The X-Series started with a single special order rugged small Red Hat Linux server which was ordered for a one-off military application. The main contractor liked it so much they asked if we could make it rack mountable and easily replaced. A few months later and the first X-Series Multi-Module Chassis was born.
Although the original stand alone X1 is still available it is not truly a member of the X-Series products but can provide a compact ruggedized desktop device compatible with X-Series modules installed in the rack mounted chassis.
The X-Series was originally designed around the X10 which has 10 modules, 5 in the front and 5 in the back, fits into 5RU of a 19 inch rack only 20 inches deep and provides very good military grade computing power density. However most customers have chosen the X5 which houses 5 X-Series modules in 5RU of a 19 inch rack only 11 inches deep. This makes the X5 a good fit for compact airborne and bulkhead or rack mounted shipborne use. The X2 houses 2 modules mounted horizontal in 2RU of a 19 inch rack 11 inches deep.
X-Modules have low power consumption (<150W/module) yet pack a punch with options that include third generation (Ivy Bridge) Intel Quad Core i5 processors and can be configured with Windows Hyper-V virtual operating systems supporting multiple simultaneous Windows or Linux servers or PCs. Each individual module has its own power supply and does not rely on a back-plane, so twist the 4 hand nuts and you can replace any module under power in less than 2 minutes. This design not only provides simple and fast repairs for front line operations, it also provides a method of upgrading software or hardware without the need for highly skilled technicians in the field.
