Frame vs. frame-less storage

28 July 2015
Comments off

Reading Time: 2 minutesOne old (and now quite not used anymore) storage concept was about the Frame vs. frame-less architectures. Those terms are from the past decades and where used (especially from Dell-EqualLogic) to identify how storage controllers are dedigned and how they can scale: Frame-based storage contain individual components that scale independently (you can add more cache, network connections, disks, software, etc.) until it’s maxiums and until the product is still supported. Usually you have two storage controllers and one ore more shelves of disks. Frame-less storage is modular where each “module” include it’s own storage processors, […]

Reading Time: 3 minutesHistorically, Nutanix was built around iSCSI but then they have add the ability to run NFS as well as other front-end IP based protocols. Starting from version 2.5, NFS/NDFS has become the preferred protocol for the Nutanix cluster. Although the Nutanix Distributed File System (NDFS) is stretched across all nodes and build on the pool of each local storage resource, all I/O for a VM is served by the local CVM. The storage can be presented via iSCSI, NFS or SMB3 (introduced in NOS 3.5) to the hypervisor from the CVM (not only the local, […]

Reading Time: 3 minutesOne of the big announces at the .NEXT Conference, was the introduction of erasure coding across nodes (in RAIN configuration) in Nutanix Operating System (NOS) version 4.1.3 (actually it’s a tech preview). Nutanix Erasure Coding–X (EC-X) is a proprietary, native, patent pending, implementation of Erasure Coding. With EC-X, Nutanix customers are able to increase their usable storage capacity by up to 70%. As written in a previous post, Erasure Coding (EC) is a way to implement data proctection in storage systems instead of using RAID techniques.
