Why ARM Servers, And Why Now? (EnterpriseTech)
Timothy Prickett Morgan takes a look at how the ARM server ecosystem is coming along. "As Canonical announced two weeks ago, Ubuntu Server 14.04 LTS is the X-Gene 1 from Applied Micro and the Thunder from Cavium Networks. Red Hat has demonstrated its Fedora development Linux on the X-Gene 1 and AMD’s “Seattle” Opteron A1150 processors, and Jon Masters, chief ARM architect at Red Hat, said at the ARM Tech Day that 98.6 percent of the packages in RHEL are “ARM clean,” and added that this is a full-on 64-bit implementation of the stack and that Red Hat would not support 32-bit code and that the support for 64KB memory pages made it impossible to do a 32-bit port. That said, you can always load a virtual machine with a version of Linux that does support 32-bit code if you need to, said Masters. Red Hat will not comment on when or how ARM support will be available with the commercial-grade Enterprise Linux, and a lot depends on the availability of hardware that supports various standards (UEFI and ACPI for instance), demand from customers, and the readiness of key programs such as Java. SUSE Linux has added support for ARM chips in the openSUSE development version and is very likely shooting to have ARM support in Enterprise Server 12, due to go into beta maybe later this year for production next year."
