replica restores Source Return to original production data at time of splitCan be mounted to secondary host to verify data consistency

MirrorView: Remote ReplicationMirroring between CLARiiON systems

Storage-based; uses no host cyclesBi-directional mirroring for maximum protection

Enables complete failover of production environment to remote site

Protects critical production information from planned and unplanned downtimeProtection from natural, mechanical, and environmental disasters Minimizes planned downtime for equipment upgrades, disaster recovery process testing

CLARiiON Replication Products andESX 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 replicatedReplica 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
