Force the Invoke-RestMethod PowerShell cmdlet to use TLS 1.2

I wrote about some security changes in the FlashArray operating environment (called Purity) version 4.7 a month or so back. This was concerning the deprecation of SSL and TLS version 1.0, forcing all (management) connections to the FlashArray to use TLS 1.1 or 1.2 (read this here).

Our PowerShell SDK was enhanced so it would use the appropriate security connection type so users of that do not need to worry as long as they upgrade our SDK. But what about the few remaining functions that people might use that the PowerShell SDK doesn’t cover? As there are a few REST calls that are not built into the SDK (yet).  Continue reading Force the Invoke-RestMethod PowerShell cmdlet to use TLS 1.2

Introducing FlashArray Purity Release 4.6

It has been awhile since I have done a solely Purity operating environment post and with the recent release of our Purity 4.6 operating environment I thought it was a good opportunity to do one. I will overview some new features and changes, some big some small.

4.6 has been in Directed Availability (DA) for some time, so many of you might already have this, but I decided to wait until it was closer to GA (this is imminent) to post. Not a gigantic release, but I think there is some cool stuff in it regardless.

Here is a brief listing of some of the new stuff:

NEW FEATURES

  • VLAN tagging Introduces support for VLAN tagging for iSCSI connections to the FlashArray. VLAN tagging allows multiple VLAN interfaces to be configured on physical iSCSI ports.
  • Replication network bandwidth throttling Introduces the ability to set a maximum network bandwidth utilization for replication between two connected arrays. Allows configuration of a default maximum bandwidth and/or a time window during which a different maximum bandwidth is enforced.
  • Deduplication-preserving replication Introduces the ability for Purity to preserve inline deduplication savings when transferring replication data to a target array, to reduce the network bandwidth utilization.
  • Protection group copy Introduces the ability to copy protection groups, including their member hosts, volumes, and snapshots. Protection group copy is supported in the CLI and REST API.
  • The Pure Storage SMI-S Provider Release 1.0.0 of the Pure Storage SMI-S provider is embedded in Purity 4.6.0 release. SMI-S enables both hardware and software interoperability between different vendors’ enterprise storage products and allows vendors to develop to a single standard interface. For more information, please see the SMIS-S release notes.
  • Improved readability of graphs in the Purity GUI In the GUI Dashboard and Analysis tabs, changes the color of the write graph to orange to distinguish it from the blue read graph.
  • CLI Changes This is mostly to cover the new features above
  • REST API version 1.5 Some new REST calls for new features and general enhancements and fixes for our REST API service.

FlashArray //m and VMware Integration–What do you need to know?

Last week Pure Storage introduced the latest iteration in the FlashArray product line: the FlashArray //m. While Pure Storage has traditionally focused on software innovation from a technical standpoint, we decided that the only way to stay ahead of (and lead) the curve was to innovate in the hardware realm as well. Therefore, for the last few years, development on producing a hardware platform that could keep up with compute and storage speed and capacity leaps has been at full tilt. This produced the brand new FlashArray //m.

FlashArray XCOPY Data Reduction Reporting Enhancement

Recently the Purity Operating Environment 4.1.1 release  came out with quite a few enhancements. Many of these were for replication, certain new GUI features and the new vSphere Web Client Plugin is included. What I wanted to talk about here is a space reporting enhancement that was made concerning VAAI XCOPY (Full Copy). First some history…

First off a quick refresher on XCOPY. XCOPY is a VAAI feature that provides for offloading virtual disk copying/migration inside of one array. So operations like Storage vMotion, Cloning or Deploy from Template. Telling an array to move something from location A to location B is much faster than having ESXi issue tons of reads and writes over the SAN and it also therefore reduces CPU overhead on the ESXi host and reduces traffic on the SAN. Faster cloning/migration and less overhead–yay! This lets ESXi focus on what it does best: manage and run virtual machines while letting the array do what it does best: manage and move around data.

Pure Storage Web Client Plugin version 1.1.13

I have done a few posts on here that involve the Pure Storage Plugin for the vSphere Web Client (here and here) since I joined. Well here is another. We just released a new version of the Web Client Plugin (I am going to refer to it as WCP for the rest of this post because I am a lazy typist). We bundle the WCP into Purity and therefore the WCP is installed, updated and uninstalled from our GUI/CLI to vCenter (yes we do also offer a mechanism to update it outside of upgrading Purity itself). Our latest release of Purity, 4.0.12, includes WCP version 1.1.13–while there is no new functionality there are two important fixes.

Using VMware Log Insight with the Pure Storage FlashArray

I’ve done a few VMware Log Insight posts in the past year but I have yet to do one for Pure Storage. Log Insight is a product that I really love and VMware has been updating it like crazy since its initial release. Just recently they announced the 2.0 version of Log Insight (more info here). Besides just being functionally useful it is VERY easy to use–from kicking off the deployment (it is an OVA) to first use it takes about ten minutes maximum.

Purity 4.0 Release: New hardware models, replication and more!

Ah my first official post during my tenure at Pure and it couldn’t have happened at a better time! Just in time for the Purity 4.0 release which we just announced today. While there are plenty of under-the-cover enhancements I am going to focus on the two biggest parts of the release: new hardware and replication. There are other features such as  for example hardware security token locking but I am not going to go into those in this post. So first let’s talk about the advancement in hardware!
