Architecture without Hyper Converge

(Decoupling storage performance from capacity and data services)
A new “decoupled” architecture has emerged that addresses the issues discussed in the previous post. Like hyper convergence, it puts storage performance in the server, using high-speed server media like flash (and RAM). But unlike hyper convergence, it leaves capacity and data services in shared storage arrays

There are several benefits that come with separating storage performance from capacity:

  • Fast VM performance by putting CPU Centric or All Flash Centric share storage intelligence.( UNITY All Flash Array, Nimble Hybrid Array , HP 3PAR All Flash Array using eMLC SSD Drives only )
  • No vendor lock-in, as decoupled architectures leverage any third-party server and storage hardware
  • Cost effective scale-out. Additional storage performance can be easily added simply by adding more server media. Capacity is handled separately, eliminating expensive over-provisioning.
  • No disruption. Decoupled software is installed inside the hyper visor with no changes to existing VMs, servers or storage.
  • Easy technology adoption. With complete hardware flexibility, you can ride the server technology curve and leverage the latest media technology for fast VM performance (E.g. SSD, PCIe, NVMe, DRAM, etc.).

Once in place, a decoupled storage architecture becomes a strategic platform to better manage future growth. Because performance and capacity are isolated from one another in this structure, they can be tuned independently to precisely meet the user requirements. Going back to the previous example of a service supported by a two-node cluster, performance and capacity can now be added separately, as needed, to reach the desired service level without over provisioning.

IT operators are often faced with the desire to gain a competitive edge by adopting new technology while ceaselessly looking to mitigate risk. Often, one has to be prioritized above the other. In the case of hyper convergence, pushing the innovation envelope involves compromising flexibility and accepting institutional changes to fundamental operating procedures in the data center.

Decoupled storage architectures, on the other hand, offer the rare opportunity to take advantage of two major industry trends — data locality and faster storage media — to speed virtualized applications in a completely non-intrusive manner. In essence, all the performance benefits of hyper convergence without any of the disruption.
