IBM modifies its Platform Computing Scheduler to work with OpenStack
IBM has reached into its software portfolio to provide a more
sophisticated scheduler for the OpenStack deployments it builds for its
customers.
"You don't want a cloud user to feel like their
application is not performing as advertised," said Jay Muelhoefer, IBM's
strategy director for the new Platform Resource Scheduler.
The Platform Resource Scheduler was originally developed by Platform Computing, which IBM purchased in 2012.
Platform
Computing's scheduler, originally called Platform Load Sharing Facility
(LSF), found a home in many financial analysis systems, high
performance computing (HPC) environments and in a number of grid computing deployments.
Within
an OpenStack deployment, the Platform Resource Scheduler can choose the
most appropriate server in which to place a new virtual machine based
on policies crafted by the administrator. Criteria can include how much
of each machine is already being used in terms of its CPU utilization,
memory utilization and other factors.
The software will now be included in IBM's SmartCloud Entry and SmartCloud Orchestrator,
two service offerings to help organizations build their own private
clouds. It will not be available as a separate stand-alone product,
Muelhoefer said.
The scheduler works in conjunction with the OpenStack built-in scheduler, Nova.
Nova's limitation is that "it makes decisions based on static
information. It only schedules resources once when they are initially
placed. It doesn't look how to continuously optimize the environment and
revisit the placement decisions," Muelhoefer said.
The software
also gives IBM OpenStack users a scheduler that can match the
sophistication of VMware's Distributed Resource Scheduler (DRS), found
in VMware cloud deployments.
Red Hat has also been busy improving
OpenStack's scheduling capabilities. This week, the company released
version 4 of its Red Hat Enterprise Linux OpenStack Platform, a package
that consists of the latest "Havana" OpenStack distribution, Red Hat
Enterprise Linux (RHEL) 6.5, and the Red Hat Enterprise Virtualization
Hypervisor (RHEV) . This version comes with the new Heat orchestration
engine, and a new resource manager called Foreman.
