When we asked over 350 IT managers about virtualisation, they confirmed our research and expectations. More memory meant better virtualisation across the board, but many IT departments weren’t using enough RAM to achieve acceptable levels of virtualised application performance. The pattern held across nearly all industries and all countries surveyed, and at companies running a minimum of 30 physical servers to upwards of 200. Here’s what IT pros had to say about virtualisation and memory – and how you can use it to optimise your server infrastructure.*
On average, IT managers are running about 29 VMs per physical server
Over 60% of IT managers said the amount of memory they allocated per VM was “very” or “extremely” important – for nearly every major virtualised server application (Big Data and analytics, databases, content hosting, email, web hosting, file sharing, and content creation)
Nearly a third (32%) of IT pros said unexpected/unpredictable workload demands are a challenge their organisation currently faces
Only 46% of IT pros say the amount of memory they have installed is sufficient for their current workload needs
Nearly half of all IT managers (47%) plan to upgrade their RAM within the next year
There’s no doubt that virtualised workloads will grow. The only question is ... by how much? And in what ways? Only you know enough about your company to accurately estimate how much DRAM you’ll need. However, one thing is certain: you’ll likely need more than you’re using today, since tomorrow’s bigger workloads will require more memory.
Server memory is a long-term investment that’s never just about today’s workload. It’s also about foreseeable future workloads because memory is often the limiting factor. Get as much as possible out of your IT budget by identifying high-growth, business-critical applications and then installing future-proofed 32GB modules to deliver optimal QoS and scalability at a typically lower price than that of multiple lower-density modules.Shop Crucial server memory
