The Lenovo ThinkServer RD210 (model 3796-2CU) that I reviewed is a dual-socket system that pairs quad-core power with a tiny 1U form factor. The test server came equipped with one Intel Xeon E5540 2.53GHz quad-core processor, 8GB of DDR3 RAM, and two 300GB 10,000rpm SATA hard drives. In its maximum configuration, the system supports a total of 128GB of RAM and up to 3TB of storage.
The ThinkServer RD210's front panel is configured quite differently from most other 1U rack-mounted units I’ve worked with. In addition to the standard two USB ports, the ThinkServer RD210 also boasts a front-mounted video port, a slim-line DVD-RW drive, a control panel with a slide-covered power button and warning light, and a unique pull-out diagnostic panel. This panel can definitely help you troubleshoot hardware errors without removing the system from the rack. If a yellow warning light indicates a system problem, you can pull out the diagnostic panel for more detailed information about the error's source. A series of lighted indicators identifies various system warning locations, such as the CPU, fan, and power supply.
The back of the ThinkServer RD210 provides two integrated 1GB network adapters, two USB ports, one integrated video adapter, one serial port, and one Integrated Management Module (IMM) port. There's room to install two additional NICs. Notably, there are no PS/2-style mouse or keyboard ports. Internally, the ThinkServer RD210 makes use of the Intel 5520 chip set, sports an integrated RAID controller, and provides two internal PCI Express (PCIe) slots for expansion: one 1×16 full-height half-length slot and one 1×16 low-profile slot. The system also has redundant hot-swap 675W power supplies.
You can purchase the ThinkServer RD210 with Windows Server 2008 or Server 2008 R2 Standard or Enterprise edition. The system can also be preloaded with Server 2008 SBS Standard, Server 2008 EBS Standard, or Server 2008 EBS Premium. As an alternative to the Windows Server OS, the unit can also come preloaded with Novell’s SLES for ThinkServer, with either Standard or Priority support. The server I tested came with Server 2008 R2 Standard Edition.
