#VDI Calculator v5 is Now Available with Major New Features – #IaaS, #Storage, #BYOD via @andreleibovici

This is awesome! Great work by @andreleibovici!

I am happy to announce the General Availability of the new VDI Calculator v5. This new version is the single biggest release since I started delivering the calculator. I have completely re-architected the way the calculator works, allowing multiple types of desktops to be configured in a single calculation for a single solution.
 
All existing features have been retained and will work in the exact same way you are used to, but you now have the ability to select different  options for different types of desktops or desktop pools.
 
As an example, you may choose Desktop Type 1 to be a ‘student’ desktop using Linked Clones with 10 different pools; conversely you may choose Desktop Type 2 to be a ‘professor’ desktop using Full Clones with 5 individual pools. This new calculator gives you much more granular control over your calculations eliminating repetitive tasks when sizing larger environments.
 
To enable multi-desktop pool calculations just select ‘-’ and ‘+’ in the top bar menu.

Another additional feature is what I call ‘Ask for Help‘. During the application session when you select the Update option a new screen will show up asking if you would like to be contacted by VDI solutions vendors that can help reduce costs, improve performance or improve manageability of your VDI solution. If you are interested…

Under the Covers of a Distributed Virtual Computing Platform – Built For Scale and Agility – via @dlink7, #Nutanix

I must say that Dwayne did a great job with this blog post series!! It goes into expelling the Nutanix Distributed File System (NDFS) that I must say is the most amazing enterprise product out there if you need a truly scalable and agile Compute and Storage platform! I advise you to read this series!!

Under the Covers of a Distributed Virtual Computing Platform – Part 1: Built For Scale and Agility

Lots of talk in the industry about how had software defined storage first and who was using what components. I don’t want to go down that rat hole since it’s all marketing and it won’t help you at the end of the day to enable your business. I want to really get into the nitty gritty of the Nutanix Distributed Files System(NDFS). NDFS has been in production for over a year and half with good success, take read of the article on the Wall Street Journal.

Below are core services and components that make NDFS tick. There are actually over 13 services, for example our replication is distributed across all the nodes to provide speed and low impact on the system. The replication service is called Cerebro which we will get to in this series.
Nuntaix Distrubuted File System

 

This isn’t some home grown science experiment, the engineers that wrote the code come from Google, Facebook, Yahoo where this components where invented. It’s important to realize that all components are replaceable or future proofed if you will. The services\libraries provide the API’s so as newest innovations happen in the community, Nutanix is positioned to take advantage.

All the services mentioned above run on multiple nodes in cluster a master-less fashion to provide availability. The nodes talk over 10 GbE and are able to scale in a linear fashion. There is no performance degradation as you add nodes. Other vendors have to use InfiniBand because they don’t share the metadata cross all of the nodes. Those vendors end up putting a full copy of the metadata on each node, this eventually will cause them to hit a performance cliff and the scaling stops. Each Nutanix node acts a storage controller allowing you to do things like have a datastore of 10,000 VM’s without any performance impact… continue reading part 1 here

No it’s not Billy Gibbons, Dusty Hill, or drummer Frank Beard. It’s Zeus and Zookeeper providing the strong blues that allow the Nutanix Distributed File System to maintain it’s configuration across the entire cluster. Read more…

#Windows server 2012 Storage Spaces – using PowerShell – via LazyWinAdmin

Very good work on this blog post about Windows Storage Spaces!

WS2012 Storage – Creating a Storage Pool and a Storage Space (aka Virtual Disk) using PowerShell

 

In my previous posts I talked about how to use NFS and iSCSI technologies hosted on Windows Server 2012 and how to deploy those to my Home Lab ESXi servers.

One point I did not covered was: How to do the Initial setup with the physical disk, Storage pooling and the creating the Virtual Disk(s) ?

The cost to acquire and manage highly available and reliable storage can represent a significant part of the IT budget. Windows Server 2012 addresses this issue by delivering a sophisticated virtualized storage feature called Storage Spaces as part of the WS2012 Storage platform. This provides an alternative option for companies that require advanced storage capabilities at lower price point.

Overview

  • Terminology
  • Storage Virtualization Concept
  • Deployment Model of a Storage Space
  • Quick look at Storage Management under Windows Server 2012Identifying the physical disk(s)
    • Server Manager – Volumes
    • PowerShell – Module Storage
  • Creating the Storage Pool
  • Creating the Virtual Disk
  • Initializing the Virtual Disk
  • Partitioning and Formating

Terminology

Storage Pool: Abstraction of multiple physical disks into a logical construct with specified capacity
Group of physical disks into a container, the so-called storage pool, such that the total capacity collectively presented by those associated physical disks can appear and become manageable as a single and seemingly continuous space.

There are two primary types of pools which are used in conjunction with Storage Spaces, as well as the management API in Windows Server 2012: Primordial Pool and Concrete Pool.

Primordial Pool: The Primordial pool represents all of the disks that Storage Spaces is able to enumerate, regardless of whether they are currently being used for a concrete pool. Physical Disks in the Primordial pool have a property named CanPool equal to “True” when they meet the requirements to create a concrete pool.

 

Concrete Pool: A Concrete pool is a specific collection of Physical Disks that was formed by the user to allow creating Storage Spaces (aka Virtual Disks).
