Nutanix in San Jose, California offers their software-defined Enterprise Cloud as a hyper-converged infrastructure solution. The Nutanix Cloud Infrastructure solution combines the Nutanix Acropolis virtualization solution, Nutanix AHV hypervisor (though Acropolis works with other hypervisors), Prism cluster manager, Nutanix Calm and Nutanix Flow server management, and is available on the Nutanix NX series of server hardware appliances, as well as third-party OEM appliances.
Top choice for IBMi integration. In general, it's a very good solution for quite a lot of customers. If you need a 3 site replication solution (HA + DR) maybe it's not the best solution, unless you use SVC. FlashCore Modules have very powerful compression rate, while mantaining good performance: high IOPS rate and really low latency
For an organization that requires top-notch performance HCI, Nutanix is the best. You may start with 3 nodes and expand the cluster as required. The management through Nutanix Prism Central and Element was so easy that even a Junior Engineer was able to handle it. The Nutanix platform is not suitable for organizations with a small budget and fewer requirements for high-performance infrastructure, as the Nutanix solution itself is suited for enterprises.
One-click upgrades; whether it's hypervisor, firmware, disk or other updates. This feature has drastically decreased complexity and administration time.
Data Locality. Not all hyperconverged technology is created equal. When I first purchased Nutanix they were the only vendor (and as far as I know, still are) that made sure the storage a VM used was on the same host that VM was running on. Given a normal operating state, the [storage] network is literally only used for replication data.
They got rid of traditional RAID. Nutanix uses software to determine where a VM's storage should be written and replicated to. This dramatically decreases I/O when changing the number of nodes in a cluster, be it on purpose or during a failure scenario. Ex. adding a new node: If one uses RAID arrays then enough space has to be set aside to create a new array that includes the new node, then all the information has to be copied over, and the old array destroyed. RAID arrays do not grow and shrink gracefully so Nutanix has designed a better solution.
The Nutanix management interface was built on HTML5. No more flash headaches!
Definitely we need to be able to extend a volume that is part of a mirror pair or Policy-Based Replication(PBO) on the fly.
Expansion of mirrored volumes/volume groups should resynchronise only the changed data (Almost like making use of change-volumes) and not trigger a full resync.
Please allow us to select downloading drive microcode also from Fix Central directly onto the flashsystem like with updates.
The one downside I have working with Nutanix is the sales team. They seem to try to add in extra goodies to sales quotes or push for extras that you don't really need and you have to tell them to take them out. Don't be afraid to push back on them.
Need to analyze sizing with sales team to ensure right sizing.
As flash technology evolves rapidly, vendors should [adapt] to the changes and onboard them in their products. IBM is a bit slow in adopting advanced technology in [its] portfolio. Even though the current product is good, my decision is purely based on how the transformation of the product [is] being produced and supplied to [the] end-user.
AOS definitely make our dev/test virtual environment management much easier than before. And the consolidation the test/dev environment from Azure and Cisco UCS, we have less need to transfer large amount of data between different hardware platforms which was very big challenge. To expand the capacity is very easy to archive as well.
The integration into our SVC and the midrange systems are very well working. We do use cross site replication and global mirror which in turn is easy setup and the consistency groups are well maintained. The storage does global mirroring but also internal cross room replication as well. The integration of cloud object storage also helps in tiering the overall system.
It's not out of the box easy, but once you get the fundamentals the steep learning curve flattens out and the processes to get things done and how it works becomes very apparent. It's wrapping the slight change in workflow from prior VM management methods took time to unbox and apply the Nutanix Cloud Infrastructure way
Yes. The last really issues I've seen in the environments of my customers were back in the "Storwize" era of systems. Issues with code updates or sometimes rarely failing critical components. BUT: since every component is at least dual redundant even back in that day real outages were very rare. And today in the "FlashSystem Era" the systems are so reliable and available even during code updates there are no complaints. I think the 5 or 6 9s are completely achieved.
Latency and throughput have been excellent. The compression is done natively on the NVME modules so we do not see an impact there. the distributed parity does not seem to impact write speeds at all. We have found database performace has increased quite a bit over our old hybrid storage solution.
Having a single tier of performance makes it easy to set up SLAs for workloads.
The performance is nothing short of amazing. This is an HCI solution, and as any all-flash HCI solution is amazingly fast, Nutanix AOS fills local IO requests until its local IO is saturated before reaching out over the network. This lowers latency substantially compared to vSAN.
I would rate the overall support for IBM Storage FlashSystem with a 10. The response times have consistently been fast, and the support engineers always come prepared with relevant questions and practical solutions. They demonstrate a deep understanding of the product and our use case, which means issues are typically resolved quickly and without unnecessary back-and-forth. This level of support has been especially valuable for our SAP environment, where uptime and quick resolution are critical.
Our implementation team were great and worked with us and got the program up and running very easily. Every time we called post implementation we immediately talked to an Engineer, which is so unusual in dealing with companies. Everything they have promised they have full filled. I think their support is top notch.
Very good traning by experienced personnel. I attend instructor led sessions on IBM TechExchange and STUs before as well as IBM workshops for FlashSystems at IBM Böblingen which I helped to prepare and improve after piloting them. Absolutely nothing to complain about FlashSystem training in Germany or USA. So: all good here!
THe training is often selfpaced and easy to follow if you have worked previously with other storage products. The content is clear and contains all the information needed for an admin to learn. However the troubleshooting part is not always included and this is dependent on forums or other sources where the information is not accessible very easily.
I was amazed by the way IBM Flash storage provides a huge amount of storage within the limited footprint, it helped us to replace big fat storage arrays, which aided in the process of moving towards lower hardware, carbon, and energy consumption footprint. We can comfortably say that Flash helped us to host applications fast with a blazing speed and user transactions are quite quick.
IPv6 is needed for link local discovery. We do not have IPv6 configured on our network so the easiest way to get our nodes configured and discovered by foundation was to configure the IPv4 addressing within the node prior to trying to discover with foundation.
For the past six months, we have been utilizing this technology in our projects to manage a massive workload and produce swift business outcomes on a crucial production database. The IBM FlashSystem 7200, which offers high performance and compression, has so far been a great experience for us. The results and functionality of this product have delighted our consumers.
Nutanix integrates very well with Rubrik for backup and protection of the environment. Nutanix gave us simplicity and scalability compared to VMware and allowed us to extend our infrastructure into the cloud using EC2. One unified management pane for all our workloads, unlike VMWare.
I'm using cognos - especially cognos reports - as a part of IBMs Storage Intelligence software to manage datacenters and report storage and overall resource consumption to my customers. The software is reliable and - my customers who are using cognos in their businesses - say that they are very satisfied about the scalability of cognos. I can give it only an 8 rating because of the quite heavy resource footprint...
We find that return on investment is probably a better metric in most cases.
ROI analysis is more than an exercise. Companies must outline what their future looks like, even if it’s vastly different from what they’re used to and comfortable with.
As good as your financial analysis might be, displacing status quo infrastructure has a lot of emotions tied to it.
