StarWind SAN & NAS is an HCL-certified software-defined shared storage for VMware vSphere and Microsoft Hyper-V. The solution also enables the user to repurpose servers into certified backup targets if they are using Veeam. StarWind SAN & NAS, as a Linux-based VM, leverages all the features of ZFS to ensure optimal storage use, data safety and integrity. The solution is designed to present a unified,…
Longhorn is performing well as storage for databases and in almost any solution that uses exclusive access to volumes (ReadWriteOnce in Kubernetes nomenclature). When write access is required from many clients (ReadWriteMany) Longhorn Block Storage covers its volumes with NFS (file-based) access. Longhorn Block Storage also is well fitted in every architecture where data security (snapshots, backups, multiple replicas) is more important than access speed (in terms on IOPS and MiB/s).
StarWind is best suited for the integration and deployment part and for the storage part as well. The product is budget-friendly and helps us to improve business agility. Can't think of negative scenarios as of now.

ReadWriteMany Longhorn volumes are still using NFS (file-based) protocol in the core.
Using iSCSI as main protocol instead of FC ties Longhorn to Ethernet-based LAN which is in most architectures much slower that FC-based SAN.
Longhorn could implement S3 as alternative access protocol to its volumes.
Backups, and snapshots configuration could be configured at each volume-level by administrators (maybe from additional CRD object?), because currently is configured at storage-class level which is not granular enough.

Longhorn is mature software defined storage solution that is still developed and receive new functionalities. From the beginning every Longhorn volume have multiple (at least two) replicas, can leverage manual or automatic snapshots and backup to external S3 volume. Longhorn provides nice and clear GUI for administrators, but also can be managed from CLI.
GlusterFS was first Persistent Storage solution used in our Kubernetes-based clusters. It is file-based what in some usages led us to many data corruptions. CEPH is object-based persistent storage which can be used as file-based Persistent Storage in Kubernetes. It is also is much more resource-hungry than other solutions including Longhorn. Dell PowerScale (or Isilon) is a hardware-software solution, that provides volumes that can be accessed by file-based NFS and CIFS protocols. Recently was added access to its volumes with object-based S3 protocol. Longhorn is in the middle. It is block-based, it is build on industry standards like iSCSI, performs very well on 10Gbit or faster LAN and commodity hardware (or in virtual machines)
