Software defined storage allows for the pooling of different storage hardware, enabling users to fully utilise their existing infrastructure thus avoiding unnecessary, more costly hardware overhauls.
In essence, you are creating a virtual software layer that virtualises all of the underlying storage, providing the networking protocols your application requires i.e. fibre channel.
Once your infrastructure has been virtualised, it’s easy to optimise, and re-design your storage layout. Users can carve up their storage estate and disperse as and where it’s most needed.
Software defined storage manages all of the different types of storage; hard disk, SSD, flash NVMe
, memory. Software defined storage boosts the performance of your storage by adding a software layer that controls all of the I/O from all of the different storage types.
Software defined storage typically runs on x86 servers and sits in the data path between the application/users and storage hardware, normally these are sold as storage nodes which provide active-active mirroring to protect your data. With auto-failover and failback with a stretch cluster of up to 100km.
Software defined storage also supports auto-tiering to migrate the least used data to less performing tiers. This is an extremely useful function, and yields amazingly powerful results from an ROI perspective.
If you needed a new storage array you stuck with what you bought historically as you already had the management software in place or you bought a whole new storage array from a new vendor and installed the new management software and this is how things progressed for decades.
Vendor lock-in was common and you were forced to pay the price for replacement drives, on-going support etc. If you needed iSCSI you bought a dedicated device for that task.
As time went by a business would have storage pools providing different performance, disk capacity and network interfaces, along with incompatible hardware from the storage vendors.
This causes data sprawl, maintenance and management become increasingly expensive as time goes on and you end up maintaining an IT infrastructure that consists of monolithic storage that doesn’t really handle the agility or flexibility the business needs in order to grow.
Either you scrap everything and start again or add more storage pools, whilst the cycle continues.
