iometer

利用iometer去測量GlusterFS

在CAKE環境下的效能

Server HostName CAKE配置 對內(mgmt) 對外(web)
No.30 c1 Center+Node 192.168.10.10 140.92.25.126
No.29 n1 Node 192.168.10.11 140.92.25.238
No.32 n2 Node 192.168.10.12 140.92.25.229

使用三台server, 每一台server有一個RAID 6, 當作一個單一的brick使用
所以總共有3個brick,組成DHT或是striped volume

(per server in a single raid 5, serving a single brick, across 3 servers in a DHT and striped setup)

不含tuning volume options


upload .img to CAKE center

create a VM for test iometer (on cakeweb)
Management -> Virtual Machine -> Create New
#Computing Resources
vCPU number 8 (vCPU)
Memory Size 8192 (MB)

set the VM (on cakeweb)
Hardware Info. -> Disk -> DISK BUS TYPE: virtio
Hardware Info. -> NIC -> NIC TYPE: virtio

create a virtual disk for the VM and attach it
Management -> Virtual Disk -> Create New -> size: 30 (GB)
Management -> Virtual Disk -> List -> Operation (Attach)

open the VM and set iometer

#Test setup

  • run time: 2 min
  • ramp up time: 20 s

執行的時候記得點group之後再執行

否則會只跑到一個worker


同個環境設定跑三次
