The most prominent trend of 2017 in storage and backup was the rise of hyper-converged infrastructure.
First it emerged for primary use cases, with compute and storage in a single node that could be scaled out to build hyper-converged clusters. Then backup product makers started to sell appliances built on the same architecture.
Meanwhile, the next big thing in flash storage has been bubbling under. NVMe promises to unleash the potential of flash that has been locked in by protocols built for spinning disk. So far, however, the NVMe market is struggling to find maturity and an agreed way of overcoming key obstacles.
In the background, object storage continues its rise, while the industry looks ahead to what will supercede flash and potential new ways of doing cloud storage based on blockchain.
Hyper-converged was a big story in 2017 and is set to remain so in 2018. Here, Forrester rates 12 hyper-converged infrastructure providers according to products, company strategy and market presence, with Nutanix, Simplivity and Pivot3 coming out on top.
Property firm Colliers replaces NetApp converged stacks with hyper-converged infrastructure. Hyper-converged secondary storage and backup from Cohesity replaces tape and supports Nutanix performance tier.
As numerous storage suppliers try to come up with a way to provide shared storage based on NVMe while overcoming the bottleneck at the controller, this blog article from August takes stock of the approaches taken.
Vivavo runs Excelero NVMesh NVMe storage at claimed near-bare metal performance to support real-time analytics for face and behaviour recognition on CCTV.
Thekking scraps ageing IBM and HPE iron for Cohesity hyper-converged nodes with hybrid flash capacity to power deduplication for Veeam backups.
An example of how backup products are changing. Not only are we seeing hyper-converged products, but suppliers are looking to exploit data captured in backup and archive operations to gain intelligence for the organisation.
SNIA Europe director says traditional SAN and NAS are not built for the stateless world of web-based apps and workloads, with object storage set to become dominant.
New solid state technologies such as 3D XPoint will be a second tier of memory, bringing change to hardware architectures and causing software to be rewritten, says SNIA solid state group chair.
Millennium Prize winner Stuart Parkin says flash and 2D methods of storage are fatally limited – Racetrack Memory offers 100x the capacity without the wear issues of flash.
Already some companies allow customers to store data on the hard drives of strangers, encrypted and protected by blockchain, and at a fraction of the price of mainstream public cloud services. What future is there for distributed cloud storage?
