Today the long-awaited update to Virtual Storage Integrator for the vSphere Web Client as been released! Six months or so ago EMC released the first iteration of the VSI Web Client (version 6.0) that supported provisioning of storage but only for environments enabled with ViPR. The latest release (version 6.1) now adds support for direct provisioning of storage from a VMAX or VNX array.

My colleague Jonas Rosland (@virtualswede) has been doing some great work with Splunk recently (check out a post from his blog here) and it got me to want to get my own hands a little dirty. So far I’ve only scratched the surface on what can be done with Splunk but I decided to put a post together on some basics. For this post I am going to talk about Symmetrix VMAX logs and how to get those into Splunk.
Recently I had a partner/customer who was migrating a lot of SAP data from one VMAX to another VMAX and they ran into an issue they weren’t sure how to solve, well at least what the best way to solve it was. This person had a ton of data on the VMAX and more than a few TimeFinder/VP Snap point-in-time copies of each SAP volume that they used for testing/recovery or backup.
For those of you unfamiliar with VP Snap it is a rather new (introduced with 5876) method of local replication on the VMAX that leverages the space-efficiency benefits of TimeFinder/Snap but also offers the flexibility of configuration provided by TimeFinder/Clone.

Quick overview, the SRDF Storage Replication Adapter for VMware SRM TechBook is an in-depth implementation guide focused on how to install, configure and manager SRDF with VMware’s vCenter Site Recovery Manager product. Overview of SRDF, the involved tools and how to perform test recovery, migrations and disaster recovery failovers.
My last hurrah with this TechBook! Since I have moved on to a new (and exciting!) role within the Open Innovation Lab in the EMC Office of the CTO it is time for me to pass on the torch of the SRM TechBook.
Anyways you can find the updated TechBook here:

Late last week I posted a summary blog on the latest SRDF Storage Replication Adapter for VMware Site Recovery Manager here:
I detailed out the new features etc for the 5.5 release and briefly mentioned the latest release of the Virtual Storage Integrator Symmetrix SRA Utilities that helps users configure the SRDF SRA. On 10/25, we posted the latest release of the SRA Utilities, version 5.6.
Version 5.6 of the SRA Utilities have been enhanced in tandem with the SRDF SRA to support the new features that the SRA has to offer. Most of these enhancements relate to the masking control functionality that is newly supported by the SRA.

As some of you are aware, myself and my colleague Drew Tonnesen (@drewtonnesen) write and update an EMC document called Using EMC Symmetrix Storage in VMware vSphere Environments. This document is what we call a “TechBook”. Essentially a very detailed explanation of the best practices of using VMware with Symmetrix storage as well as overviews of integration points. If you are using Symmetrix and VMware this is a document you should use/know.

Hey all! So as many of you have heard we (EMC) has released the latest version of the Virtual Storage Integrator today (September 16th 2013). There are plenty of blogs/posts that go into all of the details of the new release so I will not regurgitate all of that here. But for those of you who have not seen these posts check them out at these links:

A common recommendation from storage vendors is to change the default IOPS setting for VMwares’ Native Multi-Pathing (NMP) Path Selection Policy (PSP) Round Robin. The IOPS setting controls how many I/Os are sent down a single logical path before switching to the next path. By default this number is 1,000 I/Os. The VMAX recommendation is to set this to 1. The purpose of this blog post is not to debate the setting, but to help those who want to use it. Regardless, I have seen many customers benefit from this recommendation. Once they see a benefit they want to know–can I make this setting a default?

This is a topic that I get asked about a lot and a recent internal email thread prompted me to write a post about it. On a Symmetrix array if you want a volume larger than 240 GB you need to create a metavolume. When creating a metavolume you have two configuration choices; concatenated or striped. There are many benefits to striped over concatenated (all of them performance-related) but one disadvantage. Due to their nature striped metavolumes are harder to expand. Until a few years ago thin striped metas couldn’t even be expanded online. So the decision was easy–do you think you will need to expand or not. In Enginuity 5875 and Solutions Enabler online expansion of striped metavolumes was allowed.
As you may or may not be aware, I am the sole author of the SRDF Storage Replication Adapter for VMware Site Recovery Manager Techbook. The Techbook for those of you who haven’t used it or aren’t aware of EMC Techbooks is a implementation guide for SRDF with SRM. Best practices, how-to, hints, etc.
