HPE ProLiant SL4540 Gen8 Parts
The HPE ProLiant SL4540 Gen8 is the storage-dense member of the SL scale-out line: a 4.3U chassis whose middle section is all large form factor drive bays, sold as a one-, two- or three-node machine. Every part below is genuine HPE, available new and refurbished, and tested for compatibility before it ships. Live pricing for each part number appears in the tables further down this page.
SL4540 Gen8 Platform at a Glance
- Node configurations: three — the 1x60 model is one node with 60 LFF bays, the 2x25 two nodes with 25 bays each, and the 3x15 three nodes with 15 bays each
- Drive bays: 60, 50 or 45 hot-plug 3.5-inch LFF bays by model, plus two 2.5-inch SFF bays on the front of every node for boot and operating system
- Maximum internal storage: 362TB on the 1x60 model, 304TB on the 2x25 and 276TB on the 3x15, on 6TB LFF and 1TB SFF drives

- Memory: 12 DDR3 Registered slots per node — six per socket, three channels of two — to a maximum of 384GB per node
- Storage controllers: a Dynamic Smart Array B120i on each node for its two SFF drives; the LFF bays run from the node's rear I/O module on an SL4500 H220 host bus adapter or up to two Smart Array P420i controllers
- Networking: two embedded 1Gb ports per node from an Ethernet 1Gb 2-port 361i, plus two 10Gb ports when the 10G I/O module is fitted instead of the 1G module
- Expansion: one low profile PCIe 2.0 x8 slot per node, enabled by the Storage Mezzanine to PCIe Enablement Kit, and one expansion option per node
- Power and cooling: Common Slot hot-plug supplies at 750W or 1200W shared by every node, with five dual fan modules as standard
- Management: HPE iLO 4 per node on a dedicated 10/100Mb port, plus a chassis management module
Establish the node count before ordering anything for this chassis. The 1x60 is one node with 60 LFF bays behind it, the 2x25 two nodes with 25 bays each, the 3x15 three nodes with 15 each. Processors, memory and the I/O module are bought per node; the drive section, power supplies and fans belong to the chassis.

SL4540 Gen8 Parts FAQ
How many hard drives does an SL4540 Gen8 hold?
60 LFF bays on a 1x60 model, 50 on a 2x25 at 25 per node, or 45 on a 3x15 at 15 per node. Every node also carries two SFF bays on its front face.
What is the maximum storage capacity of an SL4540 Gen8?
362TB on the 1x60 model, counting 60 x 6TB LFF drives plus 2 x 1TB SFF drives on the node. The 2x25 model reaches 304TB and the 3x15 model 276TB.
How many servers are in one SL4540 Gen8 chassis?
One, two or three. Each node is an independent server with its own processors, memory, I/O module and drive bays, while the power supplies, fans and chassis are shared.
What processors does the SL4540 Gen8 take?
Up to two Intel Xeon E5-2400 or E5-2400 v2 processors per node, from a four-core E5-2407 to a ten-core E5-2470 v2. Mixing different processor models in one node is not supported.
How much memory does an SL4540 Gen8 support?
384GB per node, using twelve 32GB Registered DDR3 modules. The slots are per node, so a three-node chassis has three separate memory configurations rather than one pool.
How much rack space does an SL4540 Gen8 need?
The chassis is 4.3U. A 0.66U spacer blank makes it an even 5U, and a 13U rack adapter kit groups three chassis into 13U. HPE also specifies a rack 1200mm deep.
