Dell PowerVault MD3620i Storage Arrays – new and refurbished

FAQ

What is the Dell PowerVault MD3620i disk array used for in a company's IT infrastructure?

It is a server storage array that lets several servers share the same disk resources at the same time. It connects to them over an iSCSI network, so you don't need a separate Fibre Channel infrastructure. It works well in virtualization environments, for databases, file servers and backups in small and medium-sized businesses.

How does the MD3620i differ from the MD3600i?

Both arrays belong to the MD36xx series and use the iSCSI standard. The main difference is the enclosure: the MD3620i supports 2.5" drives (24 bays), while the MD3600i supports 3.5" drives (12 bays). The right choice depends on what matters more to you: the number of drives and performance, or greater capacity per drive.

What types of drives does the MD3620i support?

The unit supports 2.5" SAS, NL-SAS and SSD drives. Before you buy drives, make sure they are compatible with the array and its firmware version. You will also need the right drive carriers (caddies), so check what is included in the specific listing.

How do I connect the MD3620i to servers?

The connection runs over an Ethernet network using the iSCSI standard, either directly or through switches. The servers need network adapters that support iSCSI. For larger deployments, it is worth setting up a separate network for storage traffic, as this helps with stability and performance. The details depend on the number of hosts and the redundancy you require.

Can I increase the capacity of the MD3620i by adding more drives?

Yes, MD36xx series arrays can be expanded with compatible disk enclosures, for example from the PowerVault MD12xx family. This lets you increase capacity without replacing the entire system. The maximum number of drives depends on the configuration and licensing, so check the manufacturer's specifications before expanding.
