Reduce TCO through Dramatic Server Consolidation

The Schooner Appliance for Memcached/NoSQL fully exploits large, fast flash drives, DRAM, and multi-core processors with an implementation of the memcached protocol optimized for parallelism. It's delivered as a 100% memcapable compatible turnkey solution — and it's fast and handles a lot of data. So fast and big that you can replace lots of traditional servers with a single Schooner Appliance.

Here's a typical example of consolidation and the resulting reduction in the Total Cost of Ownership (TCO) which is realized by a customer with a 2-TB memcached requirement. Consolidation drives the number of servers from 32 traditional servers to 4 Schooner Appliances, coupled with a reduction in power consumption from 18 kW to 2.5 kW. TCO is reduced by 50% over three years with the consolidated Schooner solution.

The TCO comparison includes initial capital expense, maintenance, and the cost of "rack, power, and pipe" over a three-year period. The "rack, power, and pipe" estimates use rates from a typical Web hosting site. The TCO computation only includes tangible costs; it does NOT include any cost savings due to the simplified administration for an 8:1 server reduction.

This analysis is based on a configuration of 32 traditional Memcached servers with 32 GB of memory each. It uses a standard client workload with 1-kB average object size (randomized), 128-kB average key size (randomized), 95% gets (with 1 object per get) and 5% sets. Traditional Memcached servers, limited by DRAM capacity, use only about 1 Gb of network bandwidth and only a small fraction of the power of multi-core processors. The high utilization and system balance of the Schooner architecture enable the consolidation, and the power efficiency of Schooner parallel flash memory yields an eight-fold improvement in throughput per watt.
