VMWare vSAN Series – Key Features

In reference to my prior article vSAN – High Available Solution this article will give a glimpse overview of what is possibe with vSAN.

My favorite features:

Easy to install and manage. this kernel based solution requires that you have a vSphere environment already in place. Or you go the greenfield approach.

Scaleability – assign/remove single disks to/from diskgroups – go up to 64 hosts / cluster.

SPBM (Storage Policy Based Management) in place has a rich set of options assigneable to indiviual sets of VMs. Defines a redundancy with up to n+3. Furthermore, on top of it a strechted cluster is possible. A configurable IOPs limit keeps away the noisy neighbor.

In addition, Performance – literally – allflash comes with the smallest license. 

Compression/Deduplication/Encryption is sometimes required and can be activated on vSAN datastore layer.

NVME – the super fast PCIe based technology is supported. Therefore simply use this kind of SSD for Read/Write caching. 

Moreover, utilize x86 standard any vendor server hardware, no complex SAN is required for high availability. Compute, Storage and even Network … all in the box. 

Small=Big – start with an allflash two node direct design. No expensive 10Gbit+ switches have to be attached.

Certainly, integrates in Multicloud and Automation – AWS features the vSphere stack.

In conclusion, this architecture is the answer to various kinds of requirements like availability, performance, manageability, security, recoverability, compliance. However well it depends.

I appreciate your top feature in the comments!

Subsequently, I will write about the “long walk” again. Attendance Mammutmarsch  Berlin – 25.05.2019, 24h – 100km, confirmed.

After one pass and one fail (Mammutmarsch/Megamarsch Munich) the sails have been  set for another exhausting “why in the hell do I do it again” event xD.

I Wish you all the best!
