A step up from the RD530 is Lenovo's ThinkServer RD630, which offers the same 16 Intel Xeon E5-2600 processor cores, 2 TB of hot-swap storage, 320 GB of 1,333MHz DDR3 memory, quad-port and 10 Gbit Ethernet options and redundant power supply capabilities, plus more of the storage options available to a 2U enclosure for a list price of $2,699.

Both new ThinkServers also offer Lenovo's SmartGrid power management technology, which simultaneously monitors the power usage of as many as 1,000 servers and can implement power-saving policies that Lenovo claims can increase efficiency by as much as 45 percent from its prior server generations.
