We worked with Dell EMC storage Healthcare for around five years.

We also used Buffalo TeraStation for additional backup. I am referring to PowerVault storage array. 

We used a solution from HP before this one.

We previously used a different solution from IBM.  

I'm familiar with HPE 3PAR and HPE Nimble Storage. I used to work with both of them in my previous company approximately six years ago.

We are now Dell and Lenovo partners, and I have switched to their technology.

We work with Dell Unity and Unity HC for PowerStore. We also work with the new series of Lenovo, DE, and DM.
