What’s All The Fuss About Hyper-Converged Infrastructure?

Post by Anita Kibunguchy (thank you)

Technology has made it so easy that customers looking to purchase a product or service need to simply look online for reviews. Did you know that 80% of people try new things because of recommendations from friends? It’s the reason why e-commerce companies like Amazon have thrived! Customers want to hear what other customers have to say about: The product, their experience with the brand, durability, support, purchase decisions, recommendations … the list goes on. This is no different in the B2B space. That is why IT Central Station is such an invaluable resource for customers looking to adopt new technologies like hyper-converged infrastructure (HCI) with VMware Virtual SAN. Customers get a chance to read unbiased product reviews from the tech community which makes them smart and much more informed buyers.

vSphere tackles the Hyperconverged Infrastructure World: VMware VSAN 6.2

Good Post by W. Curtis Preston (thank you)

VMware is releasing VSAN 6.2, the third major release of VSAN since its introduction in August of 2014. (Like other VMware companion products, the release number is tied to the vSphere release number it is associated with.) This release gives vSphere most if not all of the major features found in other hyperconverged infrastructure products.

Peak Fibre Channel

out_of_the_fog_by_luethy-d7thzdf

Good post by Tony Bourke (thank you)

There have been several articles talking about the death of Fibre Channel. This isn’t one of them. However, it is an article about “peak Fibre Channel”. I think, as a technology, Fibre Channel is in the process of (if it hasn’t already) peaking.

There’s a lot of technology in IT that doesn’t simply die. Instead, it grows, peaks, then slowly (or perhaps very slowly) fades. Consider Unix/RISC.

Good post by Vladan Seget (thank you)

I somehow ignored this information but I think that it’s very useful to share, especially if you’re navigating the SMB or very SMB sector. In fact VMware VSAN for ROBO Two Node 10 GbE cross-connect support. So you have the possibility to cross connect ROBO nodes, via low cost 10GbE option and have a great performance because you’ll have dedicated VMkernel interface for VSAN traffic.

New Microsoft Exchange 2013 on Virtual SAN 6.1 Reference Architecture

Good post by Rawlinson Rivera (thank you)

A new Microsoft Exchange 2013 on Virtual SAN 6.1 is now available on the VMware Virtual SAN product Resource page.

This new VSAN-Exchreference architecture walks through the validation of Virtual SAN’s ability to support Microsoft Exchange 2013 designed to satisfy high IOPS mailbox configuration with Exchange Database Availability Groups (DAGs). The reference architecture is based on a resilient design that covers VMware vSphere clustering technology and Exchange DAG as well as data protection and recoverability design of Exchange Server 2013 with vSphere Data Protection and vSphere Site Recovery Manager.

Image-level backups can be done even without CBT

Good post by Luca Dell’Oca (thank you)

Lately, different bugs involving VMware CBT in vSphere 6 have created some justified concerns among users. But there are ways to guarantee successful backups even in these conditions.

Image-level backups are still the way to go

Yes, vSphere 6 is having some issues with CBT in vSphere 6.

Since its introduction back in the days of vSphere 4.0, CBT has been the cornerstone to allow fast incremental backups. CBT (change block tracking), as the name says, is a log of changed blocks of a virtual machine that vSphere registers in a file. Different data protection solutions can read this file, list which blocks have been changed since a given timestamp (usually the previous job execution), and thanks to this easily retrieve only those blocks from the storage instead of having to do a full backup every day.

A closer look at the VSAN witness appliance

Good post by Cormac Hogan (thank you)

As part of the Virtual SAN 6.1 announcements at VMworld 2015, VMware announced two new, eagerly anticipated features. The first of these is VSAN stretched cluster, allowing you to protect your virtual machines across data centers, not just racks. And the second is 2-node VSAN, which will be an excellent solution for remote office/branch office (ROBO) configurations.

VMware VSAN… and the missed opportunity

Good post by Enrico Signoretti (thank you)

One of the most interesting (among the few) announcements at VMworld was about VSAN 6.1. The product is quickly maturing and new features are being added version after version (here what’s new). And the product promises to be even better (with erasure coding and dedupe coming up in the next version!).

Virtual SAN beta coming up with dedupe and erasure coding!

Good post by Duncan Epping (thank you)

Something I am personally very excited about is the fact that there is a beta coming up soon for an upcoming release of Virtual SAN. This beta is all about space efficiency and in particular will contain two new great features which I am sure all of you will appreciate testing:

  • Erasure Coding
  • Deduplication

Getting to know the Network Block Device Transport in VMware vStroage APIs for Data Protection

Post by Abdul Rasheed (thank you)

When you backup a VMware vSphere virtual machine using vStorage APIs for Data Protection (VADP), one of the common ways to transmit data from VMware data store to backup server is through Network Block Device (NBD) transport. NBD is a Linux-like module that attaches to VMkernel and makes the snapshot of the virtual machine visible to backup server as if the snapshot is a block device on network. While NBD is quite popular and easy to implement, it is also the least understood transport mechanisms in VADP based backups.
