Enterprise IT hardware, supplied by the lot.

Across those categories we document 88 product families in circulation, with the part number prefix or physical marker that identifies each one, as identification help rather than a stock list, starting with the hard drive families that circulate on the secondary market and how to tell them apart.

Holding stock rather than buying it? GTR Supply also buys surplus IT hardware by the lot, and every category has a page of its own setting out what to put on your list.

Buying by the lot for the first time? The guides to buying enterprise IT hardware by the lot cover what a condition grade actually covers, what a manifest has to carry, and what to check on a used drive before price is worth discussing.

Not certain what you are looking at? The brands we buy and sell, and how to identify each one show where the service tag, product number or part number physically sits on Dell, HPE, Supermicro, Seagate, Western Digital, Nvidia and Cisco hardware, and how to read it. Those pages are identification help rather than stock lists.
