4 Red Hat comparison Red Hat CPUs x86_ / /4096 MEM 128 GB 256GB/1TB 256GB/1TB 2TB/64TB Maximum 2TB 8TB 16TB 16TB filesystem size (Ext3) Maximum 16TB 16TB filesystem size (Ext4) Maximum filesize (XFS) 100TB 100TB Kernel (33,34) 34) foundation Compiler GCC 3.2 GCC 3.4 GCC 4.1 GCC 4.4

5 Benchmark AIM7 Completely Fair Scheduling (CFS) RHEL 6 also implements Transparent Hugepages (THP) to dynamically allocate x86_ MB instead of 4KB File System Scalability: EXT3 / EXT4 / XFS Faster big file deletion I/O elevator=deadline (versus CFQ default) Also noop, as. Disable I/O barriers if not needed Mount with noatime,nodiratimenodiratime

6 elevators Deadline Two queues one for read and one for write IOs dispatched based on time spent in queue CFQ (Completely Fair Queuing) Per process queue Each process queue gets a fixed time slice (based on process priority to maintain fairness) Boot command line (elevator=deadline/cfq) (l dli /f) echo deadline > /sys/class/block/sda/queue/scheduler
