How to Configure Your Server — Sizing Checklist
Servers are built to order. Answer the questions below so we can size the right configuration for you.
Step 1: Hardware Requirements
- Which server form factor do you need: tower or rackmount?
- How many CPU cores, how much RAM and how much usable storage capacity do you require?
- How many processors: single-socket (1S), dual-socket (2S) or four-socket (4S)?
- Which RAID configuration do you need? Any specific HDD or SSD type, such as 7.2K or 10K rpm drives?
- Which network interface is required: 1GbE Base-T, SFP+ or Fibre Channel?
- How many years of maintenance support do you need? (Minimum 3 years)
Step 2: Deployment & Services
- How many server units are required?
- Will you run virtual machine workloads? Do you need a VMware licence, or Windows Server with Hyper-V?
- How do you store data today? Do you have existing NAS or SAN storage?
- How do you back up today? Would you like a backup proposal, such as an IDPA 8TB appliance?
- Do you require burn-in test services?
- Do you need hard disk retention services?
Operating Systems, Management & Workloads
Operating Systems & Hypervisors
Canonical Ubuntu Server LTS, Microsoft Windows Server with Hyper-V, Red Hat Enterprise Linux, SUSE Linux Enterprise Server and VMware ESXi. Check Dell's OS support matrix for the exact versions certified on your chosen processor.

Frequently Asked Questions — Dell PowerEdge R660
Is this a fixed configuration?
No. The R660 is configure-to-order. Processors, memory, drives, RAID controller, network cards, power supplies and the support term are specified to your workload; use the sizing checklist above to brief us.
How much memory can it take?
32 DDR5 RDIMM slots for up to 8 TB, running at up to 5600 MT/s with 5th Gen Xeon processors.
How much NVMe storage fits in 1U?
Up to 16 x EDSFF E3.S Gen5 NVMe drives at the front (max 204.8 TB), or up to 10 x 2.5-inch NVMe/SAS/SATA drives, plus optional rear bays.
Can it be liquid cooled?
Yes. Direct Liquid Cooling is an option for high-wattage processors, but it needs rack manifolds and a cooling distribution unit in the data centre.
R660 or R660xs?
The R660 offers twice the memory slots (32 vs 16, up to 8 TB), processors with up to 64 cores, E3.S NVMe and liquid-cooling options. The R660xs is the cost-optimised 1U choice for mainstream virtualisation and scale-out work.
