NetApp's ONTAP Data Management Software is a storage and data management and protection solution. ONTAP 9 allows users to build an intelligent hybrid cloud that is the foundation of a NetApp Data Fabric that spans flash, disk, and cloud. Flexibly deploy storage on a choice of architectures—hardware storage systems, software-defined storage (SDS), and the cloud—while unifying data management across all of them.
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
NetApp ONTAP Data Management is a must platform to most businesses around the globe since the tool generates various capabilities for the user to easily and very securely manage all the project data through the cloud services using the platform capabilities. The data analytics are generated in real-time and easy visualization of different data which the tool helps the user import across other platforms.
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.
Not necessarily a dislike of OnCommand per se but I do dislike that you have to still use different flavors of this tool to get a holistic view of every aspect of your NetApp - System Manager, Performance Manager, Unified Manager etc
The initial process to connect to a filer probably could do with a little more friendly documentation as the format for filer name (or IP) and whether and SNMP string is required etc is not clear.
The ability for more complete search capability within the logs (so therefore not having to extract them to work with them) would be an advantage for the timely resolution of faults.
Support is great. Our account managers and system engineers regularly contact us and check in on us. Provide free training on various topics. Our team is readily available to answer any questions. Support tickets are generated automatically if anything goes wrong such as a disk going bad and a new one is sent out immediately. Very happy with support.
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
I have not been able to use similar platform though in service delivery and functionality capacity this is the most effective tool in our company. The entire organization data and workloads are always under secure environment when managed by this great platform. It has enabled us to meet our objectives and speed up operations across in all departments. Data in both cloud and on premise is automatically connected to provide multiple services and bring efficiency.
