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 Incentivized
Large scale data storage: Red Hat Ceph Storage is designed to be highly scalable and can handle large amounts of data. It's well suited for organizations that need to store and manage large amounts of data, such as backups, images, videos, and other types of multimedia content.Cloud-based deployments: Red Hat Ceph Storage can provide object storage services for cloud-based applications such as SaaS and PaaS offerings. It is well suited for organizations that are looking to build their own cloud storage infrastructure or to use it as a storage backend for their cloud-based applications.High-performance computing: Red Hat Ceph Storage can be used to provide storage for high-performance computing (HPC) applications, such as scientific simulations and other types of compute-intensive workloads. It's well suited for organizations that need to store Incentivized
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 ManagerReliability and Availability -- This is the platform that gets used for the most demanding environments, even when FICON attachment isn't requiredContinued enhancement -- IBM continues to put resources into the DS8k and the platform has advanced with the technology from z and powerMainframe synergy -- Poughkeepsie communicates and works very closely with the DS8k developersIncentivized
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.Incentivized
The DS8000 family still lacks deduplication and compression algorithms.For best results on replication enablement, optional Copy Services Manager is suggested.Incentivized
GUI based mainetenence should be developedUnable to detect storage latenciesVM to disk mapping should be visible so as to save some critical applications data in case of HDD failuresIncentivized
DS8882F provides CKD storage in a manageable footprint. Its advantage over FlashSystem is its interoperability with IBM Z Systems Incentivized
MongoDB offers better search ability compared to Red Hat Ceph Storage but it’s more optimized for large number of object while Red Hat Ceph Storage is preferred if you need to store binary data or large individual objects. To get acceptable search functionality you really need to compile Red Hat Ceph Storage with another database where the search metadata related to Red Hat Ceph Storage objects are stored.Incentivized
I do not know the cost. If it prevents future system wide outages, it will be a great ROI for our company.Incentivized
Ceph allows my customer to scale out very fast.Ceph allows distributing storage objects through multiple server rooms.Ceph is fault-taulerant, meaning the customer can lose a server room and would still be able to access the storage.Incentivized
