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
#Topology
- worker: 8
#Disk targets
- target E:/
- number of Outstanding I/O: 16

#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
