HPE ProLiant BL620c G7 Hard Drives
Genuine HPE hot-plug hard drives and solid state drives for the HPE ProLiant BL620c G7, new and refurbished, tested before shipping. A blade this large still carries only two small form factor bays, in positions 1 and 2 on the embedded Smart Array P410i — and HPE does not support mixing SAS, SATA and SSD drives inside one blade.
BL620c G7 Drive Specifications
- Bays: two hot-plug 2.5-inch SAS, SATA or SSD bays, positions 1 and 2, both served by the embedded Smart Array P410i
- Interface: 6G SAS and 3G SATA, through two internal x4 wide-port SAS connectors on the controller
- Maximum internal storage: 2.4TB on SAS, 2.0TB on SATA, 1.6TB on solid state drives
- Documented families: 6G SAS enterprise drives at 10K and 15K rpm, 6G SAS midline at 7.2K, 3G SATA midline at 7.2K, and SATA value and mainstream endurance solid state drives
- Mixing: not supported — SAS, SATA and SSD drives cannot be combined within the same blade
- RAID: the P410i supports RAID 0 and RAID 1 here, and both need two drives installed
Two bays, one drive type. HPE does not support mixing SAS, SATA and SSD drives within the same blade, so the drive already fitted decides what the second one has to be. Both bays filled gives 2.4TB on SAS, 2.0TB on SATA or 1.6TB on solid state — halve that if the pair is mirrored.
What fits in two BL620c G7 bays?
| Drive family | Largest documented drive | Both bays filled |
|---|---|---|
| 6G SAS enterprise, 10K and 15K | 1.2TB | 2.4TB |
| 6G SAS midline, 7.2K | 1.0TB | 2.0TB |
| 3G SATA midline, 7.2K | 1.0TB | 2.0TB |
| 6G SATA solid state | 800GB | 1.6TB |
With two bays the array is a mirrored pair or a stripe, and that decides the shape of the whole build: a mirror halves the usable capacity in the table above, a stripe keeps it and gives up the redundancy. Anything larger belongs outside the blade, on a Smart Array mezzanine controller or a Fibre Channel mezzanine card, which is why so many of these blades run a small mirrored pair for the operating system and nothing else.
Choosing the Right BL620c G7 Hard Drive
- Match the type already fitted. SAS, SATA and SSD cannot be mixed in one blade, so a second drive has to follow the first rather than the price list.
- Order two if you want RAID. Both RAID 0 and RAID 1 require two drives installed, and a single drive leaves the P410i with nothing to protect.
- The bays are 2.5-inch hot-plug only. Drives arrive in HPE hot-plug carriers sized for the bay; there is no large form factor option on this chassis at any point in its life.
- Match the whole storage path. HPE notes that drive, controller, firmware and backplane should run at the same transfer rate, or the system negotiates down to the slowest part of the path — and this path is 6G SAS and 3G SATA.
- Enterprise for transactions, midline for bulk. The 10K and 15K enterprise SAS drives carry the duty cycle; the 7.2K midline drives carry the capacity per pound across the same two bays.

BL620c G7 Hard Drives FAQ
How many drives does a BL620c G7 hold?
Two hot-plug small form factor drives, in bays 1 and 2, both attached to the embedded Smart Array P410i. There is no drive cage option and no large form factor version of this blade.
Can I mix SAS and SATA drives in a BL620c G7?
No. HPE states that SAS, SATA and SSD drives cannot be mixed within the server, so both bays carry the same type of drive.
What is the maximum internal storage of a BL620c G7?
2.4TB on two 1.2TB SAS drives, 2.0TB on two 1TB SATA drives, or 1.6TB on two 800GB solid state drives.
Do I need two drives for RAID on this blade?
Yes. The P410i supports RAID 0 and RAID 1 here, and both levels require two drives installed in the blade.
Will a 12G SAS drive run any faster in a BL620c G7?
No. The storage path on this blade is 6G SAS and 3G SATA, and HPE notes that drive, controller, firmware and backplane all negotiate down to the slowest component in the chain.
Where does bulk storage go on a blade with two bays?
Outside the blade. Two bays cover boot and a working set; larger arrays attach through a Smart Array mezzanine controller to SAS storage outside the enclosure, or through a Fibre Channel mezzanine card to a SAN.
