Navigating the DRAM Crisis: Memory Tiering in vSphere 9
Recently, I wrote an article about how shocked I was by the increase in memory costs for a laptop I was reviewing. Yes, I was aware of “RAMageddon” and how the price of RAM has escalated over the past year, but I didn’t realize some DDR5 memory kits that sold for around $50 a year earlier were selling for well over $200, illustrating just how volatile the DRAM market has become. This really drove home two things: the effect of rising RAM prices on infrastructure vendors and the need for me to investigate VMware’s Memory Tiering, which VMware positioned as a way to reduce the amount of DRAM required by hypervisors. I first heard about it at a VMware Explore event a few years ago, and then again at a local VMware User Group meeting I attended.
