“What the future holds for data centres, what major transformation can we expect by 2020? A sneak peek at the next evolution of servers, networking and storage in coming years”
With IT moving at light speed and transformation has no end to it;the answer is complicated as to what data centres would look like in the next four years and impacting factors. From 2015 onwards, almost every industry has been through the highest rate of change and by 2020; servers and storage are expecting a huge leap within the timeframe. For better understanding, we need to look at core technologies first so let’s review the trends.
The convergence or hyper convergence of storage units and servers into a single box is the cult driven by the super-fast Non-volatile Memory express (NVMe), the solid-state drives (SSD) saturating the hosts with six drives or even less. We see it as a healthy amount for a server box moved with the idea of placing drives in servers without isolating networked storage boxes; and it just makes sense!
Perhaps due to under optimised I/O paths, software such as Virtual Storage Area Network (vSAN) by VMware lacks the performance required to fit with the situation. It leaves room for some supplementary motherboard or any other server optimisation as well as better LAN connectivity inside the data centres of tomorrow. With Ethernet taking the leap in performance with added RDMA capability, the latter issue would resolve automatically in times to come.
Server-side motherboard is entirely a different changing measure as everything is right on the table clear and elucidated from strong connection among Dynamic Random Access Memory (DRAM) and CPUs to concurrent memory compression.
We’re also seeing persistence of memory approaching DRAM with 3D X-Point Dimm-based offeringsthat grows almost 2.5 times the dormancy of DRAM whereas using 3D X-Point as the NVMe NAND alternative drive. In this case, the X-Point is typically 10-times faster than the already fast drives that’ll change the very structure of top line servers considerably however, assuming a realistic price.
In the near future, servers within a typical data housing facility will manage hundreds of operations in a rather streamlined way. It’ll lead to major reduction in server count thus providing additional space. The new breed of servers can easily process tens of terabytes effectively for the DRAM as well as majority of database systems as a result would move to the in-memory model.
Storage units as well are evolving radically and surprisingly to cope with the imminent needs of a data warehouse. We’re expecting all major SSD storage products as a finer alternative to the bulk hard drive two tier boxes by 2020. Whereas, some form of localised PCIe drives or vSANwould provide a best and primary storage.
All backup and archived files will shift to the public cloud while it’s possible a certain degree of secondary storage will migrate as well to resolve the public cloud storage latency. The critical change in data centres is deemed more a philosophic and software shift based on defined and imminent technological revolution. The Software-defined infrastructure is likely to rule in 2020 with approaches similar to those with server orchestration management.
User control will extend to virtual infrastructure and on-demand service with the traditional administration setup, configuration and maintenance tasks will be history. The admin skillset here will divert towards devising and implementing policies instead of tweaking through tangible IT equipment.
The hyper-converged systems will come ready-to-be-used whereas isolated system components can easily configure into the infrastructure automatically thus transforming the traditional setup into new.
By 2020, all such approaches would be antiquated and creating considerable work within software admin space during evolution.
The existing software and software as a service (SaaS) still require major business process redesign thus benefiting system analysts and software admins.
Growing trend in cloud computing and full orchestration with shrinking data centreswill transform the role of central IT from the core.
