That's a lot of data - from gifs and cat pictures to business and consumer transactional data. Disaggregate Ceph storage node and OSD node with NVMe-oF. A performance tier using Red Hat® Ceph Storage and NVMe SSDs can now be deployed in OpenStack, supporting the bandwidth, latency, and IOPs requirements of high-performance workloads and use cases such as distributed MySQL databases, Telco nDVR long-tail content retrieval, and financial services. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Format: 1. - sda and sdb are for testing Ceph in all three nodes - sdc and sdd are used by ZFS (Production) - sde is Proxmox disk - nvme is used for DB/WALL From GUI create first OSD and set 50 GB and it was created successfully.
