"Dell EMC Unity 300 Hybrid Flash" Storage on Oracle Lynux 6.9 SCSI device parameter settings for Ora

edited May 28, 2017 8:13PM in Linux Operating System (MOSC) Question

Hello!

I have same  installation problem with new  "Dell EMC Unity 300 Hybrid Flash" Storage on Oracle Lynux 6.9 SCSI device settings.

I want to get the best performance from the array for productive Oracle database.

I use Oracle ASMlib to create ASM Disks.

I checked the communication settings for Oracle Linux SCSI device of "Unity 300 Hybrid Flash" and the parameter optimal_io_size made me doubt:

cat /sys/block/dm-2/queue/optimal_io_size

33553920

cat /sys/block/dm-2/queue/minimum_io_size

8192

cat /sys/block/dm-2/alignment_offset

0

cat /sys/block/dm-2/queue/physical_block_size

512

cat /sys/block/dm-2/queue/logical_block_size

Howdy, Stranger!
