FREQUENTLY ASKED QUESTIONS ABOUT P49049-B21
What is the difference between P49049-B21 and P49747-001?
They are the same physical drive under different HPE numbering schemes. P49049-B21, this page, is the option part number — the orderable configuration number used when specifying or expanding a server. P49747-001 is the spare part number used for service replacement. 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 a specific build revision of the drive and carrier; an OEM model number is the manufacturer's own drive designation.
Which servers accept this drive?
Supported platforms are 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-inch SFF bay.
What does the Basic Carrier bundling mean for installation?
The drive ships already installed in an HPE Basic Carrier, so no separate tray or caddy purchase is needed for a 2.5-inch SFF bay. Because the device is hot-swap, it can be inserted or removed while the server is running, subject to the controller and array configuration in use. Confirm your chassis uses SFF bays rather than LFF before ordering.
What does the Mixed Use drive class indicate?
Mixed Use is HPE's endurance classification for drives intended to handle both read and write activity, sitting between Read Intensive and Write Intensive options. It suits workloads such as virtualization, databases and general-purpose application storage where writes form a meaningful portion of daily I/O rather than an occasional operation. Choose the class that matches your measured daily write volume rather than capacity alone.
What interface and speed does this drive use?
The drive presents one SAS interface operating at 24 Gb/s. It will attach to a SAS controller or backplane in a supported 2.5-inch SFF bay. As with any SAS deployment, the negotiated link rate depends on the controller, expander and backplane in the path, so verify the storage subsystem in your specific server configuration supports SAS 24Gb/s to realize full interface speed.
