Quantum offers the ActiveScale cloud object storage system, acquired from Western Digital February 2020, designed to provide a highly durable, scale-out economic storage system. ActiveScale is a more recent model replacing the former Amplidata Object Storage product line that was acquired by Western Digital from HGST in 2015.
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
Enterprise grade organizations with B2B clientele would be served well by using this product. It alleviates the need for an on-premise storage solution by offering a cloud-based alternative. Smaller organizations with less data capacity needs would be better served with an in-house solution, unless they come out with more reasonable pricing down the road.
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.
It has been a fantastic solution, and now it is so highly integrated into our business, it would be difficult to imagine continuing to without it. It is part of our customer contracts as well, and it saves us from having to invest in the on-premise alternative to provide the required storage capacity.
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
What sets Amplidata apart is the cloud-based storage capability. We’ve realized cost savings due to the fact that we are no longer housing the data on premise, and clients rest assured that they have greater visibility into their data.
Amplidata has enabled us to replace our on-premise data storage for many of our larger clients, thus reducing the cost to deploy and house this ourselves
Clients feel confident in storing their sensitive data with us knowing that they have full management and visibility at their fingertips
The ability to quickly scale allows us to meet the needs of clients of all sizes
