Ames, IA (1888PressRelease)
May 22, 2008 - Crystal Group tested an extended temperature configuration of their RS112 model for performance in extreme temperature environments. The in-house test was conducted as a steady state operational soak at 75C (167F) while the unit continuously executed eight instances of the Prime95 torture test. Prime95 was configured to execute small FFTs in order to exercise all 8 cores to 100% utilization. Any CPU throttling, rebooting, lock-ups or checksum errors in Prime 95 would be considered a failure.
The tested RS112 configuration passed the 2.5 operational temperature test with no failures. Righmark RMClock utility was used to log core temperature data and CPU utilization. The log data shows that the computer was fully exercising the CPUs and was able to write log data to the hard drive continuously throughout the entire test. “No failures occurred during the testing nor during exercising the CPU core, reducing the power and allowing the CPU to coast through the thermal testing. While testing at Crystal Group is extreme, we believe our servers should be working whenever our soldiers are,” stated Jim Shaw, VP of Engineering and Operations.
The RS112 with an extended temperature configuration is capable of operating in extremely high temperature environments even at full system load with no CPU throttling. This testing shows that the RS112 system can operate at 71C (160F) ambient for extended periods of time even with CPU and thermal interface variability. The RS112’s ability to remain stable at 75C ambient demonstrates that the system has plenty of cooling headroom for the most extreme operating environments, allowing Crystal Group to confidently claim a 71C operational profile for this quad-core CPU. This proves exceptional system reliability across the spectrum of thermal operating ranges. 4 Grms Vibrational Performance With Standard Rotational Drives In addition, the RS112 unit also passed 4Grms vibration testing with standard rotational hard drives. In the past, to guarantee performance in high vibration environments, solid state hard drives were used.
The RS112 unit’s rugged, vibration isolated drive carriers allow the use of 2.5 inch hard drives in vibration profiles up to 4Grms without failure. “This is very important because most customers pay ten times the cost of rational hard drives in order to buy solid state hard drives for high vibration environments,” comented Crystal Group Technical Director Jaden Ghylin. “Instead of paying $6,000 for solid state they can pay $600 for 2.5 drives.”
In environments where performance, ruggedness, and reliability are imperative, this product is an ideal fit. This specialized 1U rugged server is designed for shipboard, airborne, land-based and space based applications.
The RS112 offers extended capability with shock/vibe rating of 4 Grms in combined wheeled vehicle and aircraft profiles, a temperature range of -20C up to 71C (-4 to 160F) and multiple power options. The RS112 is available with the following processor options: Intel Xeon Core(TM)2 Duo or Dual/Quad – Core Intel 64-bit Xeon CPU. Expansion choices in this short depth (20 inches) rugged server include one (1) full-height PCI-X slot or one (1) PCle slot, meaning greater adaptability. Up to two drives and a slimline CD/DVD are available. The drives are removable and hot swappable.
All Crystal products are designed and being tested to meet MIL – STDs 810F, 167 – 1, 461E, and 901D requirements. As always, each Crystal product comes with a standard three-year warranty. Configuration Management is also available.
