HP D2600 disk enclosures are one option of two models within the D2000 disk enclosure series. The main difference between these two options is their form factor and the number of drive bays they support. The HP D2600 is the Large Form Factor (LFF) option, and offers 12 3.5 inch drive bays that support either 12 Serial Attached SCSI (SAS) or 12 Serial Advanced Technology Attachment (SATA) disk drives. This allows HP D2600 disk enclosures to offer a maximum storage capacity of either 60 Terabytes (TB) when using SAS drives or 192TB when using SATA drives. Either way, the HP D2600 offers other performance capabilities not contingent on the drive type which include a host interface of 6 Gigabits per second (Gb/s), as well as support for a wide range of operating systems (OS) including Microsoft, Red Hat, VMware, HP-UX and more.
