Right-sizing the physical host — vCPU, RAM, storage & networking
A VM host server is only as reliable as the physical hardware underneath it. Emirtech addresses compute, storage and networking together as part of a coherent host design rather than treating them separately — because mismatches between any of these layers cause performance problems that are difficult and expensive to fix after deployment.
vCPU and core allocation: Emirtech maps the CPU demand of each planned VM against the physical core count of the host, establishing safe vCPU-to-pCPU ratios for the workload mix. Server roles such as SQL databases, ERP engines and virtualised domain controllers have different CPU profiles, and the host is sized to accommodate realistic concurrent peak demand rather than theoretical averages.
RAM sizing with HA headroom: Memory is typically the first constraint in a consolidated VM environment. Emirtech sizes host RAM to cover all planned VMs at realistic working-set sizes, plus a headroom allowance for memory ballooning under peak load and, where HA failover is required, the overhead of absorbing a second host's VMs in a cluster scenario.
Storage — local NVMe, NAS or SAN: The right storage architecture depends on whether a single host or a shared-storage cluster is needed. Emirtech configures local NVMe or SATA SSD datastores for single-host deployments and integrates shared NAS (NFS or SMB) or iSCSI SAN storage for multi-host environments requiring live migration. Thin provisioning and snapshot scheduling are configured from day one.
Virtual networking: Virtual switches, VLANs for VM-to-VM isolation, a dedicated management network and, where storage traffic justifies it, a separate 10 GbE network are all defined during the host design. Emirtech's networking background — covering structured cabling, managed switches and firewall configuration — means this layer is correctly specified rather than left as an afterthought. See our IT infrastructure services overview for the wider context of how the VM host integrates with your network.

- Workload profiling — CPU peaks, RAM working sets, storage IOPS and growth trajectory before any hardware is specified
- Physical host selection sized for all planned VMs with realistic headroom, not minimum specification
- Hypervisor installation and configuration — VMware ESXi, Proxmox VE or Hyper-V
- vCPU and RAM allocation per VM, with resource pools or reservations where workloads compete
- Virtual networking — VLANs, virtual switches, management network separation, 10 GbE storage fabric where required
- VM-level backup configuration — snapshots, Veeam or open-source tools, retention policy and verified restore testing
- Full handover documentation and AMC option for monitoring, patching and ongoing support
