The only key management feature that is supported by both software programs is Thin Provisioning.One area where these programs tend to differ - and to a large extent explains the disparity in acceptance and usage levels between the two - is virtualization management. However, XenServer does not have any virtual CPUs on the host.Īlso Read: VMware vSphere Best Practices Virtualization Management Features Both systems have 160 (hundred and sixty) logical CPUs per host with the VMware capable of having a total of 2048 virtual CPUs per host.XenServer has a total pack of 75 (seventy-five) virtual machines per host with a RAM of 1024GB per host and 512 virtual disks per host.VMware vSpher e has a total of 120 (hundred and twenty) virtual machines per host with the RAM per host being at 2048 GB with a total of 2048 virtual disks per host.
On the other hand, VMware vSphere ESXi has a total of 10 virtual NICs per virtual machine and a whopping 62 virtual disks per virtual machine. XenServer provides a total of 7 Virtual Network Interface Cards (NICs) per virtual machine and 16 virtual disks per virtual machine. The XenServer has a total of 16 virtual CPUs per Virtual Machine (VCPUs) and VMware has double this, at 32 VCPUs. Virtual Machine Limitsīoth these software programs have a virtual disk size of 2000 GB, but the RAM per virtual machine does vary with VMware since it offers a staggering 1024 GB while the Citrix XenServer offers 128 GB per virtual machine. Both products do have a substantial client following dotted all over the globe irrespective of their pricing structure.

Both of them support DAS, FC, and NAS storage while neither of them supports eSATA or RDM.
The difference between them, when it comes to virtualization, is that VMware does support FCoE and SSD for Swap and does not support USB, SATA, SAS, NFS, iSCSI-which are all supported by Citrix XenServer. Neither support operating system virtualization, which you can learn more about in our article on VMware vSphere Best Practices.īoth software suites support a variety of storage options.

Though they support various types of virtualization such as hardware-assisted virtualization and paravirtualization, only VMware vSphere ESXi does support full virtualization. Technical Specificationsīoth of these software programs run the Bare Metal (Type 1) hypervisor type and support x86 and 圆4 architecture. The Citrix XenServer is used by personal users and small to medium-sized businesses, while VMware vSphere ESXi is only intended for small to medium-sized businesses and is not structured for personal use. The main difference between the two is the intended usage of the software. Though they perform similar roles, they do have a few distinct differences which make them unique. The VMware vSphere ESXi is developed by VMware Inc., whereas XenServer is developed by Citrix. When assessing the pros and cons of Citrix XenServer compared to VMware vSphere ESXi, the first thing to note is that these two software systems are developed and supported by different companies.
