Baies de stockage Dell PowerVault MD3220 – neuves et reconditionnées

FAQ

What can a business use the Dell PowerVault MD3220 storage array for?

The Dell PowerVault MD3220 is a storage array with external SAS connectivity that gives servers a shared, centralized pool of storage. It works well for virtualization, databases, file and mail servers, and backups in small and medium-sized businesses. It replaces the local disks in individual servers with a single resource that is easier to manage.

How many drive bays does the MD3220 have, and what types of drives can be installed?

The MD3220 is a 2U enclosure that holds 24 2.5-inch drives. These are typically SAS, nearline SAS or SSD drives, so you can choose them to suit your performance or capacity needs. The array can also be expanded with additional Dell drive enclosures. It is worth checking the manufacturer's documentation for the exact list of compatible drive models and the expansion limit.

How is the MD3220 connected to servers?

The MD3220 connects directly to servers through a SAS interface, using HBA controllers and the appropriate cables. This means it does not need a separate SAN, as Fibre Channel or iSCSI would. This approach is simpler and cheaper to deploy. However, the number of hosts that can be supported depends on the number of ports on the array's controllers.

Which model should I choose: the MD3220, MD3200 or MD3220i, and how do they differ?

The MD3220 and MD3200 have the same SAS host interface but differ in enclosure type. The MD3220 holds 24 2.5-inch drives, while the MD3200 holds 12 3.5-inch drives. The MD3220i is the iSCSI version, which connects over an Ethernet network rather than directly with SAS cables. The right choice depends on how you want to connect your servers and how many drives you need.

What should I look for when choosing an MD3220 array?

Start by checking the controller configuration (one or two controllers, which affects fault tolerance), the number and type of drives, and the power supplies. Also make sure your servers have compatible SAS HBA cards. For used or off-lease equipment, the condition, warranty coverage and availability of replacement drives are important.
