Baies de stockage Dell PowerVault MD – neuves et reconditionnées

FAQ

What role do Dell PowerVault MD storage arrays play in an IT infrastructure?

Dell PowerVault MD arrays let you store data outside the server. They add extra capacity, and models with RAID controllers also protect your data if a drive fails. They are most often used by small and medium-sized businesses for virtualization, backups, file servers and databases.

What is the difference between Dell PowerVault MD1xxx and MD3xxx arrays?

MD1 series models (e.g. MD1200, MD1400) are usually drive enclosures that connect directly to a server and have no RAID controllers of their own. MD3 series models (e.g. MD3200, MD3800i) are full storage arrays with controllers that manage volumes and RAID themselves. Check the specification of the specific model for exact details.

What connection interfaces do PowerVault MD arrays offer?

Depending on the model, PowerVault MD arrays connect to servers via SAS, iSCSI or Fibre Channel. SAS works well for direct connections to a few servers, while iSCSI and FC are better suited to sharing resources over a network. Before buying, make sure your server has the right adapters or controllers.

How do I choose a Dell PowerVault MD array for my needs?

Start with the capacity you need, the number of drives and their form factor (2.5" or 3.5"). Then check which interface (SAS, iSCSI, FC) your servers support. If uptime is important to you, also check whether the array has redundant controllers and power supplies.

Can I increase the capacity of a PowerVault MD by adding more drives?

Yes, but the options depend on the specific model. Some MD3 series arrays support attaching additional drive enclosures, and drives are usually installed in dedicated caddies. Before buying, check the list of compatible drives, enclosures and firmware versions to avoid problems with the setup.
