When it was launched at the end of 2011, the Proliant DL120 G7 was an attempt by HP to try and convince small and medium-sized businesses (SMBs) to move away from tower to rack-mounted servers.
One might argue that not all SMBs have racks on their premises, but wall-mounted or even 21U floor standing ones make a lot of sense when you factor in other crucial business connected products such as on-premise firewall or 24-ports switches.
The DL120 G7 is a single-socket 1U server which HP says is ideal for single-application IT infrastructure, web and edge-of-network (i.e. end user) applications. It is deep at 70cm and offers some cracking expansion capabilities.
There's four 3.5-inch bays that can accommodate optional hot-swappable drives, HP's Smart Array B110i SATA controller (offering RAID 0/1 and 0+1), an optional DVD drive, four DDR3 memory slots (up to 32GB in all), six USB ports, two PCI express slots, two NIC connectors and HP's Integrated Lights-Out device management solution.
This is essential for any system administrator looking for beyond-basics remote access functionality (including monitoring, controlling and diagnostics).
The model examined in the slidehow had two redundant power supply units and an Intel Xeon processor - probably a Sandy-Bridge based one like the E3-1220 which was used in the entry-level models.
