Reading Time: 5 minutesNow that I’m back from the VMworld US 2015, I can point some takeaways from this trip and give my event’s impression.
First to all why an European should attend at the US edition of the VMworld? Simply because this one is the real VMworld: huge, epic, a real American event! Probably too much big and too much crazy, but sometimes is nice feel and see the difference.
Reading Time: 2 minutesEVO:RAIL is scalable and modular architecture housed in a small form factor (2U/4N Form factor including compute, storage, network and management resources), with flexible hardware configuration (with 8 Global Qualified EVO:RAIL Partners), able to scale out up to 16 appliances (64 nodes).
In only one year of history it has grow more and more in capabilities and also in adoption. But also in version 1.2 was still based of vSphere 5.5 and VSAN 1.0, until now!
Reading Time: 2 minutesThe new Virtual SAN 6.1 has also another new features related to a specific deployment scenario: a 2-Node Remote Office Branch Office (ROBO) configuration.
This configuration was possible with the previous VMware product (VSA) but was not suitable with VSAN, making space for other solutions like StorMagic SvSAN or StarWind Virtual SAN.
Reading Time: 3 minutesVMware Virtual SAN 6.0 (formally was v2.0) was a big improvement of the VMware’s hyperconverged storage solution with some important new features like the new filesystem (with powerful snapshot implementation), the concept of fault domain (to improve data resiliency), more scalability and the full flash option.
Now VMware has announced a new release: Virtual SAN (or VSAN) 6.1, with new improvements, including enhanced usability & management, advanced troubleshooting, and several new features.

Like in 2012, this year I choose to attend at the US edition of VMworld. I like it in 2012, and probably I would like also this year.
Is really different from the European one and sometimes (travels are too costly for European people) deserve a visit.
This will be my second VMworld US and I’m really curious and exited! Will be also a VMworld without a new vSphere release (or I least I’ve not seen any beta)… things are changing… new products, new strategies!
I’ve already written about my expectation and I hope that will be a great and intensive week.
Reading Time: 3 minutesVMware snapshots are widely used for different purpose, but the main reason why they exist in vSphere is to help backup programs: using VADP a backup can start a VM snapshot in order to have a frozen file, copy it (or copy only the changed block with CBT and virtual hardware 7 or greater) and then release the snapshot.
Other usage are to have a just in point rollback during patches or big changes, but a recommended practice is to release the snapshot as soon as possible.
Large snapshots or broken or invalid snapshots are common issues in VMware virtual environments. And monitor the snapshots size it’s a must!
