The HPE P53552-B21 is a 20TB SAS hard drive in a Smart Carrier tray for HPE ProLiant servers. It is a full-size 3.5-inch drive, not a 2.5-inch one. It spins at 7200 RPM and links at 12Gb/s.
HPE calls it "20TB SAS 12G Business Critical 7.2K LFF SC Helium 512e ISE Multi Vendor HDD". Here is what the odd bits mean.
| In the name | What it means |
|---|---|
| Business Critical | HPE's drive class name |
| LFF | Large form factor, 3.5-inch |
| SC | Smart Carrier tray |
| Helium | Helium-filled case |
| 512e | 512-byte sectors on a 4K drive |
| ISE | Instant Secure Erase |
| Multi Vendor | HPE may supply it from more than one drive maker |
HPE sells this 20TB drive with two carrier types. P53552-B21, spare P54676-001, uses the Smart Carrier. P53553-B21, spare P54677-001, uses the Low Profile carrier made for certain Gen10 Plus and Gen11 servers.
The SC version suits ProLiant bays that take Smart Carriers, mostly Gen8 through Gen10 models. Check your server's carrier type first, because the two carriers differ.
LFF, which is 3.5-inch. SFF means 2.5-inch. Some listings mix the two up, so read the part number.
Instant Secure Erase wipes the drive in seconds before you retire it.
Helium is thinner than air, so the platters spin with less drag. That trims power and heat.
Twelve drives hold 240TB raw. RAID 6 leaves about 200TB usable.
HPE's parts data lists the assembly number P54555-001. The label may show model MB020000JXMTP, MB020000JXMVU, or MB020000JXQHK. All three map to this one option part number. That is how a multi-vendor drive works.
Parts sellers list the P53552-B21 for Gen10 models such as the DL360, DL380, DL385, and ML350, and for many Gen8 and Gen9 servers. Check your own model against HPE's list.
