Smaller sites that would benefit from a cluster of 2-5 nodes. Not saying that it can't scale above that, but I find HyperFlex a great solution for those sites. A simple 3-node edge cluster can provide a huge amount of resources and redundancy. It's also really easy to scale the environment to meet growth requirements.
I only know what I know...which is my IT world. Having two datacenters that were physical servers attached to a SAN that "attempted" to replicate and then migrating. For a SMB small IT shop that happens to have two datacenters already in place...this has been ideal. I can have a generalist maintain the system and we have a private cloud for DR with hardly any effort...the biggest gain by far!
UCS manager in HX is truly helping us in doing one touch firmware upgrades. Scaling of HX cluster (in few minutes) is too seamlessly due to service profiles.
HX does not hold you back by creating a single data store unlike other HCI products. With HX, you can create multiple data stores and allocate those to desired services. This help logically separate the install base on HX and removes confusion for the admins too.
We run high IOPs workload on HX, and we never felt latency issues due to the Cisco backbone (as you get FI as a TOR switch and options to choose 10G or 40G speeds).
With HX you truly enjoy a single window support from Cisco including for the top of the rack switch (FI in HX case). In other HCI infra, you certainly have to bank on to network switch vendor for support and bring HCI and switch vendor at one pane for troubleshooting latency related issues.
While we increased our footprint on HX, we didn't added additional administrators to support the landscape. This was possible because of the simplicity in managing HX clusters.
With HX we had setup stretched cluster between two near site data centres. This is a unique proposition in HX (we have 2 nodes in each data centre) and data centre failover works absolutely seamless.
Deduplication and Compression - SimpliVity keeps the space consumption to a minimum. We currently have 60 servers running virtually and we still have room to grow. This really helps with the backups as we can have longer retention.
Backups - Ability to keep backups for longer and to create multiple backup policies for a VM is a breeze. You can have a backup policy for each datastore as well as a separate backup policy for the same VM.
Creating Datastores is very easy. No more messing around with LUNS and iSCSI. Just go to the SimpliVity tab and select create datastore and it's done. You can also increase the datastore on the fly as well as have a datastore bigger than 2TB.
File level recovery is included as well. The whole backup process in SimpliVity can help you do away with other software.
there is the problem with starting cluster where there are not outside DNS and NTP services so we need to workaround this with additional storage or hosting it on the local storage.. many clusters has internal DNS/NTP services not available from outside and they need to be hosted on the HX
there is not RBAC or user mgmt on the CVMs so it is difficult to not add full permission for the people responsible for just shutdown and power on the cluster
native snapshots support with ibm backup products
running from not the only last snapshot in all use cases
More documentation is available now than when the product initially came out (which was an issue early on). Because it only supports UCS hardware, I think it does help with support issues. Nutanix has to support much more hardware. At the same time, you're dealing with the Cisco TAC, which can be mixed at times.
Support is very good. With proactive support, you are supported by an engineer in North America who answers the phone and immediately begins assisting with your issue. The folks I have dealt with in the last several years have been very skilled and it is rare to have a ticket open for more than a day or two. Issues affecting production are dealt with appropriately and are escalated within the support organization.
HyperFlex is built on top of Cisco UCS infrastructure, which allows us to manage other non-HX servers attached to the same UCS environment. This allows us to tie everything together via Intersight and see all of the servers in our data centers. Other platforms don't really have a comparable offering.
The simplified management makes it easier to operate and prevents mistakes.
Guided installation using the installer VM means you don't have to configure every component by hand. Improves deployment speed and lowers the risk of configuration issues.
Performance increase of 40-90% compared to our previous compute/storage cluster.
HPE SimpliVity provided us with the ability to replace our existing infrastructure with a solution that provided better backup and recovery, and an off-site DR solution, at a lower price point than other solutions.
