The Dell PowerEdge R720 (service tag/serial number 35K1621) with 16 × 2.5-inch SFF disk bays, 1 × Intel Xeon E5-2665 CPU, and 80 GB RAM is a 2U rack-mount enterprise server from Dell's 12th-generation PowerEdge family (launched 2012). This is a very common, highly configurable platform that was widely deployed for virtualization, databases, file serving, web/application hosting, backup targets, and general-purpose workloads throughout the 2010s and early 2020s.

The PowerEdge R720 is a dual-socket 2U rack server based on the Intel Xeon E5-2600 v1 (Sandy Bridge-EP) architecture. Your configuration includes:

  • Chassis: 16 × 2.5-inch SFF (Small Form Factor) hot-swap drive bays (supports SAS/SATA HDDs/SSDs; optional 8 × 3.5" LFF config available but this unit is SFF)
  • Processors: 1 × Intel Xeon E5-2665 (8 cores / 16 threads, 2.4 GHz base clock, 3.1 GHz turbo, 20 MB L3 cache, 115W TDP) → Single-CPU config (second CPU slot empty — can be upgraded to dual E5-2600 v1/v2 series)
  • Memory: 80 GB DDR3 ECC Registered RDIMM (likely 10 × 8 GB or 5 × 16 GB DDR3-1333/1600 modules; maximum supported 768 GB with 24 DIMM slots)

This server offers excellent balance of compute, memory, storage, and I/O for its generation. The 16 SFF bays provide flexible storage options (e.g., high-IOPS SSDs for boot/OS/performance tier + high-capacity SAS/SATA for bulk data). The embedded PERC RAID controller (typically PERC H710 or H710P in this era) supports RAID 0/1/5/6/10/50/60 with optional battery-backed cache.

Networking and expansion are strong:

  • 4 × 1 GbE embedded NICs (Broadcom or Intel-based)
  • Up to 7 × PCIe 3.0 slots (depending on riser configuration)
  • iDRAC7 (Integrated Dell Remote Access Controller 7) with dedicated management port for full out-of-band remote management (KVM, virtual media, power control, monitoring)

The R720 runs VMware ESXi, Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux, Ubuntu, Oracle Linux, or older OSes — with full Dell validation for virtualization hypervisors and enterprise applications.
