Dell Unity XT Storage Arrays – new and refurbished

FAQ

What is the difference between a new Dell Unity XT array and a refurbished one?

A new array has never been used. A refurbished (ex-lease) array has already run in another environment, but it usually costs less. For either option, check the listing for the configuration, the condition of the hardware, the scope of the licenses and the warranty terms. These determine the real value of your purchase.

Will a controller or power supply failure stop a Unity XT array?

Unity XT has redundant controllers, power supplies and fans, so the failure of one of these components should not interrupt the system's operation. However, continuous operation also depends on correct configuration, proper connections to the servers and up-to-date software. When planning your environment, also factor in backups and replication.

All-flash or hybrid Unity XT: which configuration should you choose?

All-flash makes sense where low latency and high performance matter, such as for databases or virtualized production applications. A hybrid configuration combines SSDs and HDDs, which provides more capacity at a lower cost, for example for files or archives. The right choice depends on your workload type and budget.

How do you expand a Dell Unity XT array with additional drives?

You increase capacity by adding drives or expansion enclosures. What is possible depends on the specific model and its current configuration, so before buying, check the compatibility of drive and enclosure types, as well as the limits of the given model. If you have any doubts, consult an advisor about your selection.

How do you choose the right Unity XT configuration for your company?

Start with the amount of data and expected growth, the type of workload (virtual machines, databases, files) and the protocols you need: FC, iSCSI or NFS/CIFS. Also consider your requirements for performance, backup and replication. Based on this, you can select the model, the type and number of drives, and any expansion enclosures.
