Confirming fit

Memory Clearance does not publish a verified compatibility list for 25L1800. Whether a part of this type is supported is defined by the system or switch vendor's own compatibility matrix, not by the part on its own.

The dependable check is the part number. Read the installed part number from the system's management interface and compare it with the number on this listing. If you send your server model with a quote request, it is checked against this part before you order.

Common questions

Is 25L1800 in stock?

Stock moves, so the quantity shown on this listing is the current figure. For a larger quantity, send the part number and how many you need and the answer comes back against that exact number. Quotes are answered weekdays 8:00 am to 5:00 pm PST.

Does this drive come with a tray?

Only if the listing name says so. Drive listings are either bare or supplied in a generation-matched hot-swap tray, and the name states which.

Can I use this to replace a failed array member?

Match the interface, the capacity, the sector format and the class of the drive already in the array. A mismatch on any of those can be rejected by the controller.

What do I send to get a price on 25L1800?

The part number, the quantity, the condition you will accept and the server model it goes into. That is enough to answer in one pass.
