Linux NetworX unveils ICE box 2.1

Andrea Laycock writes "SALT LAKE CITY, UTAH, March 21, 2002 - Linux NetworX announced today new and enhanced features of its award-winning cluster appliance ICE Box. The following features of ICE Box provide increased performance, high scalability and improved reliability.

-Improved Scalability ICE Box now connects multiple boxes via an IP-based virtual daisy chain for much higher reliability and scalability on systems. ClusterWorX takes advantage of this network-based communication by not requiring serial communications between boxes or the host node.

-Greater Reliability - Improved Update Procedure - In the event of a power outage, network problem or other problem while updating ICE Box, a failsafe program is implemented that will restore the ICE Box to a previously healthy state. ICE Box now buffers up to 16k of out-of-band data per node. The buffer history allows the ICE Box to store a node's console error while the administrator isn't connected.

-Faster Communication - For serial communication, 57600 was the only supported baud rate. ICE Box 2.1 now supports, 9600, 19200, 38400, 57600, or 115200 baud rates. Increased baud rates allow customers with larger systems using redundant serial to communicate more efficiently.

-Increased Control - ICE Box 2.1 has the ability to send a serial break that can access the MagicSysReq features of the Linux kernel to access the node during software failure.
