Hyperconvergence backline: How to make sure that your hyperconverged environment rocks?

Admins love hyperconvergence because it allows conjoining compute, storage, and networking resources that makes the environment cheaper and easier to manage. Experienced users can build an infrastructure in different ways using any parts. For instance, you can grab some servers from Dell and install an industry-standard hypervisor (Hyper-V, KVM, ESXi, whatever) on top of them. If you do not know that much about hyperconvergence though, consider buying an appliance.

Log-structured Write-Back Cache – forget about post-blackout full syncs

Let’s imagine a situation: a power outage went out and an incorrect server shutdown has occurred. Everything is aggravated by the fact that you have no power backup. What will happen to your write operations? They sink into oblivion and data will be lost. But StarWind says “no” to these troubles! Log-structured Write-Back Cache (LSWBC) is a StarWind feature which speeds up the processing of write requests and saves data when the server is incorrectly shut down. What about RAM caching? Your data also will be saved.

Storage Tiering – the best of both worlds

Before the time when SSDs took their irreplaceable place in the modern datacenter, there was a time of slow, unreliable, fragile, and vacuum filled spinning rust drives. A moment of change divided the community into two groups – the first with dreams of implementing SSDs in their environment, and the second, with SSDs already being part of their infrastructure. The idea of having your data stored on the associated tier has never been so intriguing. The possibility of granting your mission-critical VM the performance it deserves in the moment of need has never been more appropriate.
