HPE ProLiant BL2x220c G7 Hard Drives
Genuine HPE hard drives and entry solid state drives for the HPE ProLiant BL2x220c G7, new and refurbished, tested before shipping. Each of this blade's two server nodes takes exactly one non-hot-plug 2.5-inch SATA drive, so a fitted blade holds two of them, and neither can be changed without sliding the blade out of the enclosure and stopping both nodes.
BL2x220c G7 Drive Specifications
- Bays: one small form factor (2.5-inch) non-hot-plug bay per server node, two per blade
- Interface: SATA on the blade's embedded SATA controller — this server has no Smart Array option and no SAS path
- Maximum internal storage: 500GB per node, or 1.0TB across a fitted blade
- Hard drives listed: 500GB 3G SATA 7.2K rpm, 250GB 3G SATA 5.4K rpm and 120GB 1.5G SATA 5.4K rpm Entry (ETY) drives
- Solid state listed: 64GB and 32GB 1.5G SATA non-hot-plug Entry solid state drives
- Mixing: HPE's note for this server is that SAS and SATA drives cannot be mixed within it
One bay per node, SATA, and not hot-plug. Each server node takes a single 2.5-inch SATA drive on the embedded SATA controller — 500GB is the maximum HPE documents, there is no second bay to mirror to, and changing a drive means pulling the blade and stopping both nodes with it.
How much storage does a BL2x220c G7 actually hold?
| Scope | Drive bays | Maximum internal capacity |
|---|---|---|
| One server node | 1 | 500GB |
| One blade, both nodes fitted | 2 | 1.0TB |
| A full c7000 of 16 blades | 32 | 16.0TB |
That last row is the platform's point and its limit at once: 32 servers in 10U with 16TB of internal disk between them. One 500GB drive per node is a boot and scratch allocation rather than a data tier, and HPE does not support the SB40c storage blade, the PCI Expansion Blade or the Tape Blade alongside this server, so capacity past that single drive has to arrive over the network fabric.
Choosing the Right BL2x220c G7 Hard Drive
- SATA only, and one per node. The controller is the blade's embedded SATA controller and every drive HPE lists for this server is SATA, so a SAS drive is not an upgrade path here.
- There is no mirror. A single bay per node leaves no second drive to pair with, which makes resilience here a cluster question rather than a RAID one.
- Watch the link rate. The listed drives run at 1.5G or 3G SATA, and HPE notes that drive, controller and backplane all negotiate down to the slowest component in the path.
- The entry SSDs are boot-class. At 32GB and 64GB they suit a hypervisor or boot volume; the 500GB 7.2K rpm drive is the capacity choice and the largest HPE documents for a node.
- Buy in twos if the blade is being rebuilt. Both nodes leave the enclosure together, so pairing the drives while the blade is in hand saves a second outage on the other node.

The other per-node decision on this blade is memory, six slots at a time — see BL2x220c G7 memory, or the full BL2x220c G7 parts listing. The earlier double-density blades are covered under BL2x220c G6 hard drives and BL2x220c G5 hard drives, and the single-node blade of this generation under BL460c G7 hard drives. Background reading: comparing solid state and hard disk drives, understanding data transfer rate and genuine HPE drives against third-party drives. Everything else is under HPE parts by server model.
BL2x220c G7 Hard Drives FAQ
How many hard drives does a BL2x220c G7 hold?
One per server node, so two per blade. Each node has a single small form factor non-hot-plug bay, and the two nodes do not share storage.
Can I use SAS drives in a BL2x220c G7?
No. The blade uses an embedded SATA controller, and every drive HPE lists for this server is SATA. HPE's note for this server is that SAS and SATA drives cannot be mixed within it.
Are the drives in a BL2x220c G7 hot-plug?
No. Both bays are non-hot-plug. Replacing a drive means removing the blade from the enclosure, and because both server nodes sit on the one blade, that stops both of them.
Can I run RAID 1 on a BL2x220c G7?
No. There is one drive bay per node and no Smart Array controller option, so there is no second drive to mirror to. Redundancy on this platform is handled across nodes rather than within one.
What is the largest drive HPE lists for this blade?
A 500GB 3G SATA 7.2K rpm small form factor non-hot-plug entry drive. That is also the maximum internal storage HPE documents for a node, which makes 1.0TB the maximum for a blade.
Can I add a storage blade for more capacity?
No. HPE does not support the SB40c storage blade, the PCI Expansion Blade or the Tape Blade with the BL2x220c. Anything beyond the single drive per node comes over the network.
