Likelihood to Recommend Well suited for mainframe CKD based applications. There is unmatched synergy with IBM zSeries when compared to the competition, for example zHPF, SUPERPAV, zHyperLink, cache management and replication technologies. For distributed, the fact that Copy Services Manager comes with the box is a great move on IBMs part to provide replication capability no matter what the applicaiton. I think the DS8k is less suited for smaller distributed environments. I think product overlap with V9000 in this case
Read full review I would highly recommend using Nutanix HCI for any of your infrastructure needs. I would highly suggest saving money and using the free included AHV hypervisor. The performance is incredible, and the data reduction capabilities are on par with vSAN. I would only recommend using ESXi with Nutanix AOS if AHV does not yet support some one-off configurations or if you still want to use horizon while the frame is still growing.
Read full review Pros Remote Copy -- The DS8k has decades of excellent code built to handle the most demanding environments for mainframe or open systems and can be combined with automation solutions like GDPS or Copy Services Manager Reliability and Availability -- This is the platform that gets used for the most demanding environments, even when FICON attachment isn't required Continued enhancement -- IBM continues to put resources into the DS8k and the platform has advanced with the technology from z and power Mainframe synergy -- Poughkeepsie communicates and works very closely with the DS8k developers Read full review 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! Read full review Cons The DS8000 family still lacks deduplication and compression algorithms. For best results on replication enablement, optional Copy Services Manager is suggested. Read full review Can be priced high at times. 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. Read full review Likelihood to Renew 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.
Read full review Usability The learning curve on it is very low and easy to use. It is very user friendly and easy to understand.
Read full review Reliability and Availability So far no issue on availability during no issue on network or power outage
Read full review Performance Nutanix AOS performance is light years ahead of HPE. We were nervous about using Nutanix AHV but it has been a vast improvement and saves on cost. Applications has been much improved and end users have commented. It has also freed up time for our Network Administrators and made their lives easier.
Read full review Support Rating Modernizing with HCI, which creates private cloud-like data centers, is, for many organizations, the first step in their digital transformation. Companies that have kept their eye on the long game and made decisions based on a fully-developed ROI analysis have found themselves uniquely positioned to make the critical operational changes the COVID-19 situation has demanded.

Read full review Implementation Rating 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.
Read full review Alternatives Considered DS8882F provides CKD storage in a manageable footprint. Its advantage over FlashSystem is its interoperability with IBM Z Systems
Read full review We've decided to go for both VxRail and Nutanix AOS to make sure we can get the best deals from both sides. I appreciate this may not be a path most companies can go down, but always good to have a bit of healthy competition between vendors to ensure you're getting the best pricing from both sides!
Read full review Scalability We have scaled our products over the years and continue to do so very easily.
Read full review Return on Investment I do not know the cost. If it prevents future system wide outages, it will be a great ROI for our company. Read full review We save money with an all-inclusive pricing model and cut out of extra pieces we no longer need The management of this product is minimal and save time and resources. We found that the N+1 portion is working well but not identified well. Read full review ScreenShots
