The order in which SSMs are added to the cluster determines the
order in which copies of data are written to the volume.

Configurable Snapshot Package
Snapshot -- a set of incremental pointers of a
volume at a point in time. It allows the users to
“roll back” the volume to its state at a certain point
in time in the past.
Features:
• Can be automated on a per volume basis with
retention policies, etc.
• No limit on the number of Snapshots
• Can be mounted as Read-Only volumes for
backup or single file restore purposes.

Snapshot 1(preserves original

Rollback Volume:
Volume reverts back to the point in time the
snapshot was created
Benefits:
• Near instantaneous retrieval of data
compared to tape backup solutions.
• Facilitates recovery to pre-error state
(compared to mirroring, which would mirror all
errors)
• Minimal storage space required by
incremental pointers to only delta (change)
blocks.
• Some competitors require large “set aside”
storage to be pre-allocated for snapshots.
LeftHand allows Snapshots to start small and
“Autogrow” as needed.

Snapshot – Layered Architecture
 Volume/snapshot relationship can
be conceptually thought of as
“layers”
 Space is allocated from the storage
pool to accommodate snapshots
User_Data
 User_Data_ss1 is the base line
snapshot, the volume is read only
 User_Data_ss2 contains the deltas
since User_Data_ss1 was created
User_Data_ss2
 User_Data contains the deltas since
User_Data_ss2 was created.
 The User_Data volume is comprised
of User_Data + User_Data_ss2 +
User_Data_ss1

Remote Data Protection Package – “Killer App”
Remote Data Protection provides
cost-efficient site diversity
Site A

No distance limitations with IP protocol

Affordable due to Ethernet underpinnings

Can be managed from one location

Easy off-site backup management, either real-time or via snapshot

Remote Data Protection replicates at the block level
– Efficient for whole volume replication

Remote Data Protection replicates incrementally
– After the baseline level snapshot, future snapshot layers to be copied only contain
incremental data.

Remote Data Protection is efficient in dealing with network glitches
– Copy is done in10% increments. If the network failed in the middle of a large volume
copy, the resumed copy will start at the closest 10% mark.

Remote Data Protection can be used to create “in Place” copies of volumes
– Can be used to facilitate development, testing, or Data Mining efforts

Remote Data Protection supports multiple sites replicated to a central site
– Can be used to facilitate centralized backup

Remote Data Protection can replicate bi-directionally between 2 sites. Allows for a
company with multiple locations to provide Disaster Recovery for each site

SANs: Primary Uses & Advantages
SAN Advantages
• Centralize data management for all applications, database, email etc.
• Separate application and data management – no application disruption for data
manipulation
• Increase storage utilization
• Increase utilization by creating a shared storage “pool” – no stranded capacity
• Improve performance
• Aggregate network links, cache, processors and HDD spindles for high
powered storage network
• Server consolidation
• Consolidate servers by creating separate, independently managed storage
pool – allow servers to function in their primary task of application serving –
not managing storage.
• High availability
• Create redundant storage networks with IP or FC SAN fabric for full enterprise
wide redundancy and high availability
*Third-party marks and brands are the property of their respective owners.
Copyright © Intel Corporation 2004
SANs: Primary Uses & Advantages
SAN Advantages (continued)
• Real-Time backup
• By separating storage and applications, administrators can perform backup
operations by implementing technologies such as Snapshot without
interrupting user access or application performance
• Disaster recovery / Business continuance
• SAN technology using Remote Copy allows administrators to manage remote
SAN installations and migrate data from one environment to another
seamlessly in the background. Ideal for centralized corporate backups,
archiving and disaster recovery / business continuance scenarios
