ESXi 5.5 Virtualisation vs Physical Dedicated Server

6
Dec
2013

So today we faced a situation where one level 3 opened his mouth and said virtualisation only has 5% performance loss when put against a standard OS on a physical dedicated server, so we decided to put these into some real world tests. The results are shocking to say the least. Hardware Specifications: Dell Poweredge R410 Enterprise Server Dual E5520 2.26Ghz 12GB DDR3 1066Mhz 4 x 300GB 15K SAS Drives in a RAID 10 Array. Perc6/i Hardware RAID Card with BBU Operating System Setup Setup One: ESXi 5.5 with Single instance of Ubuntu Server 13.04 with VMtools Installed (All resources assigned , 2 Processors with 8 Cores – 16 Cores total & 12GB memory) Setup Two: Bare install of Ubuntu Server 13.04 We decided to run some tests that are universally available to all readers to test this themselves so we decided to use www.serverbear.com. So lets get straight into the results UnixBench Processor Results: ESXi 5.5 with Ubuntu Server 13.04 UnixBench (w/ all processors) 3620.3 Ubuntu Server 13.04 UnixBench (w/ all processors) 5316.9 We are seeing almost a 32% drop in processor performance which left a few jaws dropped! I/O Results using IOPING: ESXi 5.5 with Ubuntu Server 13.04 I/O Seek Test (No Cache) – 7420 iops, 29.0 mb/s I/O Reads – Sequential – 1825 iops, 456.3 mb/s I/O Reads – Cached – 370452 iops, 1447.1 mb/s Ubuntu Server 13.04 I/O Seek Test (No Cache) – 9520 iops, 37.2 mb/s I/O Reads – Sequential – 2286 iops, 571.6 mb/s….

SSD RAID 10 IOPS Testing

SSD RAID 10 IOPS Testing – H700 Perc RAID Card Testing R710 Recently we’ve been playing with H700 RAID cards with SSD’s. We have had some issues which will be outlined in future follow up posts with SSD’s & H700 Compatibilities. 6 x 256GB Crucial M4 Firmware 0309 all confirmed in a RAID 10 array. Testing tool : Fio 1.38 64bit Fio is quite easy to configure and setup in all major linux distribution. We are testing it on Debian which is quite easy to install J  From CLI (command line interface) just run the following commands: This will update the Package Index. The APT package index is essentially a database of available packages from the repositories defined in the /etc/apt/sources.list file. To update the local package index with the latest changes made in repositories, root@server:/# Apt-get update This command will then install FIO from the remote repositories & any dependencies root@server:/# Apt-get install fio We then want to create the actual configuration file which will have all the variables for this test , because we are utilising SSD’s it’s a good idea to setup the configuration file with the following settings The easiest way to create the configuration file is like this: root@server:/# nano random.fio Then you want to paste the following in: [random] rw=randread size=1g directory=/iops iodepth=403 direct=1 blocksize=4k numjobs=16 nrfiles=1 group_reporting ioengine=sync loops=1 The second last step is to create a folder where all the working/testing will take place in , in our case we created /iops….
