IBM Storage Ceph vs. Nutanix Cloud Infrastructure

It is absolutely, hands down the best storage solution for Open Stack. I would even argue it is the only solution if a company is operating at petabyte scale and need resiliency. The storage solution allows any organization to scale their environment using commodity hardware from top to bottom. It has a battle tested track record where it is even being used as the data storage back end for the Large Hadron Collider at Cern

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.

• Highly resilient, almost every time we attempted to destroy the cluster it was able to recover from a failure. It struggled to when the nodes where down to about 30%(3 replicas on 10 nodes)
• The cache tiering feature of Ceph is especially nice. We attached solid state disks and assigned them as the cache tier. Our sio benchmarks beat the our Netapp when we benchmarked it years ago (no traffic, clean disks) by a very wide margin.
• Ceph effectively allows the admin to control the entire stack from top to bottom instead of being tied to any one storage vendor. The cluster can be decentralized and replicated across data centers if necessary although we didn't try that feature ourselves, it gave us some ideas for a disaster recovery solution. We really liked the idea that since we control the hardware and the software, we have infinite upgradability with off the shelf parts which is exactly what it was built for.

• "Nutanix is an operating system playing inside an existing, rich IT ecosystem." Listen to Wendy M. Pfeiffer, CIO of Nutanix, as she shares game-changing results with the implementation of infrastructure-as-code.
• With one-click simplicity, Nutanix AOS streamlines IT operations and relieves budget pressures by integrating storage, networking, and compute services into a single solution managed by IT generalists. Start small and scale without limit to meet business demands.
• Deliver applications with the highest possible performance throughout the full lifecycle, not just day one. Provide reliable performance SLAs without worrying about workload changes or growth in application demands.

• Authorization on object level could be improved
• Helper libraries to access Red Hat Ceph Storage from various languages could be improved
• Ability to attach structured metadata to stored objects could be improved

• 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.

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.

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

We have not had any Nutanix availability issues over the years.

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.

Nutanix provide top tier support - their only rival in this field in my experience is Rubrik. Their sales and the aftersales team really put the effort in to make the initial install an easy process to complete and support we've required post that has been expertly handled. Their support's first point of contact is the equivalent of 3rd line at other vendors and they're always more than willing to explain concepts to help us better understand the issue/solution provided.

We requested more training than typical which was very in depth

A lot of online training courses, most of them are free.

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.

VSAN (Virtual SAN) and Ceph are both software-defined storage solutions, but they have some key differences in terms of their architecture and capabilities.VSAN is a software-defined storage solution that is built into the VMware vSphere hypervisor. It allows organizations to create a shared storage pool using locally attached storage on multiple ESXi hosts. VSAN is designed to be highly available, and it can automatically detect and recover from hardware failures.Ceph, on the other hand, is an open-source software-defined storage solution that can run on a variety of different hardware and virtualization platforms. It provides object, block, and file storage in a single platform, and is designed to be highly scalable and highly available. Ceph is also known for its ability to handle large amounts of data, and it can be integrated with a wide variety of different applications and services.In terms of functionality, VSAN is more suited for virtualized environments, as it is built into vSphere and it is designed to work well with vSphere's other features such as vMotion and DRS. Ceph on the other hand provides more flexibility as it can run on multiple platforms and it can handle more types of storage like object, block and file storage.I

vSAN on VXrail and a Cisco Flashstack was our two existing systems before bringing in a Nutanix cluster. The performance of Nutanix HCI was far better than vSAN's performance (hybrid vs. hybrid and AF vs. AF.) However, Pure does deliver on its claim of being the fastest storage possible, which is true. However, the flashstacks management and complex setup do not compare to the ease of using Nutanix HCI.

Can add on new cluster and join it to existing cluster

• Cost saving in terms of capex (you can reduce EMC & NetApp like dependency)
• One time setup & then easy provisioning of storage
• Requirement of competent engineers for maintenence

• Found an immediate reclamation of time. SAN's are a pain to manage and update - Nutanix made turned a couple hours of work into one click.
• They are a software company. Every Time they come out with an update I find my performance improving, or a new feature added. Soon I'll be able to give my developers controlled self-service capabilities. I originally bought hardware and it's evolving on me into a private cloud in a box.
