John: Hyper convergence is obviously a big trend right now. there are a lot of options out there and you want to do your homework before you jump in. so we are going to go over a couple of the Dell and Emc offerings and what they feel and why we feel Dell and Emc is a right fit for a lot of customers. So we are going to bring up the slides in a minute here and then we will get right into it and obviously like Rachel said any questions please post them in the chat and we will answer them along the way. Ok so Dell Emc has a couple of different offerings for hyper converged and we are going to discuss 2 of them today. The first one we are going to discuss is VxRail and the second one is VxRack. VxRail is you may have heard about it. It is appliance based Vsan, Vsphere, VMware only appliance. Can grow up to anywhere from as small as 3 nodes all the way up to 64 nodes. There are a handful of different configurations you have that we will go over for that. The VxRack is a little bigger. There are 2 different options with VxRack. A flex or an SDDC. The main difference is the SDDC is based off of VMware’s Vstand and the flex is based off of Dell Emc scale IO. It is a lot larger, obviously there you can scale over 1,000 nodes with the VxRack Flex which is quite large. But you can again start as small as 4 nodes and we will go over the options and the differences as we continue. Next slide, Rachel. So here is the difference VxRail nodes. So as I said there is 5 different nodes. On the left side there is the G series. The G series is your smallest footprint, 4 nodes in 1-2U appliance. It is a really great starting point, really great for VDI solutions for remote offices. Good growth, good balance between compute and storage. E series is a 1U entry level small and again you can start with 3 nodes in any one of these options. V series is a VDI optimize it has GPU’s and a handful of different GPU offerings both from Intel or NVidia that you can go with. Your P series or your performance you are going to have higher performance CPU, memory built in there. It is a 2U node and then the S series is storage heavy. So you can go up to 48 terabytes in one node and the good thing about this is you can mix and match these. The one requirement is the first 4 have to be the same type of node. Once you go past there you could add a storage node, you could add a performance heavy node and all of them except for storage have either all flash or hybrid. The storage heavy node is only hybrid. So that is going to have some caching with flash disc and then the rest will be spinning disc. So there is a lot of nice options here. It is nice that you can mix and match which gives you a lot of flexibility here. Again this is based off of VMware, VSan so it is a VMware only option which is 80% of the market is running VMware so we feel it is a good fit for the majority of our customers. Next slide please. So here is just a quick slide to show the differences between the nodes. The top node is your 4 nodes in 1-2 node appliance and you can see the differences there. They all include a different offerings for data replication, data protection, and cloud services. We will delve a little deeper into each one. As you can see there is a lot of flexibility with this which is what we believe is a good thing about this is that a lot of hyper converge out there you are kind of tied down with a specific node types. Here with the Dell Emc you have a lot of flexibility. Next slide please. So here again this is just showing what you can do with each node. Maximum capacity per node. So as you can see the G series that is 4 nodes. So you would have a total of 80 terabytes raw and you can get anywhere from 40 terabytes depending on what type of protection you chose and so you just see this next slide just to show the different offerings that they have memory, CPU, networking things like that. Next slide. So again this kind of sums it up again in a nice way, lots of different offerings. I mean you have different Ram, processor storage, networking, GPUs again I mention for if you were doing VDI. This is something that we really think is a differentiator with VxRail offering. That we really believe. It is based now with Dell Emc off of leading edge power edge technology and I am actually at Dell Emc world and they just announced their latest power edge 14th generation server which will be getting rolled into the offerings with VxRail. So very we really believe it is a go to market hyper converge. Next slide please. So what actually is VxRail? VxRail was created jointly by Emc and VMware. It is powered by VMware. It has Vsan, Vcenter, Vrealize everything that most people are familiar with. It is primarily managed through Vcenter so you don’t have to learn 10 different new technologies or anything. It is very simple, easy to expand, you can add nodes in less than 5 minutes. You will have it up and running in less than 30 minutes to start. Deployment and support there is a VxRail manager that was built jointly by Emc and VMware. This allows you to deploy, it is a one stop shop for everything. So when you want to upgrade from Vsphere 6 to 6.1 you don’t have to worry about if I upgrade am I going to break my networking card or if I upgrade firmware in my disc is something going to break. This is a one package deal. You download it and it is going to upgrade your hardware and your software environment with one click of the button, obviously nondisruptive because you will utilize VMware utilities in HA and Vmotion. So it is a very nice quick easy way and you are getting a validated package that has been tested in the Dell Emc’s labs, you are not jumping in blind. Also the VxRail manager ties into both hardware and software for trouble shooting. So you don’t have to go to multiple windows to see if you are looking for performance. You can go to one window all the way from hardware through to the software. I mentioned it includes data protection options. You have recover point for VM’s. You get pretty much 5 licenses for that per node and obviously you can purchase additional nodes licenses if you need them. Recover point is a A sync or synchronize replication both local and remote and we will delve a little bit into that more and cloud array is it will attach to pretty much any cloud offering out there. If you have amazon, google, azure whatever you have out there it will allow you to tier your workloads to the cloud. Vsphere replication obviously that comes standard with Vsphere that is where you maybe would be replicating your tier 2 apps via replication and tier 1 via recover point and Vserve data protection for backup on recovery. That is what is kind of inside the VxRail and that is included no matter what node you buy. Next slide. So as I mentioned real quick, VxRail manager was jointly created by Emc and VMware. It allows you to upgrade the whole box, the whole unit. It allows you to when you add a new, when you connect a new box and a little thing pops up you click it and in 5 minutes a new node is in your VMware cluster and ready to use. You can also if you choose you can provision, you can create templates and provision VM’s through here with one click it will build it normally. Obviously you can still do everything through Vcenter, which most people do but it is nice to have some other options out there. Obviously as a performance management all the way through which is really nice, a nice click and clean window. Another thing that is nice is if you have an issue you don’t have to call VMware for one thing, Emc for something else. You call one number and they handle the whole support. They will get who they need. They will get who they want, who they need to talk too correctly, quickly, and efficiently. Next slide. So VxRail data protection, this is for backups. It is powered by and fronted by Emc’s Avamar. So it does D-duplication so you can obviously your backup window is reduced greatly because of this. It comes standard with an 8 terabyte capacity for backups. That can be expanded if you need to. This is pretty quick, obviously if you have a preferred backup that you are using something like beam or networker you can obviously continue to use whatever you like. This is just an offering. This is just something that is included in VxRail if you chose to use it. Next slide. So this is talking about recover point. I didn’t bring it up. So you get 5 VM license per node and this is every it is even Asynchronous it is as close to synchronous as you can get. Basically it is a splitter base so every time a write goes to the disc that write gets split. One sent to the disc, one sent to your replication, via that can be local or DR it is all in plenty of time and based on how big your journals are you can fail or test a point in time as far back as you need. It is a very nice utility. It can set up inside the GUI to change IPs for you. Obviously if you are replicating to a DR site that you need different IPs it will handle that for you. Push button very easy, no major scripts that you have to use. It is simple to set up and simple to use. Next slide. Also that is in a cloud array. So a cloud array basically does, it enables you to connect to, you get a VM locally that caches all the data and it D-dups, compresses, and it also encrypts all of your data to the cloud and this doesn’t matter what cloud you use. Like I said you could be using AWS, VMware, Google it will send that out there or it can be sending to a local or private cloud that you have. Very efficient, very nice, and again it is all encrypted so you don’t have to worry about, you know security is included in there. So a very nice option that you have to send your lower tier VM’s to the cloud and save space locally. Next slide please. So a quick comparison between VxRail cost and AWS. This is based off of a 650 VM’s it would be split across 7 VxRail nodes compared to a few different options from AWS. The highest cost offering for AWS would be on demand when you are just buying as you need and then the next one is where you commit to a year and then the next two cheaper ones from AWS are where you commit, you prepurchase 1 year or 3 years but even that 3 year offering from AWS is over twice the cost of what VxRail would be. This is what we are seeing a lot of with hyper converged is it is allowing you to keep your hardware on site instead of going to the cloud or most people are looking at a hybrid cloud. So you have your onsite annual cloud but the nice thing with hyper converge is that small footprint you don’t have to, small footprint you save power, cooling, things like that and efficiency simple management you know it is a very we believe we are going to be seeing more people choosing to keep at least their tier 1 and part of the tier 2 applications on prem and only sending their lower tier or DR to the cloud and if anybody would like I do have, I can send you a link to the white paper that goes more in depth about this study. So next slide please. Ok so now we are going to kind of change gears and talk about VxRack. VxRack is very again it could start small but it can grow massively. It is true scale out hardware and the great thing about this and I will probably go over this a lot, it comes with top of the rack switches. Cisco switches 9k and 3k switches depending on how many nodes you have which is something that most offerings do not. Most offerings you buy the appliance and then you have to be you are on hook for your networking and as you grow you can outgrow your network. You think everything is fine but your networking gets unmanaged and pretty soon you are seeing performance issues because you have grown past your networking capabilities. That is not an option with VxRack because when you buy it there you are getting a guarantee that the network is coming along with it. Every rack has networking included and this is a purpose built. So if you get VMware or red hat on this it will be built on site, configured on site all the way through the OS dropped on site, connected up, and you are ready to go in no time. So it is very nice. We will go over this, there are 2 different offerings. Next slide. So the two different offerings that they have are SDDC or flex. SDDC is based off of VMware, VMware, VSan. So it is 100% VMware. This can scale up to right now about 200 nodes and that will be expanding but VSan limitation is 64 nodes per cluster but you can have about 200 total nodes you just have different clusters. You might have a cluster for PDI and a cluster for regular infrastructure. The other offering is VxRack flex. This is based off of Emc’s scale IO and this enables you multiprocessor or multi hypervisor, multi OS which is a big rarity in the hyper converged world. Most are only hypervisor based. You can actually load windows, Linux, whatever you want on top of this. I am going to focus most on the flex. These SVC is very similar to VX layout it is just a bigger scale. There are some other nice features in there also. I am going to focus mostly on the flex today. Next slide. So what is actually inside of a VxRack? So hardware again Dell Emc PowerEdge servers. You have a 2 year or a 1 year offering. Your cisco switches, 9K-3K switches and a VxRack controller that controls, that is where your management is going to be and everything for that. Software is Dell Emc scale IO software. This pools all the storage. You get to pick and choose how you want to pool it. You can have all flash, hybrid, all spinning well you need some flash, hybrid or all flash and you can mix and match and move discs from one pool to another online fairly rapidly. Again you have your choice of hypervisor. If you chose VMware, Vsphere or red hat that will be preinstalled at the factory and ready to go. So you will give them your IP information and all that stuff it will be preinstalled. If you want to put Hyper-V, windows, Linux, KVM anything else they will configure everything up to bare metal and then you would as a customer would install that OS still 100% supported through of course and that may be changing over time. They may also start preintegrating Hyper-V in the other offerings. You have some different management support tools, vision, and scale IO Gui and of course everything plugs and plays into VMware Vcenter. There is a plugin for everything. So you are going to be spending most of your time in VMware Vcenter. Next slide please. So VxFlex is fully integrated. You can start small and grow extremely large. It delivers true scale out capability and true IOs that really believe no other offering can match. There are customers out there with fairly large 2-300-400 nodes that are pushing over 35 million IOPs with these. So it is very fast, very quick, very nice offering. Next slide. So again this shows it is for any application traditional, modern or cloud with any OS, hypervisor or media. So OS you have your Linux’s, your windows, hypervisors out there your cloud and your media both spinning discs, flash, and cards PCI slot cards and again you can go on your oracle, your exchange, your sequel server, doctor whatever you are looking to run you can run on this and the nice thing is you have options. You can have both your windows and VMware sharing the same disc so you have some tier 1, tier 2 discs or you can isolate pools to specific workloads. Very nice very efficient and very flexible to move that is why it is called flex. Next slide. So again one of the big features is the top of the rack switching which is not included fully in any other offering out there today and the main reason they want to do this is they want to make sure that as you grow you are not outgrowing your network and again this is one if you have any issue, you need anything it is one call, one phone number to call and they will work with cisco, Emc, Dell Emc or VMware behind the curtains. So it is very efficient in the top of the rack switching we really believe is a differentiator out there that really stands out for this offering. Next slide please. So again as you grow the top of the rack switching you have 40 gig links between each rack and then you have 10 gig from the nodes to the switches. Very easy, very quick to grow and these nodes you have again you can have storage heavy nodes. You can have nodes that are 100% storage and you can have nodes that are right now they don’t have compute only but you can still get compute heavy nodes but they will be coming out with compute only nodes also. So you can have massive storage space. So if you need to add a lot of storage for backup, archiving or whatever you can do that in here and share that storage across all of your different OS’s. Next slide. So this just goes over the support. Like I mentioned it is one number to call, one website. Once you get ahold of them they will handle everything behind there. You don’t have to worry about getting VMware and Emc on the line. They will take care of that for you. Very efficient, very nice, one probe to choke for this. It is a very nice offering and it all ties in. same thing with upgrades. Test it, you are not reinventing the wheel. You know when you go to upgrade you are getting a tested, validated upgrade pass. Next slide. VxRack management again you have there is vision, intelligence, this is standard with the VC previously with VC utilize to manage everything. This can manage your whole VX rack. You can also tie in VxRail into this if you were had a data center and then a remote robo officing and obviously VMware, Vcenter to manage it or if you are running Hyper-V Microsoft offerings and hten you have a Dell Emc scale IO Gui is also really nice it will show you how much IO you are getting currently. It allows you like I said to move if you need to move some flash disc from one pool to another you can do it online rather efficiently and fairly quickly. Next slide. Ok so that is the end of the presentation. If we do unfortunately I don’t have a demo today but if anybody would like to see a demo we can set that up with Dell Emc to go over. If there are any questions we can…
Rachel: Thank you John. We do have a few questions today. The first is can you present external storage to a VxRail?
John: You can. It is basically you can present the via NFS shares external storage to VxRail so that allows you if you still have a storage array that you want to tie into the environment also if you want for migrations from old to new you can present via NFS.
Rachel: Ok thank you. The next question is, can you use your existing switches with the VxRack?
John: The question there is, no. the simple answer is no and that is mainly because they want to make sure that you have the correct networking performance wise. They want to know that everything is 100% supported. There are scale IO other offerings out there for scale IO. There is scale IO ready nodes. So if you did just invest in brand new networking and switches you can obviously go with the scale IO ready node and utilize your own networking but if it is a VxRack it will include the networking and that is basically to make sure they know that you are going to have correct performance.
Rachel: Ok thank you. And our last question is, when would you go with a VxRail or a VxRack?
John: So your VxRail is typically your smallest size. Obviously they are all VMware, 100% VMware that is a great play for you. VxRack is typically your data center replacement and obviously if you are going to grow large and you want to run multiple hypervisors or multiple OS’s that is a big play when you would go to VxRack.
Rachel: Ok and we actually have another question that just came in. Can you present VxRack storage to VMware nodes via for example, NFS?
John: Can you repeat that?
Rachel: Yeah. It says can you present VxRack storage to it says none, I don’t know VxRack, VMware nodes? So I am not sure.
John: Once inside VxRack the storage inside VxRack can be presented to any OS but it has got to stay inside of, you can’t present the VxRack storage to a nonVxRack node. Of course you can do shares. You can create a share and share that out to another. So you can create a Linux share or a windows share and share that out to whatever you want but you can’t present if you have VxRack the storage in there natively via scale IO or VMware or Vsan has to be inside the nodes but if you want to create a share and present that out to some nonVxRack servers you absolutely can do that.
Rachel: Ok. Thank you. That will do it for the questions and thank you everybody. Thank you John, thank you everybody for joining our WebEx today.
