Why enterprise-class MD3800i iSCSI array controller fail over required?

The PowerVault MD3800i offers flexibility through single or dual active/active controllers with either a 4GB or 8GB cache per controller in dual-controller configurations. Dynamic Disk Pools (DDP) can support up to 1024TB of data in up to 20 disk pools with up to 120 SSD drives with an optional configuration to RAID disk management.

When all of your mission critical application workloads and information assets are consolidated onto a storage platform, the need for high-performance, non-disruptive scalability, and continuous availability from that storage increases.

A data-center-class, high availability SAN needs to be completely resilient through data protection provided by RAID or mirroring, redundancy of power supplies and cache batteries, and, most important, dual controllers.

A dual-controller design not only achieves high availability by providing redundant paths
between the servers and the data they need to access, it doubles the storage processing power of the array.



The MD3800i iSCSI array has a 2U form factor that holds up to twelve 3.5” or 2.5” SAS, near-line SAS, and SSD drives for a high scalability.


One best practice is, to begin with one controller active and the other standing by in case of failure. As the demands of your virtualized applications grow, you can make both controllers active to share the load and still enjoy the resiliency of failover. When using an active/passive iSCSI target, use a preferred path failover policy. This makes servers use the preferred path whenever it is available, failover when it’s not, and fail back to the preferred controller when it comes online again. When using an active/active iSCSI target, you should use MRU (most recently used) failover.
