Description
HP P40498-B21 960GB 2.5" Read Intensive SSD
The P40498-B21 is a 960GB Read Intensive drive from HP, built in the 2.5-inch SFF size on triple-level cell flash and coded to the ProLiant product line. It's hot-pluggable, so it goes in and out of a running chassis without a shutdown. A drive at this capacity and rating has one role that gets overlooked at purchase time, which is sitting in a bay doing nothing at all until the day something breaks.
Key Features
- 960GB of capacity in a single 2.5-inch SFF body
- Read Intensive endurance rating, aimed at data served far more than it's written
- Triple-level cell flash, three bits held in every memory cell
- Hot-pluggable, so it swaps out with the chassis still powered
- HP ProLiant product line coding
- HP part number P40498-B21, the code to quote on a spares list
Performance and Applications
A hot spare is the cheapest insurance an array can carry. It sits idle in a bay, and the moment a member fails, the controller adopts it into the group and begins rebuilding, with nobody needing to touch the rack. The alternative is a degraded array waiting for someone to spot the alert, raise a purchase order, and drive to site. Buy one drive beyond what the array needs and that entire sequence stops existing. The spare has to match the group it protects, which is why it belongs on the same order as the rest.
Compatibility and Installation
Your spare needs to match the drives it might stand in for, in capacity, interface, and generation, or the controller will refuse to adopt it. You'll want a free SFF bay and the carrier tray your chassis generation takes. Assign it as a hot spare in the controller afterwards rather than leaving it sitting as an unconfigured disk.
HP P40498-B21 960GB SSD for Array Hot Spare Duty
For an array running with an empty bay and no backup plan, this closes the gap before it opens. 960GB of Read Intensive flash sitting ready, waiting to do nothing until the day it has to.
