XenServer 6.5 SP1与ESXi 6 - Dell R720 GRID K2

你好
知道其他人是否经历过类似的结果以及他们的想法是很有趣的...
随着关于VMware的所有“嗡嗡声”终于赶上Citrix并支持vGPU，我想看到2个最新的Hypervisor之间的性能差异，因为我听说ESXi 6 3D体验优于XenServer 6.5 SP1。
VMware被广泛认为是行业领先的Hypervisor，但是对于所有额外的功能和（所谓的）性能，您需要付出相当大的代价，因此我总是使用XenServer，它完全按照要求执行并执行了
奇妙地以一个价格点取悦所有会计师。
然而，调查其他解决方案总是好的，所以考虑到这一点，我破坏了我非常好的XenServer 6.5 SP1 3D演示平台并使用ESXi 6重建它。构建与XenServer完全相同，唯一的变化是
技术堆栈是Hypervisor，因此在重建平台，vCenter，Gold图像等所有工作之后，想象一下当XenServer在我运行的每个3D演示中执行ESXi时我会感到惊讶。
无论3D桌面是Windows 7,8.1还是10，在XenServer上运行它都会显示出比ESXi更高的基准。
我知道这些只是通用的3D应用程序，你不应该将整个平台的性能建立在一些不相关的分数上，而且必须根据实际运行的特定应用程序进行设置，但它们似乎很奇怪
所有（到目前为止）都支持XenServer。
由于与ESXi相关的成本太高，我认为它应该比其竞争对手更好。
我正在使用GPU Passthrough / vDGA运行桌面。
在这一点上，我应该说一下技术堆栈，以防万一我在看东西，所以它如下：
机箱：Dell R720（最新固件，驱动程序，BIOS等）
CPU：2x 2.6Ghz 8 Core
内存：256GB
存储：2x 15k SAS RAID 1（管理程序）
存储：5x 15k SAS RAID 5（黄金映像，虚拟设备）
存储：Atlantis ILIO无盘VDI（从RAID 5  -  2vCPU / 128GB RAM运行）
GPU：NVIDIA GRID K2
网络：1Gb到桌面（整个硬连线，此测试没有WiFi）
软件：XenDesktop 7.6 FP2 Platinum（MCS到ILIO）
桌面策略：仅基本安全性，无其他策略。
我有一个单独的服务器，其上有我的所有其他服务（AD，Controller，vCenter等），但这还没有重建并在XenServer上运行。
性能在视觉上并没有太大差异，但在查看（例如）Unigine Valley / Heaven，Redway Turbine等基准测试时，结果总是有利于XenServer提供的台式机，说实话，我真的没想到
情况就是这样。
还有其他人经历过这个吗？
或者我在ESXi中遗漏了哪些内容会释放我应该启用或禁用的其余性能？
关于这两项技术的任何想法，评论或经验都受到欢迎......这不是VMware抨击线程（远非如此），我只是没有看到有人对这两者之间的3D性能进行直接比较。
问候

Hi

It would be interesting to know if others have experienced similar results like the following and what their thoughts are...

With all the "buzz" about VMware finally catching up with Citrix and supporting vGPU, I wanted to see the performance differences between the 2 latest Hypervisors as I had heard that the ESXi 6 3D experience was better than XenServer 6.5 SP1. VMware is widely recognized as the industry leading Hypervisor, but for all the extra features and (alleged) performance, you pay a substantial premium over the others, so I've always used XenServer which has done exactly what has been requested of it and performed fantastically at a price point to please all the accountants. However, it's always good to investigate other solutions, so with this in mind, I trashed my perfectly good XenServer 6.5 SP1 3D demo platform and rebuilt it with ESXi 6. The build is exactly the same as it was on XenServer, the only change in the technology stack is the Hypervisor, so after all the work of rebuilding the platform, vCenter, Gold images etc etc, imagine my surprise when XenServer out performs ESXi on every 3D demo I run. Whether the 3D desktop is Windows 7, 8.1 or 10, running it on XenServer shows higher benchmarks than ESXi. I know that these are just generic 3D apps and that you shouldn't base the entire platforms performance on some irrelevant scores and that settings have to be tailored to the specific apps that are actually going to be run, but it just seems strange that they all (so far) favour XenServer. As there is so much more cost associated with ESXi, I would have thought it should perform better than its rival.

I'm running the desktops with GPU Passthrough / vDGA.

At this point, I should say a little about the technology stack in-case I'm over looking something, so it's as follows:

Chassis: Dell R720 (latest firmware, Drivers, BIOS etc)
CPU: 2x 2.6Ghz 8 Core
Memory: 256GB
Storage: 2x 15k SAS RAID 1 (Hypervisor)
Storage: 5x 15k SAS RAID 5 (Gold Images, Virtual Appliances)
Storage: Atlantis ILIO Diskless VDI (Runs from the RAID 5 - 2vCPU / 128GB RAM)
GPU: NVIDIA GRID K2
Network: 1Gb to desk (hard wired throughout, no WiFi for this test)
Software: XenDesktop 7.6 FP2 Platinum (MCS to ILIO)
Desktop Policies: Only base security, no other policies.

I have a separate server that has all my other services on it (AD, Controller, vCenter etc etc) but this has not been rebuilt and runs on XenServer.

The performance isn't hugely different visually, but when looking at the benchmarks on (for example) Unigine Valley / Heaven, Redway Turbine etc, the results always favour the desktops delivered by XenServer, and to be honest, I really didn't think this would be the case.

Has anyone else experienced this? Or is there something I've missed in ESXi that's going to unleash the rest of the performance that I should have enabled or disabled?

Any thoughts, comments or experiences about the 2 technologies welcomed... and this isn't a VMware bashing thread (far from it), I just haven't seen anyone do a direct comparison of 3D performance between the pair.

Regards

Ben
