Part 2: My take on PernixData FVP 2.0

2 Comments

In the blog post Part 1: My take on PernixData FVP I mentioned the release date on FVP version 2.0 to be very soon. Well… PernixData went GA status with FVP 2.0 on the 1st of October.

I liked the announcement e-mail from Jeff  Aaron (VP Marketing at PernixData) in which he first looks back at the release of version FVP 1.0 before he mentions the new features within FVP 2.0:

FVP version 1.0 took the world by storm a year ago with the following unique features:

  • Read and write acceleration with fault tolerance
  • Clustered platform, whereby any VM can remotely access data on any host
  • 100% seamless deployment inside the hypervisor using public APIs certified by VMware.

Now FVP version 2.0 raises the bar even higher with the following groundbreaking capabilities:

  • Distributed Fault Tolerant Memory (DFTM) – Listen to PernixData Co-founder and CTO, Satyam Vaghani, describe how we turn RAM into an enterprise class medium for storage acceleration in this recent VMUG webcast
  • Optimize any storage device (file, block or direct attached)
  • User defined fault domains
  • Adaptive network compression

 

We will take a look at PernixData FVP 2.0, how to upgrade from version 1.5 and explore the newly introduced features…

Having posted an article on Software Defined Storage a short while ago, I want to follow up with some posts on vendors/products I mentioned.

pernixdata

First of all we’ll have a closer look at PernixData. Their product FVP, stands for Flash Virtualization Platform, is a flash virtualization layer which enables read and write caching using serverside SSD or PCIe flash device(s). Almost sounds like other caching products which are out there, don’t it… Well, PernixData FVP has features which are really distinctive advantages over other vendors/products. With a new (2.0) version of FVP coming up I decided to do a dual post. Version 2.0 should be released very soon.

What will FVP do for you? PernixData states:

Decouple storage performance from capacity

So what does that mean? Well, it means we no longer must try to fulfill storage performance requirements by offering more spindles in order to reach the much demanded IOPS. Next to that we must try to keep a low as possible latency. Doing so, what better place for flash to reside on the server! Keeping the I/O path as short as possible is key!!
When storage performance is no longer an issue, capacity requirements are easily met.

vSphere Flash Read Cache (vFRC)

Recently I started studying for my second VMware VCAP exam. It made sense to plan the updated VCAP550-DCA exam, since vSphere 5.5 is among us for quite some time now.

vFRC

While doing so, you automatically run into vSphere Flash Read Cache (vFRC). A feature provided since vSphere 5.5 (only in the Enterprise+ bundle), but I never got to configure and/or test it. Hence this little write-up…

Running through the blueprint for VCAP550-DCA, you’ll see it listed under section 1, objective 1.1:

Section 1 – Implement and Manage Storage
Objective 1.1 – Implement Complex Storage Solutions

Skills and Abilities

  • Determine use cases for and configure VMware DirectPath I/O
  • Determine requirements for and configure NPIV
  • Understand use cases for Raw Device Mapping
  • Configure vCenter Server storage filters
  • Understand and apply VMFS re-signaturing
  • Understand and apply LUN masking using PSA-related commands
  • Configure Software iSCSI port binding
  • Configure and manage vSphere Flash Read Cache
  • Configure Datastore Clusters
  • Upgrade VMware storage infrastructure

Let’s check it out!!

SDDC: VMware announces EVO:RAIL

1 Comment

With VMworld 2014 just kicking off, VMware already made an awesome, and somewhat unexpected,  announcement being VMware EVO:RAIL!!!
EVO:RAIL seems to be the first product in the EVO family, so it looks like VMware probably got more surprises up their sleeves in the near future.

Let’s take a quick look at this new product range and what it’s first family member RAIL is all about…

SDS: Software Defined Storage solutions

SDS

Software Defined everything. Still a very hot item in the ever strong developing IT landscape.

In the year 2012 ‘Software Defined’ looked like just another buzzword, but the market is changing direction more and more towards software defined solutions. The Software Defined Data Center (SDDC) is nowadays supported by Software Defined Storage (SDS), Software Defined Network (SDN) and security solutions. All very cool stuff!! I want to take a closer look at SDS in this blog post.

So…What is Software Defined Storage? Everybody has an idea on what it should be. My idea of SDS matches the quote below:

Software-defined storage (SDS) is the process of using software-based techniques to create, deploy and manage storage resources and infrastructure. It enables abstracting or separating storage services from hardware devices by using software or programmatic access to extract and manipulate storage resources

PowerCLI: provisioning a single vSphere host

Last week I was working on an environment running VMware vSphere Enterprise licenses. The job at hand was to expand the compute environment with some new blades. Due to the lack of host profiles, I wanted to be able to provision a new host with all the necessary datastores from CSV and all the correct vSwitch settings.

The scripts connects to vCenter, and asks which vSphere host you want to provision using their hostname. I used 2 functions; The first is used to configure the vSwitch settings, the second to configure the NFS advanced settings along with creating the datastores from a CSV file.
