Enterprise VMware environments have tools like vRealize Operations for capacity management. SMB environments running five to twenty ESXi hosts typically don’t — and they don’t need to. Good capacity planning is achievable with PowerCLI, a spreadsheet, and consistent measurement discipline. The Three Resources That Matter For most VMware workloads, three physical resources constrain capacity: CPU, … Read more
VMware vSAN entered the mainstream around 2016 as a hyperconverged storage option — using local drives in ESXi hosts as a shared storage pool, eliminating the need for a dedicated SAN or NAS. For small businesses, the pitch is appealing: consolidate compute and storage, reduce hardware complexity, and lower TCO. The reality is more nuanced. … Read more
vSphere cluster misconfigurations don’t always cause immediate problems. Sometimes they sit dormant for months before a host failure or upgrade event triggers a failure mode that the misconfiguration created. These are the ones I find most consistently when auditing SMB VMware environments. EVC Mode Not Configured Enhanced vMotion Compatibility (EVC) sets a CPU compatibility baseline … Read more
Running standalone ESXi hosts is a common starting point for small businesses. It’s simple, cost-effective, and covers a lot of ground. But there’s a clear inflection point where standalone hosts start to limit you — and adding vCenter is the change that unlocks the rest of the platform. What You Can’t Do Without vCenter Standalone … Read more
The question I got asked most often when starting ESXi deployments for small and mid-size businesses: what hardware should we buy? The honest answer is “it depends,” but there are enough consistent patterns across successful SMB deployments to give useful guidance. The VMware HCL Is Not Optional The VMware Hardware Compatibility List (HCL) exists because … Read more
I’ve deployed both XenServer and VMware ESXi for small-to-medium businesses, sometimes switching between them for the same client as their needs evolved. The right choice depends on several factors that vendor marketing rarely addresses honestly. Where XenServer Wins Cost: XenServer’s free edition covers the core features needed by most SMB deployments — live migration (XenMotion), … Read more
In 2015, I was working with a mid-size client who needed to virtualize roughly 20 servers on a budget that made VMware’s licensing difficult to justify. They’d looked at Hyper-V but didn’t have strong Windows Server Datacenter licensing already in place. XenServer 6.5 was free (for the base edition), mature enough for production use, and … Read more
