Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers


[ Thanks to LinuxDevices.com for this link. ]

"In spite of Red Hat's perceived image as "the Linux company," the company continues to promote eCos as a light weight and highly configurable alternative to Linux, for deeply embedded applications. Red Hat's ongoing eCos commitment surfaced yesterday in the form of a joint announcement between Red Hat and CrosStor Software. CrosStor, it seems, is porting its network-attached storage (NAS) software -- which currently depends on Wind River's VxWorks as its underlying RTOS platform -- to Red Hat's eCos."

"According to CrosStor CTO Gordon Harris, CrosStor requires an embedded RTOS for a number of basic system functions, including a hardware abstraction layer (HAL), precision scheduling, and timers. Although the company is currently a licensee of Wind River's VxWorks RTOS, Harris says "eCos is very attractive." The port of CrosStor to eCos is already in process and will be released before the end of this year."

"Linux itself was not a viable alternative, Harris explained, "because [Linux] brings general purpose operating system baggage" that is not appropriate for the highly specialized file system and RAID technology requirements of CrosStor's network-attached storage application. "eCos is much more light weight," said Harris. Using Linux with real-time extensions such as RTLinux was also not viable, according to Harris, because although "RTLinux is really good for data collection," it does not offer the specific real-time services, such as scheduling and timers, that are required by CrosStor's application."
