HPE ProLiant SL4545 G7 Hard Drives
Genuine HPE hot-plug hard drives and solid state drives for the HPE ProLiant SL4545 G7, new and refurbished, tested before shipping. This chassis is storage first: up to 60 large form factor bays sit behind a Smart Array P420i in the rear I/O module, while each server node carries only two small form factor bays of its own — and those two are SATA.
SL4545 G7 Drive Specifications
- Chassis bays: 60 hot-plug LFF (3.5-inch) bays in the 1x60 model, 50 in the 2x25 and 45 in the 3x15, split evenly between the nodes
- Node bays: two hot-plug SFF (2.5-inch) bays on the front of every node, which HPE describes for the operating system, boot or additional storage
- Mixing in the main section: the LFF bays take any combination of SAS, SATA or SATA solid state drives
- Node bay interface: the two SFF bays run off the Dynamic Smart Array B110i SATA RAID on the node, and HPE's capacity tables list them with SATA drives only
- Maximum internal capacity: 240.0TB on sixty 4TB LFF drives, 200.0TB on fifty and 180.0TB on forty-five, in SAS or SATA
- Solid state ceiling: 48.0TB on sixty 800GB LFF SATA SSDs in the 1x60 model, and 1.6TB on two 800GB SFF SATA SSDs per node
The two bays on the node are not the same as the sixty in the chassis. The main storage section takes any mix of SAS, SATA and SATA solid state behind the Smart Array P420i, reaching 240.0TB on sixty 4TB drives. The two SFF bays on each node run off the B110i SATA RAID controller, and HPE documents those with SATA drives only.
How Many Drives Fit Your SL4545 G7 Chassis?
| Chassis model | Server nodes | LFF bays | SFF bays | Maximum LFF capacity |
|---|---|---|---|---|
| 1x60 | 1 | 60 | 2 | 240.0TB on 4TB drives |
| 2x25 | 2 | 50, up to 25 per node | 4, two per node | 200.0TB on 4TB drives |
| 3x15 | 3 | 45, up to 15 per node | 6, two per node | 180.0TB on 4TB drives |
Bays trade against nodes, and the chassis in front of you has already made the trade. The 1x60 puts every bay behind a single server; the 3x15 splits fewer bays across three. What matters when you order is the per-node figure rather than the chassis total, because an array cannot span nodes — 15 bays is the ceiling for one server in a 3x15.
Choosing the Right SL4545 G7 Hard Drive
- The two bays on the node are SATA. They hang off the B110i SATA RAID controller, and HPE documents them only with SATA drives and SSDs.
- Match the whole storage path. HPE notes the drive, the controller, firmware and backplane should all run at the same transfer rate, or bandwidth negotiates down to the slowest.
- SAS for spindle speed, midline for bulk. The 15K enterprise LFF drives here are 450GB and 600GB; capacity comes from the 7.2K midline families, to 4TB in SAS and SATA.
- Solid state on this platform is SATA. The LFF Value Endurance range covers 240GB to 800GB and the SFF Mainstream Endurance range 100GB to 800GB; neither is a SAS SSD.
- Drives seat in HPE SmartDrive carriers. The carrier is part of the drive assembly and matched to the bay, so an SFF drive will not go into an LFF bay.

SL4545 G7 Hard Drives FAQ
How many hard drives does an SL4545 G7 hold?
60 large form factor bays in the 1x60 model, 50 in the 2x25 (25 per node) and 45 in the 3x15 (15 per node). Each node adds two small form factor bays on its front.
Can I put SAS drives in the two bays on the node?
No. Those two SFF bays run off the Dynamic Smart Array B110i SATA RAID on the node board, and HPE's capacity tables list them with SATA drives and SATA SSDs only.
What is the maximum storage capacity of an SL4545 G7?
240.0TB on sixty 4TB drives in the 1x60 model, 200.0TB on fifty in the 2x25 and 180.0TB on forty-five in the 3x15. Solid state reaches 48.0TB on sixty 800GB LFF SATA SSDs.
Can I mix SAS, SATA and SSD drives in the same chassis?
Yes, in the large form factor section. HPE states the main storage bays take any combination of SAS, SATA or SATA SSD drives.
Do I need HPE drive carriers for an SL4545 G7?
Yes. Drives fit in HPE SmartDrive hot-plug carriers matched to the bay size, and the carrier is part of the drive assembly rather than a separate accessory.
Will a 6G drive run at full speed in this chassis?
Only if the whole path matches. HPE notes the drive, the controller, firmware and backplane should all run at the same transfer rate, or bandwidth negotiates down.
