FREQUENTLY ASKED QUESTIONS ABOUT P49749-001
What is the difference between P49749-001 and P49053-B21?
They are the same physical drive under different HPE numbering schemes. P49749-001, this page, is the spare part number, the one HPE service documentation and iLO logs cite for replacement. P49053-B21 is the option kit number used when the drive is ordered as a configurable add-on. This family also includes one assembly revision and four OEM drive models, all listed in the cross-reference block on this page. An assembly number identifies the drive as built with its carrier; an OEM model number is the manufacturer's own designation printed on the drive label.
Does this drive arrive ready to install, or do I need a caddy?
It is bundled with an HPE Basic Carrier, so the drive arrives already mounted for a 2.5" SFF bay. You do not need to transfer the failed drive's carrier. The device is hot-swap, so on a supported ProLiant server the replacement can be inserted into the bay without powering the system down, following your controller's normal drive replacement procedure.
What are the interface and speed specifications?
The drive uses a single SAS interface at 24Gb/s. The published drive transfer rate is 22.5 Gb/s external. Capacity is 3.2 TB and the form factor is 2.5" SFF. It is classified as a Mixed Use drive, the endurance class HPE assigns to workloads combining read and write activity, so it should be matched against the same class when replacing a failed unit in an existing array.
Which servers accept this drive?
Listed compatibility covers ML30 Gen10 Plus, DL20 Gen10 Plus, DL325 Gen10 Plus v2, DL345 Gen10 Plus, DL360 Gen10 Plus, DL365 Gen10 Plus, DL380 Gen10 Plus, and DL385 Gen10 Plus v2; ML30, ML110, ML350, DL20, DL320, DL325, DL345, DL360, DL365, DL380, DL385, and DL560 Gen11; and ML350, DL320, DL340, DL345, DL360, DL380, and DL580 Gen12. The server must provide a 2.5" SFF bay.
Why does the label on my failed drive show a different number?
HPE drives carry several numbers at once. The spare number, P49749-001 on this page, is the service identifier. The physical media may also be marked with an OEM model number, which is the drive manufacturer's own designation, and there is an assembly number covering the drive with its carrier. All of these map to the same 3.2TB SAS 24G Mixed Use SFF drive and are shown in the cross-reference block on this page.
