EMCWorld 2013: IOPS calculation for your FAST Pool

Posted on May 9, 2013 by Menno de Liège

Inside this post I will provide a calculation example for calculating the required spindles in combination with a known skew. No capacity will be addressed in this post, where I will base it purely on IOPS / throughput and apply it to a mixed FAST VP pool. Continue reading →

EMCWorld 2013: Without skew, no flash

Posted on May 9, 2013 by Menno de Liège

When you have a VNX in your environment, you want to use the most innovative features and disks that are available. People tend to say “I want flash”, but you can never put your entire environment on flash, meaning you need to know what needs to be on flash. Besides this, you need to know the amount of flash that needs to be available and whether to place it in your FAST VP pool or FASTCache. Continue reading →

EMCWorld 2013: Introducing new Cisco MDS stuff

Posted on May 6, 2013 by Menno de Liège

Due to different nice things in Vegas combined with EMC Elect stuff, I am not able to attend as much as sessions that I had in my mind, but today I attended the session “Cisco/EMC Multiprotocol Fibre Channel SAN’s for performance, availability & architectural flexibility. Inside this blogpost I will address the stuff presented by Cisco combined with my view on these items. Continue reading →

Welcome @ EMC World 2013

Posted on May 4, 2013 by Menno de Liège

Today I arrived at Las Vegas for attending the annual EMC World. Together with my collegues and EMC Elect co-members @50mu and @JonKlaus we’ll meet up with other EMC Elect members to socialize, share experience and share knowledge. Besides enjoying Las Vegas and all the other stuff in and out of the event ,I will attend different sessions on which I will base some technical blogs for the next week.

When will we trespass with VNX ALUA?

Posted on May 1, 2013 by Menno de Liège

In the early days a Clariion was a real active/passive array, meaning that one Storage Processor owns a LUN and the only way to reach the LUN is by using a path via de owning SP. When all paths to the owning SP fail, you would need a trespass. Then there was ALUA (Asymmetric Logical Unit Assignment) on the Clariion and VNX, which makes it able for us to access the LUN via the non owning SP, using the CMI (Clariion Messaging Interface). But what about the need for a trespass? Continue reading →

Avamar & dedicated replication vlan

Posted on March 14, 2013 by Menno de Liège

When using an Avamar Gen4 grid, you can choose to use a dedicated bond for the replication traffic or you can choose to share this replication traffic with your backup connections. Inside this post, I will explain how the replication traffic flows and the configuration requirements of this traffic flow combined with the choices you can make. Continue reading →

VMware Fusion & Host Only Private Network

Posted on March 11, 2013 by Menno de Liège

I am using VMWare Fusion 4 on my MAC OS and I wanted to add a new VM which should only be available from my Macbook by using a Host Only Private Network. Besides this, I wanted to use it without any NAT rules, because inside this host there was some stuff being emulated which I needed to connect to (Cisco UCS Emulator). I was not able to get it to work using the GUI, so I managed to configure it from the command line. Continue reading →

Cisco MDS Inter VSAN Routing & Scripting

Posted on March 4, 2013 by Menno de Liège

When using a Cisco MDS environment with the Inter VSAN feature on a 9222i for example, it can take a lot of work to complete the zoning configuration. The most easy way is to use the GUI based IVR wizard, but you do not want to do this for every zone to create. Inside this post I will address the requirements for doing it easier, besides looking at the way to perfom this using the command line. In the end I will provide a powershell script that will make stuff a little but faster for you. Continue reading →
