They cost CPU cycles however CPU cycles are cheap and readily available. NFS clients, like most iSCSI initiator, aren’t free.10 Gbps throughput, very low latency, very low jitter and lossless characteristics that match the fastest FC SANs. This lossless behavior is exactly what is being delivered with Datacenter Ethernet. It’s possible to build “bet the business” Ethernet infrastructure, even including lossless characteristics traditionally associated with Fibre Channel.NAS is widely deployed in the Datacenter today.Never bet against Ethernet! This should be evident today with Cisco’s unified networking architecture. This argument reminds both of us of those who said IP would never be able to provide the quality required for telephone conversations. This is pretty well the opposite of the origins of SANs which originated in the datacenter, ran on “relatively expensive and lossless” (and effective!) SAN design, and with high performance hardware and kernel-mode drivers. In our experience, this is rooted in the fact that NAS originated outside the datacenter (engineering/development), leveraging existing “cheap and dirty” (and effective!) LAN design, and with poor performance client-mode NFS clients running on what at the time where very limited CPU cycles. Often – people are dismissive of NFS performance. Let’s breakdown the myth-busting and best practices into the following: 1) Performance and Scaling 2) High Availability “Is NFS the be-all end-all storage protocol for VMware?” – NO.“Is NFS a good, highly available, high performance option for VMware and deserves equal consideration as with the more traditional SAN choices?” – YES.Ok – let’s get a couple things off the table right off the bat: We try to be good pragmatic voices, so our goal here is pragmatism and facts to help our mutual customers. The reality is only NetApp and EMC are supporting NFS deployments with VMware in significant volume.īoth of us personally are big supporters of NFS for VMware – but if you look at our post histories - we’re both also rational and try our best (we’re human, so sometimes we fail) to be balanced and neutral (in my case, this is a balance to my VMFS post here). While any NFSv3 server will work with VMware, and there are many NFS servers on the ESX HCL, there is a significant difference between what one can do with an enterprise class NFS storage array from EMC or NetApp. We would like to thank Stu Baker and Satyam Vaghani from VMware, along with numerous folks at EMC and NetApp for their input on this post. Heck, if EMC and NetApp can agree – then you KNOW this post is FUD-Free! One of the goals of this post is to dispel the FUD customers often hear around NFS. We apologize for the delay, so without further ado we present to you the followup: a “Multivendor NFS” post for our joint customers. Since the original post, we’ve been busy assisting our customers and partners. ![]() The most difficult part around creating this post is that we couldn’t do it with our iSCSI-focused colleagues. While writing that post, we (Vaughn Stewart from NetApp and Chad Sakac from EMC) discussed following up the iSCSI post with one focused on deploying VMware over NFS. The feedback was overwhelming and very supportive of industry leaders partnering to ensure customer’s success with VMware. We were quite a bit surprised to see how popular our “Multivendor iSCSI” post was. And new themes and styles help you pull it all together to produce stunning, professional documents.UPDATED – June 11th, 8:21pm – new Celerra vSphere Best Practices posted A refreshed task pane interface makes positioning, resizing, or rotating graphics easy so you can create exactly the layout you want. The redesigned ribbon intuitively organizes features so you can quickly find what you need quickly. We've modernized the user experience and made it easier to get things done. ![]() The new Office 2016 for Mac includes updated versions of Word, Excel, PowerPoint, OneNote and Outlook-and the moment you open any one of the apps, you'll immediately feel the difference. The new apps offer full retina display support with thousands of retina-optimized graphics, full screen view for native immersive experiences, and even little Mac affordances like scroll bounce. It's unmistakably Office - but thoughtfully designed to take advantage of the unique features of the Mac. Office 2016 for Mac is powered by the cloud so you can access your documents anytime, anywhere, and on any device. You will receive regular updates automatically until the official release in the second half of 2015. Preview the new and modern Office for Mac.
