Dell PowerStore 1200T
The Dell PowerStore 1200T represents the second-generation refresh of Dell's mainstream mid-range all-flash array, powered by updated Intel Ice Lake Xeon processors. Delivering up to 20% higher IOPS and greater bandwidth than the preceding 1000T, the 1200T features end-to-end NVMe expansion enclosures (NVMe DAE) running over 100GbE QSFP connections instead of legacy SAS cables. The system delivers unified block, file, and vVols storage with persistent 4:1 hardware data reduction. Refurbished system purchasers should ensure NVMe expansion cabling (100GbE direct-attach copper) is supplied when buying multi-enclosure systems.

Works together
How the Dell PowerStore 1200T connects to servers, storage and the network: 3 ways, with the parts and products on each path.
Fibre Channel SAN
Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).
