Supported Cluster Configurations - Dell PowerVault MD3600f Hardware Installation And Troubleshooting Manual

Advanced Features
Advanced features for the PowerVault MD3600f and MD3620f RAID storage
systems include:
Snapshot Virtual Disk—Captures point-in-time images of a virtual disk
•
for backup, testing, or data processing without affecting the contents of
the source virtual disk.
• Virtual Disk Copy—Generates a full copy of data from the source virtual
disk to the target virtual disk in a storage array. You can use Virtual Disk
Copy to back up data, copy data from disk groups that use smaller-capacity
physical disks to disk groups using greater capacity physical disks, or restore
snapshot virtual disk data to the source virtual disk.
• Upgrading to High-Performance Tier—Increases the performance of the
system beyond that of a MD36x0f series array operating at the standard
performance level.
Remote Replication—Enables real-time replication of data between two
•
storage arrays in separate locations.

Storage Manager Features" on page 63.

Supported Cluster Configurations

The following sections describe the supported cluster configurations.
Direct-Attached Cluster
In a direct-attached cluster, all the nodes of the cluster are directly attached
to a single storage system. In this configuration, the RAID controllers on the
storage system are connected by cables directly to the Fibre Channel HBA
ports in the nodes.
Figure 1-1 shows a basic direct-attached, single-cluster configuration.
