The Waltham, Massachusetts-based Linux and identity management vendor team up with real-time specialist Concurrent Computer Corp in January to create SLERT via extensions to the core SLES operating system.
With the technology now generally available it is clear that SLERT is literally an extension to SLES 10 and piggy-backs on the standard operating system variant. According to Novell, if SLERT users do not have an existing SLES 10 subscription, they will have to take one out.
A SLERT subscription for up to 32 CPUs costs $2,500 if you already have a spare SLES subscription, and $2,895 per server per year if you do not. For that you get the additional software as well as maintenance and security patches.
As previously reported, SLERT is only available for x86 and x64 processor architectures at this time, and includes functionality designed to enable SUSE Linux to be used in real-time applications, such as trading floor applications in the financial services market.
According to Novell, tests with the open source Ingres database showed that SLERT had an average response time one-third of standard Linux distributions when dealing with 16 simultaneous threads of database queries.
SLERT is available now from Novell and Duluth, Georgia-based Concurrent, which already offers its own RedHawk real-time environment based on Novell rival Red Hat Inc’s Enterprise Linux.
