SnapDrive 5.2.2 for UNIX includes several new features and enhancements.
- Supports clustered Data ONTAP 8.3
- Supports the following clustered Data ONTAP features:
- Load-sharing mirror (LSM)
A load-sharing mirror reduces the network traffic to a FlexVol volume by providing additional read-only access to clients. You can create and manage load-sharing mirrors to distribute read-only traffic away from a FlexVol volume. Load-sharing mirrors do not support Infinite Volumes. A set of load-sharing mirrors consists of a source volume that can connect with one or more destination volumes. Each load-sharing mirror in the set must belong to the same Storage Virtual Machine (SVM) as the source volume of the set. The load-sharing mirrors should also be created on different aggregates and accessed by different nodes in the cluster to achieve proper load balancing of client requests.
For more information, see the Clustered Data ONTAP Logical Storage Management Guide.Note: If you are using clustered Data ONTAP 8.2, 8.2.1, or 8.2.2, the load-sharing mirror update fails if the cluster administrator is not configured. You must configure the cluster administrator using the snapdrive config set -cserver command.
- Selective LUN Map (SLM)
Beginning with clustered Data ONTAP 8.3, the Selective LUN Map (SLM) feature is enabled by default on all new LUN maps. When a new LUN map is created, the LUN is accessible only through paths on the node that owns the LUN and its HA partner.
You can refer Using Selective LUN Map in SnapDrive for UNIX for information on configuration parameters. For more information, see the
Clustered Data ONTAP SAN Administration Guide.
Note: This feature is supported only if you are using clustered Data ONTAP 8.3.
- IPspaces
An IPspace defines a distinct IP address space in which Storage Virtual Machines (SVMs) can be created. A routing table is maintained for each SVM within an IPspace; no cross-SVM or cross-IPspace traffic routing occurs.
For more information, see the Clustered Data ONTAP Network Management Guide.Note: This feature is supported only if you are using clustered Data ONTAP 8.3.
- MetroCluster setup
This feature is supported only if you are using clustered Data ONTAP 8.3. For information about MetroCluster setup, see the Clustered Data ONTAP MetroCluster Installation and Configuration Guide.
- Tokens to reserve space on node to create FlexClone files and FlexClone LUNs
You must have the FlexClone license if you want to use this feature. For more information, see the Clustered Data ONTAP Logical Storage Management Guide.
- Custom qtree exports
The qtree can have different exportfs policy than the parent volume.
Note: This feature is supported only if you are using clustered Data ONTAP 8.2.1 and later.
- Supports Federal Information Processing Standard (FIPS) compliance
Note: For updated information about SnapDrive for UNIX and its requirements, see the Interoperability Matrix.
