2 TB datastores? The underlying storage is comprised of all SSDs. Now, regarding load balancing, if you have multiple IPs on your NFS/iSCSI store, then you can spread the load of that traffic on more than one NIC, similar to having sw iSCSI initiators in your VM's, and I've seen arguments to both, but I generally don't like to do anything special in my VM's, and have my ESX abstract the storage from them, and prefer to manage that storage on the host side. To demonstrate, I'll connect a vSphere host to my Drobo B800i server that is an iSCSI-only SAN. The only version I so far has been found stable in a prod env is iscsi and firmware 3.2.1 Build 1231. In this paper, a large installation of 16,000 Exchange users was configured across eight virtual machines (VMs) on a single VMware vSphere„¢ 4 server. Our workload is a mixture of business VMs - … As you can see, with identical settings, the server and VM workloads during NFS and iSCSI testing are quite different. ... Connect the Veeam machine to the storage box via iSCSI. According to storage expert Nigel Poulton, the vast majority of VMware deployments rely on block-based storage, despite usually being more costly than NFS. Unfortunately, using guest initiators further complicates the configuration and is even more taxing on host cpu cycles (see above). Some of the database servers also host close to 1TB of databases, which I think is far too big for a VM (can anyone advise on suggested maximum VM image sizes?). We have a different VM farm on iSCSI that is great (10GiB on Brocades and Dell EQs). Fibre Channel and iSCSI are block-based storage protocols that deliver one storage block at a time to the server and create a storage area network (SAN). NFS also offers a few technical advantages. There have been other threads that state similar to your view, that NFS on NetApp performs better than iSCSI. The question I have is in relation to the connection protocols to the storage. Image 2 – CPU workload: NFS vs iSCSI, FIO (4k random read) Now, let’s take a look at VM CPU workload during testing with 4k random read pattern, this time with FIO tool. Experts debate block-based storage like iSCSI versus file-based NFS storage. All of the later ones has had glitches etc. The ESXi host can mount the volume and use it for its storage needs. As Ed mentioned though, iSCSI has its own benefits, and you won't be able to hold your RDM's on NFS, they will have to be created on a VMFS. For most virtualization environments, the end user might not even be able to detect the performance delta from one virtual machine running on IP based storage vs. another on FC storage. The same can be said for NFS when you couple that protocol with the proper network configuration. vmwise.com / @vmwise One thing I keep seeing cropping up with NFS is that it is single data path only, with iSCSI I can put round robin load balancing in natively with VMware. SAN versus NAS and iSCSI versus NFS are long-running debates similar to Mac versus Windows. iSCSI vs NFS has no major performance differences in vSphere within that small of an environment. Now that we're moving to 10gb we decided to test NFS vs iSCSI and see exactly what came about. Preparation for Installation. And it allows you to mount an NFS volume and use it as if it were a Virtual Machine File System (VMFS) datastore, a special high-performance file system format that is optimized for storing virtual machines.

First, you must enable the iSCSI initator for each ESXi host in the configuration tab, found under storage adapters properties. A single powerfailure can render a VMFS-volume unrecoverable. NFS data-stores have been in my case at least susceptible to corruption with SRM. Now, with NFS, you can also use jumbo frames which will help your throughput as well, so I may go with an NFS store until I had some concrete numbers to weigh the two.

NFS and iSCSI have gradually replaced Fibre Channel as the go-to storage options in most data centers. NFS in VMware: An NFS client built into ESXi uses the Network File System (NFS) protocol over TCP/IP to access a designated NFS volume that is located on a NAS server.

We've been doing NFS off a NetApp filer for quite a few years, but as I look at new solutions I'm evaluating both protocols. In this example, I use static discovery by entering the IP address of the iSCSI SAN in the static discovery tab. Both ESX iSCSI initiator and NFS show good performance (often better) when compared to an HBA (FC or iSCSI) connection to the same storage when testing with a single VM.

The performance of this configuration was measured when using storage supporting Fibre Channel, iSCSI, and NFS storage protocols.

NFS in my opinion is cheaper as almost any thing can be mounted that is a share. Currently The SQL servers are using iSCSI LUNs to store the databases. NFS and iSCSI are pretty much different from each other. Almost all servers can act as NFS NAS servers, making NFS cheap and easy to set up. Lenovo EMC PX2-300d VMware Performance – NFS vs iSCSI I recently purchased a Lenovo EMC PX2-300d 2-bay NAS and wanted to establish a performance baseline for future troubleshooting. Now, regarding load balancing, if you have multiple IPs on your NFS/iSCSI store, then you can spread the load of that traffic on more than one NIC, similar to having sw iSCSI initiators in your VM's, and I've seen arguments to both, but I generally don't like to do anything special in my VM's, and have my ESX abstract the storage from them, and prefer to manage that storage on the host side. If you need NFS 4, you’ll need to use VMware version 6. This is the reason why guest initiators can offer better performance in many cases due to the fact that each guest initiator has it's own IP an thus the traffic from the guest initiators can be load balanced over the available nic's. Though considered a lesser option in the past, the pendulum has swung toward NFS for shared virtual infrastructure storage because of its comparable performance, ease of configuration and low cost. However, with dedicated Ethernet switches and virtual LANs exclusively for iSCSI traffic, as well as bonded Ethernet connections, iSCSI offers comparable performance and reliability at a fraction of the cost of Fibre Channel. Will VMWare run ok on NFS, or should we revisit to add iSCSI licenses? Please check the box if you want to proceed. Operating System: NFS works on Linux and Windows OS whereas ISCSI works on Windo… The client currently has no skilled storage tech's which is the reason I have moved away from a FC solution for the time being. I weighed my options between FC and iSCSI when I setup my environment, and had to go to FC. Many enterprises believe they need an expensive Fibre Channel SAN for enterprise-grade storage performance and reliability. FCoE is a pain and studies show that it generally doesn't quite keep up with iSCSI even though iSCSI is more robust. At the logical level of a … Just my opinion, but I doubt that those "heavy duty SQL databases" will run ok on NFS or iSCSI, if it is one thing that would help run them in near native speed, it's fast storage I think. Note that an RDM will not work over NFS, you will need to use a VMDK. To use VMFS safely you need to think big - as big as VMware suggests. For example, I am installing Windows 2012 at the same time - one to a NFS store and the other to iSCSI and I see about 10x performance increase in milliseconds it takes to write to the disk. Let us look at the key differences: 1. If you have printer redirection issues with the Remote Desktop Protocol in RDS, check user ... Finding the right server operating temperature can be tricky. Is there anything in particular I cant do if we go down the NFS path? We have learned that each of VMware hosts is able to connect to the QES NAS via NFS. Any thoughts on NFS vs iSCSI with > 2 TB datastores? The underlying storage is comprised of all SSDs.
