Ceph is described as 'Distributed object store and file system designed to provide excellent performance, reliability and scalability' and is an app in the os & utilities category. There are more than 25 alternatives to Ceph for a variety of platforms, including Linux, Web-based, Self-Hosted, Mac and Windows apps. The best Ceph alternative is MinIO, which is both free and Open Source. Other great apps like Ceph are Vultr, Garage, GlusterFS and Seaweed FS.

Elliptics network is a fault tolerant key/value storage. It was designed to handle all error cases starting from simple disk problems upto datacenter failures. With default key generation policy it implements distributed hash table object storage.
BeeGFS (formerly FhGFS) is a parallel cluster file system, developed with a strong focus on performance and designed for very easy installation and management.

XtreemFS is an object-based, distributed file system for wide area networks. The file system replicates objects for fault tolerance and caches metadata and data to improve performance over high-latency links. SSL and X.
StorPool is an intelligent software-defined storage solution that allows service providers, enterprises and other Cloud builders to run data storage on standard x86 servers, instead of on expensive and inefficient storage arrays (SANs).





Most users think StorPool is a great Ceph alternative.
WekaFS is an extreme-performance parallel filesystem for Linux from WekaIO that works in AWS or on-prem on Industry-Standard Servers. WekaFS includes Enterprise features such as snapshots and tiering to S3 Object Stores.
LINBIT’s DRBD® software seamlessly replicates data between servers, eliminating “single points of failure” within your IT infrastructure, no matter which applications are running on top.
Quobyte is a parallel POSIX file system with block and object storage capabilities. It provides outstanding performance, linear scalability, and full fault tolerance.
LizardFS is a distributed, scalable, fault-tolerant and highly available file system. It allows users to combine disk space located on many servers into a single name space which is visible on Unix-like and Windows systems in the same way as other file systems.
Simplyblock is a software-defined high-performance data storage technology that could be deployed in your own cloud account.

LVM2 refers to the userspace toolset that provide logical volume management facilities on linux. It is reasonably backwards-compatible with the original LVM toolset.
LVM is great but it's volume management, not SDS.

StorPool is a high performance primary block storage system, so it is a good alternative to one of the use cases that Ceph provides, but a really good one in this use case.
