Shared Storage for my ESXI servers




Posted by CoolMike, 10-02-2014, 10:23 AM
Hi I'm running at the moment about 10 ESXI servers with local storage. I connected them with vcenter, but I'm not using a cluster. Therefore I can not use this nice features like HA or vmotion. What is the recommended way to offer HA and use vmotion? Do I need a NAS/SAN, or is the new VSAN a good solution? Michael

Hi, You will basically need a common shared storage for HA, so may be its NAS, SAN, or anything else, as long as they provide good stability and speed it may not matter what type of storage you are using. You can check what suits best per your requirements.

vSAN is a great solution, but pricing for 10+ sockets might be steep, so an iSCSI SAN might be interesting. You introduce a SPOF, but even low end units like Dell MD3 or IBM V3700 have redundant controllers and multipathing to minimize the risk of your SAN failing. If you're going the SAN route be sure to make a good estimate of how many IOPS you need and what your read percentage is so you can make decisions on RAID setup.

You need a multipathed SAN with dual controllers
