HPE ProLiant DL585 G7 Hard Drives
Genuine HPE hot-plug hard drives for the HPE ProLiant DL585 G7, new and refurbished, tested before shipping. This is a 4U server with only eight drive bays, all of them 2.5-inch small form factor — the chassis volume went to four processor sockets and 48 DIMM slots, not to spindles, so internal storage here is a boot and working set, not a capacity tier.
DL585 G7 Drive Specifications
- Bays: up to eight hot-plug small form factor (2.5-inch) SAS, SATA or solid state bays on an internal SAS backplane — HPE lists no large form factor cage for this server
- Extra slot: one additional internal SSD slot beyond the eight front bays
- Maximum spinning capacity: 9.6TB on eight 1.2TB SFF SAS drives, or 8.0TB on eight 1TB SFF SATA drives
- Solid state ceiling: 6.4TB, on eight 800GB SAS SSDs or eight 800GB SATA SSDs
- Interface: 6Gb/s SAS and 3Gb/s SATA, presented to the embedded Smart Array P410i over two internal 4X SAS connectors
- Past the eight bays: external D2600 and D2700 disk enclosures, up to eight D2600 or four D2700 from a Smart Array P411 or P812
Eight bays, all of them 2.5-inch, and that is the ceiling. The DL585 G7 spends its 4U on four processor sockets and 48 DIMM slots rather than on spindles, so internal storage tops out at 9.6TB on eight 1.2TB SAS drives. The documented route past that is external: a Smart Array P411 or P812 into a D2600 or D2700 enclosure.
How Far Do Eight Bays Get You?
| Drive class | Largest listed | Eight bays hold | Suits |
|---|---|---|---|
| SFF SAS, hot plug | 1.2TB | 9.6TB | Transactional work and anything the four sockets are consolidating |
| SFF SATA midline | 1TB | 8.0TB | Bulk capacity per pound where duty cycle is light |
| SFF SAS or SATA SSD | 800GB | 6.4TB | Latency-sensitive volumes, boot and cache roles |
Eight bays is a hard ceiling on this chassis, and it is lower than the 2U ProLiants of the same generation reach. That is the trade a scale-up server makes, and it shapes how the storage is normally laid out: the internal bays carry the operating system and the hot working set, and bulk capacity goes outside the box on a P411 or P812 into a D2600 or D2700 shelf.
Choosing the Right DL585 G7 Hard Drive
- Every bay is 2.5-inch. A 3.5-inch drive has nowhere to go in this chassis, and no carrier or adapter changes that.
- Match the whole storage path. HPE notes that the drive, the controller, the firmware and the backplane should all run at the same transfer rate, or the system negotiates down to the slowest component in the chain.
- SAS for transactional, SATA midline for bulk. Enterprise SAS carries the higher spindle speeds and duty cycle; midline SATA carries the capacity per pound and a shorter warranty.
- Count free bays before you count terabytes. With eight bays and a RAID set already built, the practical upgrade is often larger drives rather than more of them.

DL585 G7 Hard Drives FAQ
How many hard drives does a DL585 G7 hold?
Up to eight hot-plug 2.5-inch SFF drives on the internal SAS backplane. HPE also documents one extra internal SSD slot in addition to those eight bays.
Does the DL585 G7 take 3.5-inch drives?
No. The internal backplane on this server supports small form factor drives only, and HPE lists no large form factor cage option for it, so every drive fitted is 2.5-inch.
What is the maximum internal storage of a DL585 G7?
9.6TB, using eight 1.2TB SFF SAS drives. SATA tops out at 8.0TB on eight 1TB drives, and solid state at 6.4TB on eight 800GB drives.
How do I add more storage than eight bays?
Outside the chassis. HPE documents up to eight D2600 enclosures or four D2700 enclosures attached to a Smart Array P411 or P812, which is the supported route past the internal bay count.
Can I use SATA drives in a DL585 G7?
Yes. The bays take SAS or SATA hot-plug drives, with SAS running at 6Gb/s and SATA at 3Gb/s on the embedded Smart Array P410i. SATA midline drives generally carry a shorter warranty than enterprise SAS.
Will a faster drive speed up an older array?
Not on its own. HPE notes that the drive, controller, firmware and backplane negotiate to a common transfer rate, so a fast drive on a slower path runs at the slower speed.
