Brands we trade
Brands We Buy and Sell
GTR Supply buys and sells enterprise IT hardware from the manufacturers that make up most of this trade: Dell, HPE and Supermicro in servers, Intel and AMD in processors, Samsung, Micron, Solidigm, Kioxia, Seagate and Western Digital in storage, SK hynix in memory, Nvidia in accelerators and Cisco in networking. These pages exist for one reason, and it is not the badge on the front of the box. Most people holding a room full of equipment cannot say what generation it is, where the identifying number physically sits, or why a product number tells a buyer far more than a model name does. Each page below teaches exactly that for one manufacturer, because a photograph of the right label turns a guess into a quote. Every part number and model name across these pages is identification help for the reader, never a stock listing. Send a part number and a quantity and we will tell you where we stand.
The pages
10 pages, grouped by what they are.
Each one teaches you how to identify the hardware from one manufacturer, then says what GTR Supply buys and sells in it. Written to be useful whether or not you ever trade anything with us.
Servers
Where the identifying number lives differs completely between the three, which is why these are three pages rather than one.
Processors
Intel and AMD on one page, because everything except the identification code is the same problem on both.
Storage
Flash and spinning disk, where the part number carries the specification and the capacity on the sticker does not.
Memory
Three companies make almost all of the die, so a pallet of a dozen brands is usually three families of parts.
Accelerators
Form factor decides more than the model name here, and the workstation line has been renamed twice.
Networking
Product IDs, airflow direction and the one licensing question that a seller needs answered before a pallet ships.
None of this is a stock list
Every model name and part number on this page is identification help for the reader. None of it is a stock listing, and nothing here says that GTR Supply holds a particular item. Send the part number and the quantity you need and we will tell you where we stand.
Why these are identification pages, not catalogues
A brand page that says we buy Dell servers and then repeats the sell page is worth nothing to a reader and worth less than nothing to a site, because eleven near identical pages is the pattern that gets a site demoted rather than ranked.
So these pages do the thing nobody else writes down properly. They tell you where the number that identifies your hardware physically is, how to read each field in it, and what it means. That is genuinely different per manufacturer, which is why the pages are genuinely different from each other. Dell puts a service tag on the front that resolves to the original build. Supermicro has no service tag at all and the number that matters is silkscreened on the motherboard. HPE has a product number that says far more than the model name. Seagate encodes the sector format inside the part number. Cisco encodes the week of manufacture inside the serial.
All of it is useful whether or not you ever trade with us, which is the standard every page here is written to.
Nothing on these pages is a stock listing
Every part number, model name and family on these pages is there to help you identify what you are holding or what you need. None of it says GTR Supply has that item, and no page claims stock of any specific model, part number, capacity or quantity.
That is deliberate rather than coy. Availability in this trade changes weekly and in some categories daily, so a published list of what is on the shelf would be wrong for most of the people reading it, and a wrong list wastes more of your time than no list does.
The framing across the whole site is the same and it works in both directions. Send the part number and the quantity you need and we will tell you where we stand: what we hold, what we can realistically put together, and where we are not the right party for it. On the buying side, send what you are clearing and a valuation comes back against your list rather than against a rate card.
Straight answers, including the unhelpful ones, are quicker for everybody.
Both sides of the desk, on every page
Each brand page covers what GTR Supply sells in that brand and what it buys, and that is not a formatting convention. It is because they are usually the same person.
The organisation that buys forty PowerEdge nodes is the organisation that has forty to clear three years later. The reseller taking a pallet of nearline drives this quarter is clearing an array next quarter. Splitting that reader across two pages that never mention each other makes the site less useful, so every page here links to the matching product category and the matching sell page and says plainly what happens in each direction.
It also keeps the writing honest. A page that only sells tends to describe hardware as better than it is, and a page that only buys tends to describe it as worse. Writing both sides at once makes it much harder to do either.
If you are on the wrong side of a page, the links at the foot of it will take you to the right one.
Brands that are not on this list
Eleven pages is not eleven brands. Several manufacturers are covered inside a page rather than given one of their own, because a separate page would have repeated four fifths of an existing one and said almost nothing new.
SK hynix is covered on the memory page, where it belongs, as one of the three companies that actually makes the die. HGST and SanDisk are covered on the Western Digital page, because they are the same house under earlier names and separating them would tell a seller the opposite of what is true. Solidigm and Intel are covered together on the enterprise SSD page for the same reason. Mellanox sits on the Nvidia page as the networking side of that business. Lenovo and IBM heritage names appear inside the server pages where they turn up in a decommission.
And if what you are holding is not named anywhere here, send it anyway. The categories on this site cover far more than eleven manufacturers, and you will get a straight answer either way.
Common questions
About these pages.
Do you actually stock the models listed on these pages?
No page on this site claims stock of any specific model, part number, capacity or quantity, and that is a deliberate rule rather than an oversight. Every part number and model name across these brand pages is identification help for the reader.
The reason is that availability changes weekly, and in the fastest moving categories it changes within a day. A published list of what is on the shelf would be wrong for most of the people reading it by the time they read it, and a wrong list wastes more of your time than no list does.
What happens instead is simple and it is what the rest of this site already says. Send the part number and the quantity you need and GTR Supply will tell you where we stand: what we hold, what we can realistically put together and how quickly, and where we are honestly not the right party for the requirement. Pricing and availability normally come back the same business day.
Is GTR Supply an authorized reseller for any of these manufacturers?
No. GTR Supply is an independent trader with no affiliation to, authorization from, or endorsement by any manufacturer named on this site. All product and company names are the trademarks of their respective owners, and they are used here only to describe hardware that is bought and sold.
That also means no manufacturer warranty, support entitlement or firmware entitlement is provided or transferred by us. Where a piece of equipment carries a licence, a support contract or a software subscription, whether and how any of it moves with the hardware is set by the manufacturer, not by a trader, and these pages describe how that works rather than claiming to change it.
What GTR Supply does provide is what it can stand behind: hardware that is tested and graded, drives securely wiped with a certificate of destruction available on request, a full manifest with every lot, and terms agreed before anything moves.
What if the brand I have is not listed here?
Send it anyway. These eleven pages cover the manufacturers that make up most of this trade, not the full list of what GTR Supply buys and sells, and the product categories on this site cover considerably more ground than eleven names.
Several manufacturers are also covered inside a page rather than given one of their own, so it is worth checking before you assume yours is missing. SK hynix is on the memory page. HGST and SanDisk are on the Western Digital page, because they are the same house under earlier names. Solidigm and Intel are together on the enterprise SSD page. Mellanox is on the Nvidia page.
If yours genuinely is not here, the useful thing to send is what you are holding rather than the brand: what the equipment is, roughly how much of it there is, and a photograph if typing is not realistic. You will get a straight answer, including where the answer is that we are not the right buyer for it.
