vSAN Stretched Doesn't Always Mean 2x the Capacity
I get questions every now and then around sizing capacity requirements for vSAN Stretched Clusters. Many have written extensively around how much capacity is required. Time to clear some myths!
First Look : Installing / Upgrading vCenter Server Appliance (VCSA) 6.7
I'm sure everyone is aware of the recent vSphere 6.7 launch a couple of days back. It is literally plastered all over social media (at least on my news feed). I have put together a few screenshots of the new installation/upgrade process for vCenter Server Appliance (VCSA) 6.7, for those who are interested.
HCI Scares Us... The Storage Admins
What scares us storage admins most about hyper-converged infrastructure? Is it all unfounded?
I have always been a massive fan of PDAs and have used generations of Palm Pilots from the Palm iiiC to the Palm V and the Tungsten series. Even tried the Handspring platform that tried to disrupt the market then.
How Long Does It Take To Recover From vSAN Drive or Node Failures?
It is perhaps a valid question to ask any storage vendor "How long before storage comes back to normal status after failure?"

However, it is an extremely difficult question to answer, influenced by various factors.
Surviving 63 Drives Failure on vSAN
One of the most common discussion topics around vSAN is around availability. There are also a lot of misconceptions and FUD (fear, uncertainty and doubts) around this topic. What better way to debunk it by doing a little test on failures!

Big fan of William Lam's PowerCLI script for deploying multiple Nested ESXi VM's for demo and POC purposes (link). Had to tweak it slightly for what I wanted it to do.
