WiMAX base stations run Linux, use in-memory database

Mar 21, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive

McObject says its in-memory database was selected by Soma Networks for use in a line of Linux- and VxWorks-based WiMAX base stations. The eXtremeDB-HA (high availability) database will provide real-time, fault-tolerant storage and retrieval of network traffic routing data in Soma's FlexMax Mobile WiMAX… base stations, according to McObject.

The FlexMax base stations comprise one component of Soma's line of WiMAX products. Soma says the devices support many different licensed frequency spectrums, integrate with IMS (IP multimedia subsystems) and other IP-based applications, and incorporate multi-antenna technologies such as MIMO (multiple in, multiple out) and AAS (adaptive antenna systems, aka “beamforming”). One compact FlexMax model, the NPM 2000 (pictured above), is said to offer “non-line of site” (sic) subscriber gateway broadband wireless services at distances of up to 9.9 miles (16km).

McObject claims that Soma chose eXtremeDB-HA after pre-development testing suggested its performance edge over competing products rose as the number of data elements increased. According to Scott Woodworth, Soma's SVP of operations, “All-in-memory responsiveness, and intuitive C/C++ application programming interface drove the choice.”

McObject CEO Steve Graves added, “eXtremeDB-HA meets [carrier grade requirements] via deployment of multiple fully synchronized eXtremeDB databases within the same hardware device or across multiple, widely distributed systems. With synchronous (2-safe) and asynchronous (1-safe) replication, and a host of other options, developers have the flexibility to configure eXtremeDB-HA to exactly match requirements.”
