NMP Multipathing rules for the FlashArray are now default

As you might have noticed vSphere 6.5 Update 1 just came out (7/27/2017) and there are quite a few enhancements and fixes. I will be blogging about these in subsequent posts, but there is one that I wanted to specifically and immediately call out now.

Round Robin and IO Operations Limit of 1 is now default in ESXi for the Pure Storage FlashArray! This means that you no longer need to create a custom SATP rule when provisioning a new host or adding your first FlashArray into an existing environment.

Setting up iSCSI Port Binding with Standard vSwitches in the vSphere Web Client

Another how-to post on iSCSI. Essentially another “for the good of the order post” here. iSCSI is becoming increasingly common, so figured I would put a post together that covers the ins and outs of port binding with standard vSwitches.

For information on distributed switches (which I highly recommend using over standard vSwitches) check out this post here:

Setting up Software iSCSI Multipathing with Distributed vSwitches with the vSphere Web Client

So on to Standard vSwitches. Continue reading Setting up iSCSI Port Binding with Standard vSwitches in the vSphere Web Client

Setting up Software iSCSI Multipathing with Distributed vSwitches with the vSphere Web Client

Sorry the title is a bit of a mouthful.

I have written some posts on iSCSI in the past, around setup:

Setting up iSCSI with VMware ESXi and the FlashArray

Configuring iSCSI CHAP in VMware with the FlashArray

Another look at ESXi iSCSI Multipathing (or a Lack Thereof)

These have been on various parts, but primarily the setup around standard vSwitches, which generally, in at least in larger environments, is not the norm. Distributed vSwitches are. I have seen a few posts on doing this with the old C# client, but not the vSphere Web Client. Reference those posts here:

https://www.yelof.com/2011/07/13/dr-iscsi-or-how-i-learned-to-stop-worrying-and-love-virtual-distributed-switches-on-vsphere-v5/

So with the amount of questions I have received on it, it is probably worth putting pen to paper on it. Nothing profound here, basically a walkthrough.

This is of course assuming you are doing port binding. If you are not, then just the standard software iSCSI setup (as described in the above 1st post) is needed.

VMware and FlashArray PowerShell GUI tool v2.7

Quick post. I updated my PowerShell GUI tool I maintain for VMware and FlashArray management and added some new features. This time mainly around protection group management. Download it from my GitHub page here:

Rubrik and FlashArray Integration: Why it matters.

Just recently, Rubrik announced their integration with the FlashArray to help backup virtual machines and avoid the common performance penalty incurred during VMware snapshot consolidation. See their announcement here.

Queue Depth Limits and VVol Protocol Endpoints

I posted a few months back about ESXi queue depth limits and how it affects performance. Just recently, Pure Storage announced our upcoming support for vSphere Virtual Volumes. So, this begs the question, what changes with VVols when it comes to queuing? In a certain view, a lot. But conceptually, actually very little. Let’s dig into this a bit more.

Introducing vSphere Virtual Volumes on the FlashArray

This is a blog post I have been waiting to write for quite some time. I cannot even remember exactly how long ago I saw Satyam Vaghani present on this as a concept at VMworld. Back when the concept of what is now called a protocol endpoint (more on that later) was called an I/O Demultiplexer. A mouthful for sure. Finally it’s time! With pleasure, I’d like to introduce VVols on the FlashArray!

vSpeaking Podcast Guest Spot on vRealize Automation

Quick post. I had the pleasure and honor of being invited back to the vSpeaking Podcast hosted by Pete Flecha and John Nicholson to talk about vRealize Automation use cases. Alongside me was Aaron Patten of Solidfire to discuss the same topic.
