Make sure they are at least the same size or larger than the source volumes. This is also where your disk truly shines, because disk head movement is minimal, so you can get high disk transfer speeds.
All PS Series storage arrays include SAN configuration features and capabilities that sense network topology, automatically build RAID sets, and conduct system health checks to help ensure that all components are fully functional.
Use the LeftHand management console to un-map the target volume or volumes from the target server, and remap them to the proxy server. When running the below explained benchmarks, your disk should be as idle as possible.
In the Application Servers snap-in, map the snapshot volumes to the target server. Cleanly restart the array, if currently running firmware prior to V2.
Disk enclosures Dell Compellent disk enclosures feature the latest industry-standard technology, including 6Gb SAS interconnects, so organizations can scale up and out with ease. Subsequently, only incremental changes in data are captured and the system uses real-time intelligence to create virtual pointers between all associated blocks.
This can involve shutting down the hosts accessing the group before beginning the update procedure. Unfortunately, many real world workloads involve access patterns that are much closer to random access than sequential access.
If you have run the grpparams disallow-downgrade command in the group see grpparams disallow-downgradesyou cannot return any group member to a PS Series firmware version prior to V3.
When the array shuts down, the network connection closes. Regular backups should be a vital part of maintaining a storage environment. Also, migrating data to new drives can be performed without disruption. You can gain instant visibility and control of a multi-terabyte, multilocation environment, streamlining administration and reducing operating costs.
Our downtime for the entire migration project has been limited to minutes per server, regardless of the size and number of volumes.
Space-efficient snapshots Dell Compellent Data Instant Replay enables organizations to take thousands of continuous snapshots to speed recovery to any point in time.
In some cases, you may need to make modifications to the operating system. All migration occurs transparently while applications remain online. Those volumes indicating a "Complete Image" status of "Established" have been completely migrated.
Redundant controllers will prevent volume connections between hosts and SAN from being dropped in the event of an active controller failure. You may now use the LeftHand management console to un-map the volumes from the SANmelody proxy server.
These certified and validated platforms ensure seamless interoperability and support.Step-by-step procedure for migrating NTFS volumes from a LeftHand SAN to another storage array. Updating Storage Array Firmware You should always run the latest PS Series storage array firmware, located on the EqualLogic Customer Support website, to take advantage of new product features, enhancements, and bug fixes.

Ask for different specification to suit your requirements. Reset and Setup Dell EqualLogic Array I recently had to reset and set up a Dell EqualLogic PS SAN array.
At the same time, I decided to upgrade the firmware on the array, before placing it back into production.Download
