One of the major advantages we have seen with VVols is making a virtual disk a first class citizen on the array. We can restore, copy, replicate them (and their VMs) as storage objects were meant to be restored, copied, replicated etc.
Though one thing about virtual disks is that by default–they are not first class citizens in vSphere, VVols or otherwise. To create one, it has to be associated with a VM.
To retrieve one in PowerCLI (for example) get-harddisk requires a datastore or a VM to return a result:
The first of two long anticipated VMware Site Recovery Manager updates is finally here! (the second being discussed here). A SRM appliance!
Since the dawn of time SRM was a Windows-based application. Requiring you to install, configure, and maintain Windows server and then install SRM on it. Certainly adding to the complexity of getting SRM up and running. Everything else VMware offers is an appliance why not this?
Well a couple reasons–but a primary one though is the ecosystem. SRM, unlike many other offerings relies vary heavily on ecosystem partner’s plugins. With essentially the single exception of vSphere Replication, SRM is useless without those vendor plugins, called Storage Replication Adapters (SRAs).
Today Pure Storage officially released support of NVMe-oF support on the FlashArray. This is another important step forward in the FlashArrays progress with NVMe. Prior to this, we have made a few incremental, but important improvements in the product to add full end-to-end support of NVMe:
Converting our NVRAM devices to use NVMe
Moving off of SSDs and adding custom NVMe-based flash modules in the FlashArray//X chassis
Adding support for drive shelves that are connected via NVMe-oF
Officially release NVMe-oF support for front-end workloads.
This has been a multi-step process that we spent a great deal of effort to make sure we were fully taking advantage of what NVMe in general has to offer.
This post is somewhat specific to Pure Storage–the cmdlets of course are universal, but behaviors may not correlate to your storage array. So if you are using VVols on a non-Pure array, certainly consult your vendor.
Furthermore, this is certainly specific to PowerCLI when it comes to the commands. With that being said, the fundamentals on how this works with Pure is common for all orchestration tools, so you should be able to use this information for other tools. Though of course the cmds/syntax will be different.
Hello there! The FlashArray and FlashBlade products from Pure have always had a REST API service built in–this REST service allows you to manage, provision, and pull raw statistics from the array.
But there are two pieces missing:
You need to iterate through each array if you want to intelligently place a volume on it (or find a volume or whatever)
They only offer raw statistics–you need to do some crunching possibly to get what you want. Create projections and forecast, find how busy an array is, etc.
Luckily this is what Pure1 does for you. Every customer has access to our Pure1 web tool. This is something we host, all of your dial-home information gets fed into it. We use that information to figure out how “busy” an array is, when it will fill up from a capacity or performance perspective and much more. We now offer a REST API for Pure1 as well, so you can do some one-stop shopping for the information you need, that the arrays cannot natively provide.
