A little over six months ago I started researching the quickly emerging world of “Hyper-converged” infrastructure as a new IT ethos to take my company’s IT operations into the next decade of application and data hosting. I was first introduced to the idea when I attended a webinar from Simplivity, one of the leading companies […]
Making use of a SAN (storage area network) provides some incredible benefits. I won’t go into depth but at a high-level you often get: 1. Excellent hardware redundancy for data storage, more-so if you are using multiple arrays but even most enterprise single arrays can provide N+1 redundancy. Now we can tolerate power failures, and […]
I have been fiddling about with setting up a SQL Server 2012 Failover cluster using an Equallogic SAN. After a whole lot of digging about I found two different posts on two different sites which got me about 90% of the way there. However there were some key “gotcha’s” and other information that was missing […]
I had a VM using RAW storage format on a ZFS storage object. I needed to delete the RAW hard drive files but couldn’t find them and the “remove” button was greyed out. One post mentioned using “qm rescan” which then allowed the poster to use the remove button but that didn’t work for me. […]
If you load Proxmox 4.0 from OVH or any of their affiliates you end up with a partition scheme that gives you one big logical volume for data that is formatted to EXT3. That will work but it isn’t desirable. Starting with Proxmox 3.4, support for the ZFS filesystem was added. ZFS is more than […]
So part of my “poor-man’s hyper-v cluster” experiment in my home office here has led me to start looking into storage options for virtual platforms. Hyper-V is apparently quite flexible, however fail-over clustering limits your options. So for those of you who are just joining us I am doing research on clustered Hyper-V for work. […]
