How it compares

  • To Ceph

    Ceph is a popular storage software and although its overall concept is basically good, its architecture and implementation are suffering from unnecessary complexity, as it is aiming to solve too many problems at once. It was originally designed as object storage and has evolved to now provide “unified storage”, meaning object, file, and block. It can be seen as being a “Jack of all trades, but master of none”… READ MORE

  • To ZFS

    ZFS and Nexenta, which is based on ZFS, are two popular storage software products on the market. With the rise in popularity and demand for “software-defined storage”(SDS), they each positioned themselves as a “software defined storage”, (SDS) products, however, it would be fair to call them SDS version one. Both are based on a good concept, but their architecture and implementation are already somewhat outdated. StorPool has a … READ MORE

  • To FlexOS(formerly ScaleIO)

    The ex-ScaleIO, now Dell/EMC FlexOS is a block-level SDS product that creates a server-based storage area network (SAN). As we often get questions on how it compares to StorPool, we have outlined some differences. On a very high level it looks similar to StorPool. However, the underlying architectures of the solutions are very different, and the total solution offering around features, business model and pricing vary considerably…READ MORE

  • To All-flash Arrays

    All-flash arrays are essentially a traditional SAN with the twist that they have only SSD drives inside. Their advantage is that they are fast, however, they come at very high cost and are not well suited for some use cases. In addition, they are still a single-purpose, specialized piece of hardware, which imposes vendor lock-in. Their economics do not allow customers to closely match capacity needed with capacity bought… READ MORE
