Hello all,
Here are some results from our Netapp C-Mode system currently being put through it's paces. So far I am pretty happy with the performance, but there is still some tweaking to do before we go into production with it.
First up, results with 2x SAS 600GB 15k shelves (38 data disks):
SERVER TYPE: Win2008 R2, 1GB mem CPU TYPE / NUMBER: 1 vCPU E5540, 2.5GHz HOST TYPE: HP DL380G6, 2x E5540, 2.5GHz STORAGE TYPE / DISK NUMBER / RAID LEVEL: Netapp 3240, ONTAP 8.1.2 C-Mode/ 38X 600GB SAS 15K, RAID-DP 10G NFS through Nexus 5010 | ||||
Test name | Latency | Avg iops | Avg MBps | cpu load |
Max Throughput-100%Read | 5.30 | 11347 | 354 | 0% |
RealLife-60%Rand-65%Read | 3.70 | 11658 | 91 | 70% |
Max Throughput-50%Read | 5.10 | 11476 | 358 | 0% |
Random-8k-70%Read | 3.33 | 12590 | 98 | 73% |
Next, results using SATA drives + SSD in a Flash Pool (SSD cache in front of the SATA drives). Only 12 SATA drives in this aggregate, but will likely increase that to the full 24 drive shelf, so that should help the Real Life test result.
