Where do I go for EMC & Open source scripts/tools/etc?

December 10th, 2014 No comments

As a former application developer (sort of) and an administrator/architect before coming to EMC, I constantly wrote code, scripts, and anything I could do to make my life easier.  I always kept my stash of code, but I never had all the pieces I needed, and would go looking for code samples, or prewritten code, when I needed it.

I remember being given some tasks 20 years ago, where I had to automate some authentication processes on a Slackware Linux system for my remote users.  We didn’t really have the SSO capabilities that we have today, and to make this happen, the process was comprised of custom code/scripts, cron jobs, and a waiting period until everything caught up.   I’d grab this piece of code for the shell BBS I was running, along with some code to handle the authentication updates, handling the bank of screaming 14.4K modems for RAS, and so on.  When I needed code, I’d have to look at a multitude of different places for code/samples/tools/etc.

vSphere 5.5 & the Isilon NAS VAAI Plugin – Part 2 – v1.2

December 4th, 2014 1 comment

If you have vSphere 5.0/5.1 and have waited to upgrade to 5.5, at least in part because you have some Isilon NFS datastores, you wait is over.

In case you missed it, an updated vSphere VAAI plugin for use with Isilon storage (NFS) was released recently.

I downloaded the updated plugin from EMC’s Support Site. Looking at the release notes, OneFS 7.1.0 is the minimum version of OneFS supported.

The installation process is the same as a previous post (Configuring the EMC Isilon NAS VAAI Plugin for vSphere 5.0/5.1).

In my lab, tried it out on a OneFS 7.2.0 virtual cluster… After a host reboot, I see VAAI is supported.

isilon-nfs-vaai-1.2I haven’t tried the plugin with vSphere 5.0 or 5.1.

I know that EMC and VMware worked together for a while to validate this package, and I’m glad to see it has been released.

ScaleIO 1.30 – VMware vSphere Installation – Part II – SVM Setup

October 24th, 2014 No comments

Keep in mind that, other than the new features added in ScaleIO 1.30, it still operates in the same fashion on vSphere.  Each host still has a ScaleIO VM (SVM) that leverages vmdks, residing on local datastores, as well as can run one or more services including the Metadata Manager (MDM), ScaleIO Data Server (SDS), & ScaleIO Data Client (SDC), & iSCSI Target.

Where ScaleIO 1.30 differs from 1.2x, is the manner in which it is installed, and managed, especially when it comes to creating additional volumes, protection domains, nodes, and the like.  With ScaleIO 1.30, a vSphere Web Client plugin is added to handle all of these functions.  In Part I, I covered setting up the ScaleIO Gateway and registering it with the VMware vSphere Web Client.

Loading the SVM (OVA) Template
Before the process can begin from the Web Client plugin, the ScaleIO OVA has to be uploaded to a vSphere datastore.  This can be done manually, or can be accomplished using a provided PowerCLI script.  Using the provided script, the OVA is uploaded to one or more datastores, and converted to a Template.  It is important to note that the script will upload the OVA to multiple datastores.  This can be very expedient when deploying SVM nodes on multiple hosts.  In my test environment, I loaded one OVA on each host, for all 3 hosts in my lab.

ScaleIO 1.30 – VMware vSphere Installation – Part I – Gateway Setup

September 25th, 2014 No comments

Since ScaleIO 1.30 has been released, I can now publicly talk about how to install it in a vSphere environment.

To learn what has changed, I’ll start by covering the process of installing 1.2x first.

With 1.2x, a ScaleIO VM (SVM) is loaded on each ESXi host, and configured in the same fashion as deploying ScaleIO on Windows, Linux, or alternate Hypervisor configurations, with one exception.  Where the installation differs from all other ScaleIO installations, is that an iSCSI target service is created on each SVM, and each host then connects to the ScaleIO presented storage over iSCSI.  This has not changed yet in 1.30, but the installation still differs.

In ScaleIO 1.2x, a menu driven install script is used to stand up an initial environment, but additional nodes are added manually after installing all the components.  The 1.2x install script does not easily accommodate the addition of nodes.  Those functions are performed after the binaries have been installed on any new ScaleIO nodes.
