PernixData FVP 2.0 Now Available

It is here! PernixData FVP 2.0. During the last couple of months I have been getting experience with this in my lab and at selected customers. In 2.0 we are introducing 4 new groundbreaking capabilities.

Distributed Fault Tolerant Memory (DFTM):

Now we support the use of RAM for read and write acceleration. We still support the use of flash of course. We are just giving extra options for acceleration. From my experience in my lab RAM is INSANELY fast. It did not matter what kind of IO I threw at it. It just consistently performed with extremely low latency. Just imagine reading and writing data from RAM with 0,08 millisecond!

NFS support

This one does not require a lot of explanation. Now we support NFS datastores. It is implemented in the same transparent fashion as block storage. So absolutely no changes is made to the VM or NFS datastore.

User defined fault domains

With the use of RAM we also see the need to define your fault domains. If you are using RAM for Write acceleration you would probably like to have a copy of the Writes on a second host placed in a another RACK/Blades chassis/Datacenter. With fault domains you can now define your physical boundaries and make sure exactly where the writes are replicated to. This of course also works with flash.

Adaptive Network Compression

When we send the Writes over the PernixData network (default is vMotion but any vmkernel will work, you decide) we have seen in 1Gb environments that it can be a problem. In FVP 2.0 we will take a look at the data to be sent, and if it makes sense we will compress before we send it over the wire. This brings down the latency of WB +1/+2 policy in a 1Gb environment.

PernixData Nordic Roadshow with Frank Denneman

If you are from Scandinavia this post is for you, please read on

I am happy to announce the PernixData together with Arrow ECS will be having morning seminars in Copenhagen, Oslo, Stockholm and Helsinki. The topic is using flash in the datacenter and where should it belong.  We have been so lucky to have Frank Denneman visit the Nordic’s and share his insightful perspective

The schedule for the week:

September 15th: Copenhagensign up
September 16th: Oslosign up
September 17th: Stockholmsign up
September 18th: Helsinkisign up

What is the seminar about

Using storage arrays for both performance and capacity is regarded as a natural design by many. This is easy, but almost always introduces issues with storage performance, regardless of the environment size.

Flash storage is seen as savior to storage I/O bottlenecks, but implementing flash can be confusing. Should it go in your SAN? Servers? Both? Furthermore what key features (e.g. write acceleration, clustering, etc.) are required to turn flash into an effective tool for accelerating storage performance across an entire data center?

Join us for this talk where Frank will highlight:

  • Pros and cons of various flash deployment methodologies
  • Best practices for using flash to accelerate storage performance
  •  How to measure results and ROI

We look forward to seeing you there!

VeeamON 2014 Conference

It is almost unbelievable. I remember 7 years ago when I was using Veeam FastSCP to transfer files to/from my ESX servers and Vizioncore vRanger was the program to use for Backups in a virtual environment. Now 7 years later no one talks about vRanger and Veeam is almost the de-facto standard for backups in a virtual environment. Veeam has more than 100.000 customers world wide and now they are moving to the next level by having their own backup and availability conference VeeamON in Las Vegas.

This is a huge accomplishment and it all came by having a great product, that simply worked and did what it should in a great but simple manner.

If you want to know what is going on the virtual world when it comes to availability you should spend your days at the Cosmopolitan in  Las vegas October 6th till October 8th.

If you are a current Veeam customer and want to improve the way you leverage their product click the picture below and sign-up! I highly recommend it.

Netgear R7000 – Insane wireless performance

I have been running a WRT320N wireless router for the past few years. It has been rock solid and had no problem handling my 60/60mbit internet connection when using wired clients. The router was not so great at the wireless speed though. I have been running custom DD-WRT firmware on the router, because I like all of the customizations and possibilities it gives.

I decided it was time for look for a new router with good wifi. I live in an apartment complex so the air is crowded with accesspoints running in the 2.4ghz range. When checking the 5ghz range I did not find any other wireless networks. I eventually came out with the following requirements:

– Dual Band router. It should do 2.4GHZ and 5GHZ at the same time.

– Support all wireless generations B/G/A/N/AC

– Work stable with DD-WRT firmware

– Gigabit Switch

After a little research I quickly discovered the Netgear R7000. It was the number one router on smallnetbuilder.com in the AC1900 category. I moved on to the DD-WRT firmware and people stated it was stable with the “kong” builds. By looking at the specs and the forum this seemed like the perfect fit. I decided to give it a go and bought it right away.

When the router arrived the first thing I did was to flash it with DD-WRT Kong Build 24200. It was extremely simple, done through the web interface.

I configured the wireless networks and created:

– One 2.4 ghz network in “mixed mode”

– One 5 ghz network in “N/AC” mode

I then decided to test the wireless speed on both with speedtest.net. On the 5ghz network I instantly pulled 60mbit down and up! Hurrah! Finally the internet was my limitation and not the wireless network. I tried connecting to the 2.4ghz and I did not see the same performance. As I mentioned my neighbourhood is extremely crowded with wireless network and this hurts performance.

I then tried to copy some files from my local synology nas to my laptop and I experienced 20MB/sec! On my old router I used to see 4MB/sec on a very good day.

All in all, if you are looking for great wireless performance and something highly customizable but stable, then look no further than to the Netgear Nighthawk R7000 and flash it with DD-WRT

Featured: Book Review – Learning Veeam Backup & Replication for VMware vSphere

This is a featured blog post by Mads Fog Albrechtslund orginally posted here

If you want to check out Veeam Backup Go here: http://www.veeam.com/vm-backup-recovery-replication-software.html

Disclaimer: I have received this book as a free review sample, with the only requirement that I would write a review of it here on my blog and post short reviews of it on amazon.com, goodreads.com and books.dzone.com. These should be unbiased and I was in no way obligated to write positive reviews.

Learning Veeam Backup and ReplicationThe book is available in both eBook and Print versions from Packt Publishing

I know Christian Mohn, the author of “Learning Veeam Backup & Replication for VMware vSphere” from Twitter (@h0bbel), his blog vNinja.net and I have also listened to a few of his podcasts, vSoup, which he does regularly with co-presenters Ed Czerwin (@eczerwin) and Chris Dearden (@ChrisDearden).

#FeedForward

We all enjoy going to our local VMUG meetings and hearing about new cool products but even more we love hearing from our follow peers. The community sessions are one of the strongest things of the VMware User Group.

I remember hearing about how people built their own self service portal years in advance of vCloud Director and vCAC and listening to real life experiences.

What we need is more community sessions. A lot of guys have so much to share, but not all feel confident about it. This if what #FeedForward is all about. Instead of getting Feedback (after the presentations is done, and it is possible the only time you will present it) There is much more value into getting Feedback in advance hence #FeedForward. This will make sure your presentations will improve and that you will enjoy presenting your own cool story.

Mike Laverick is the man behind the program. A new landing page was just created. http://www.vmug.com/feedforward

 People can express the intention to either:

  • Becoming a Mentor and reviewing presentations for VMUG events
  • Sharing a presentation at a VMUG event
  • Serving on a Committee to promote FeedForward

If you want to help mentor your fellow VMUG’ers og present your self please sign up on the website.

I am personally a #FeedForward Mentor and have already helped a few guys before their first presentation.
