What is Esxtop in VMware?
Esxtop is essentially a VMware version of top, the Linux command line that displays real-time CPU information. The tool runs in the Linux-based Service Console, which means it only supports VMware ESX hosts. For ESXi hosts, VMware offers a tool called resxstop.
What is a minimum disk controller requirement for VMware vSAN?
The memory requirements for vSAN depend on the number of disk groups and devices that the ESXi hypervisor must manage. Each host must contain a minimum of 32 GB of memory to accommodate the maximum number of disk groups (5) and maximum number of capacity devices per disk group (7).
What is a requirement of storage I O control?
Storage I/O Control has several requirements and limitations. Datastores that are Storage I/O Control-enabled must be managed by a single vCenter Server system. Storage I/O Control is supported on Fibre Channel-connected, iSCSI-connected, and NFS-connected storage. Raw Device Mapping (RDM) is not supported.
What is CPU ready in VMware?
CPU ready time is a vSphere metric that records the amount of time a VM is ready to use CPU but was unable to schedule physical CPU time because all the vSphere ESXi host CPU resources are busy. CPU ready time is dependent on the number of VMs on the host and their CPU loads.

How does NUMA work in Vmware?
The virtual CPUs of the virtual machine are constrained to run on the home node to maximize memory locality. The NUMA scheduler can dynamically change a virtual machine’s home node to respond to changes in system load. The scheduler might migrate a virtual machine to a new home node to reduce processor load imbalance.
What is NUMA configuration?
NUMA (non-uniform memory access) is a method of configuring a cluster of microprocessor in a multiprocessing system so that they can share memory locally, improving performance and the ability of the system to be expanded. NUMA is used in a symmetric multiprocessing ( SMP ) system.

What is NUMA nodes per socket?
CPUs and local memory banks are referred to as NUMA nodes. For example, in a two-socket server each of the two CPUs has a local memory bank for a total of two NUMA nodes. When a CPU uses the local memory bank memory access is very fast.
What is NUMA nodes in vmware?
NUMA is an alternative approach that links several small, cost-effective nodes using a high-performance connection. Each node contains processors and memory, much like a small SMP system. However, an advanced memory controller allows a node to use memory on all other nodes, creating a single system image.
Where is NUMA node in Windows?
Start with the Windows Task Manager | Process Tab. Select a process, Right Mouse | Set Affinity — the following dialog is presented showing you the Processor Groups (K-Group), Nodes and CPUs on the machine. This is the layout presented to SQL Server.
