1. Batch nodes from FY15 is online and in service - OpenStack 16 vCPU VMs. Need reconfigure the disks from raid-1 (mirror) to raid-0 in order to have larger /scratch space and IOPS.

2. Though we are running more jobs than the number of slots we purchase, there are still quite some free batch slots that we can use. But we don't seems to get pilots/jobs fast enough. Need to understand the reason.
