VMware workloads, the database, and Oracle Solaris are hosted on AFF, which means that our primary priority workloads are on AFF and that the secondary ones are on FAS. "It is a stable solution." "This solution helps accelerate demanding enterprise applications. Dell is right there in the mix as far as providing the best price point as well as meeting the performance requirements that we have." "The support is very good." "There is no complicated configuration for queries and calls. It's very competitive against those of all the others that I looked at in the marketplace, such as Hitachi, IBM, HP, and Pure. Building hardware, especially in a big VMware environment, is a big issue for my organization." "The compression is excellent." "Dell EMC PowerStore is scalable." "Pricing is very good. You reduce almost 80% from the hardware and work directly from PowerStore. So, it is cost-effective, which is very important and has been massive for us. For example, in a big environment with 10 to 30 ESXs, you can take everything and put that into PowerStore. It supports compression and duplication leads." "It provides a big benefit when upgrading a new VMware environment. This is the most powerful feature of this series. What’s also cool here is that deduplication on Nimble occurs at the Pool level rather than volume level."Migrations are very easy and fast." "The most valuable feature of Dell PowerStore is the all-NVMe flash storage. This ensures that the latency is kept consistently low whilst performing data migrations. Nimble Connection Manager (mentioned above as a critical component) is used to abstract the IO away from the iSCSI or FC persona of each array – instead it virtualises the connections to the group itself and is able to re-map and direct I/O to each array on the fly without the need for hopping between systems. In this example, there could be many applications (VMs, physical servers, containers etc) all connected and having it’s IO served by the array group. However, this blog is about migrating my workloads from my old array to new with minimal downtime! So let’s do that 🙂 Non-Disruptive Data Migration Between Pools It’s possible to run my environment within a scale-out environment if required (the maximum we support is up to 4 arrays in a group). Therefore, you can jump into your current Nimble array UI, head to the “ Hardware” tab, and click Actions->Add Array To Group. Once you’ve racked, cabled and powered on your new system, the array will start sending broadcast packets onto your network in order to be discovered. If you’ve done all of the above, then we’re ready to get going. This is a critical part, and should not be overlooked. Nimble Connection Manager should also be installed on your Windows, VMware or Linux servers.

Both systems need to run the same NimbleOS software release.Both old and new platforms are residing on the same data network – ie iSCSI or Fibre Channel.Let’s Scale-Out!īefore you start, it’s important to ensure: Most importantly, I want to do this as easy as possible, with the most minimal amount of application disruption! Typically, storage array data migrations are the bugbear of the enterprise IT industry.Īnd this is exactly what we can use Nimble Scale-Out technology to do for us, with minimal app disruption or downtime.
Perhaps I want to migrate my environments to All Flash, or perhaps I want to repurpose my older Nimble array to Disaster Recovery, or even for another project elsewhere. Whilst this array has done a fantastic job, I now wish to replace my older Nimble array with a newer Nimble platform. Array UI showing vnmbl-group with a single array
