Scalability Package
SSM Clusters
Scalability Package allows multiple SANform M200 units to pool storage and connectivity resources. A cluster is a
grouping of SSMs from which you create volumes and assign data replication levels. Clusters bring better performance
and reliability to the IP SAN.
How Replication Works
4 Blocks of Data
4 Blocks of Data
4 Blocks of Data
Replication = 1
Replication = 2
Replication = 3
The order in which SSM's are added to the cluster determines the order in
which copies of data are written to the volume.
Cross Unit Striping Scenario
Example:
5 SSM Cluster Fully Meshed
Volume 1 is striped across 5 individual SSM's
Replication level = 2 (can be up to 3)
Benefits:
Load Balancing
5 GigE connection points to Volume 1
Highly redundant, fault tolerant system
Enable spread of data over a dynamic number of spindles
Configurable Snapshot Package
Snapshots
Snapshots provide a fixed version of a volume for read-only access. The configurable Snapshot Package upgrade for the
SANform M200 allows snapshots to be created automatically, and the physical size of a snapshot to be changed.
How a Snapshot Works
User_Data Volume composed of Disk Blocks A, B and C.
User_Data Volume composed of modified Disk Blocks.
New volume is created to hold any changed blocks
Previous volume becomes Snapshot volume, and is read only
All operations are transparent to the operating system and the user community. Snapshots happen instantaneously.
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_ss1 is the baseline snapshot; the volume is read only
User_Data_ss2 contains the deltas since User_Data_ss1 was created
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
Remote Data Protection Package
The Remote Data Protection Package upgrade for the SANform M200 allows for volumes to be copied to a remote
SANform M200 unit over an IP network.
Remote Data Protection Example
Storage control console helps enable centralized data management
Cross-replication between sites supports operational failover
Ad hoc or scheduled replication
Incremental updates help to minimize bandwidth and telecom costs
Interrupted updates restart, rewrite previous 10%
