    The more nodes you have in a single Nutanix cluster the faster the rebuild time will be. You can also set the replication factor to 2 or more with the latest version, you could do it on 3.x but you needed engineering to assist.

    I doubt the 2000 nodes are in a single Nutanix cluster, but I am happy to be proved wrong, its all learning. With vmware limited to 32 and Hyper-V limited to 64, i know I wouldnt deploy a 2000 node single cluster.

    Not a Nutanix employee, I'm a hyperconvergence specialist. Whoever told you buying Nutanix was about making it cheaper was only telling you part of the story. Yes, compared to VCE it certainly is, and unlike VCE vBlock is actually converged and not just packaged, but the whole point about Nutanix is scalability - they call it web-scale.

    Google, Facebook and Amazon do not run their businesses on SANs, but thousands of converged compute/storage nodes. One of the architects of the Google distributed file system also wrote the Nutanix version - NDFS.

    The idea is you can start small and scale in a linear way, and as you scale performance stays the same (grows in the same linear way) and it is just as easy to manage. This is not the case with a SAN - you reach performance limits and then can expand to the controller limit, at which point a forklift upgrade is likely. In the case of the 2000 node installation they started with a proof of concept and then just kept growing by adding blocks as they scaled out the system. NO storage planning was needed (no LUNS!) and they haven't hit a brick wall on storage performance where they had to start again with better models.

    Also as you rightly point out you need a storage specialist because at scale a SAN is a nightmare to manage and maintain.

    One caveat I would stress is having a good network team in there and if you are going to scale big time make sure your leaf/spine network is up to scratch with a 40G core and 10G TOR switches, because the nodes do have to communicate even though they don't drag all the data from remote storage to the calling VM as happens with a SAN.

    If you really want to get into the tech then this is a mine of information on Nutanix - make sure you have a big coffee on the go though it's not short ;) http://stevenpoitras.com/the-nutanix-bible/

    No, the 2000 isn't in a single cluster, there are a multitude of availability domains to make sure nodes going out don't down the whole thing. It's also a KVM implementation.

    The rest of your post was excellent, but not as good as web-scale.

    What advantages does this have over running VCE vBlock, besides price?

    I make no excuses for marketing (I did say "they" after all) :rolleyes:

    I am going to be very lazy I'm afraid and point you at another blog because when you see the number of reasons and amount of text you wouldn't want it here in this thread ;)

    10 reasons why

    Your my new internet friend.

    Sorry FiSHy you have been replaced by a better variety (less smell).... meanwhile i shall end thread derail here.

    That's disappointing, I was hoping to find out how web-scale compares to cloud-scale.

    Is one linear and the other exponential?
    Is log-log graph paper required to plot growth or is semi-log sufficient?
    Two many unanswered questions.

    Web-scale? pfft, that's old. I'm running the new <insertbuzzwordhere>-scale system and it's so much better than web-scale.

    It seems to be the latest buzzword instead of cloud to do a search and replace with. I wonder if they're smart enough to use something like "sed" and point it at the marketing directory....

    That said, Nutanix does appear to be a good product from a technical perspective. I'm running something fairly similar (for a different market space) and it's quite effective.

    I think you mean "nu-scale"

    Appreciate the reply.

    Hardware vendors have the option to integration SMB3 VSS support natively, I guess that's where I was going, does Nutanix support that integration.

    I don't really know if Nutanix is using a MS OS to host the SMB share or some sort of samba implementation. Assume the latter. In either case it wasn't working. All good now though - handed this one up the chain :)

    Nice information, thank you. And good points on the ease of scaling. So to be fair, what negatives are there of going Nutanix, or what general scenarios does it either not make financial or technical sense?

    1. Small implementations. They do have the 1000 range of appliances but these are aimed at branch offices of Enterprises rather than SMEs. In the SME space you are better with vSAN, or Datacore, etc. A lot would say likewise for bigger systems but you need to take into account the Enterprise features of Nutanix, and the likelihood of scale - which you wouldn't be likely to get with an SME.

    2. Large DB Servers. This all depends on working set size, but if you have 2TB SQL Server that regularly trolls it's whole DB then the working set size will be over the SSD limit of a node in Nutanix and performance will tank. Having said that Michael Webster (@nzvcdx001) has dome some work with monster Oracle VMs on Nutanix, so I wouldn't write it off completely.

    3. You do pay a premium for the hardware. This is contentious but I addressed this in a blog recently: Millennia Blog

    It's not a panacea for your IT woes, it sits alongside a lot of other solutions and it's up to you to determine the best fit.

    ouch - fair enough....perhaps some people may like to talk to people who've implemented the Nutanix tech in their DCs *in person* and not just over a forum thread....plus you know - free drinks...? :p

    Anyway here's a link to blogs etc for more info too (The Nutanix Index) : http://myvirtualcloud.net/?page_id=5770

    Remember The Nutanix Bible is also a fantastic technical resource and is updated constantly: http://stevenpoitras.com/the-nutanix-bible

    Replies to a post pointing out how nobody likes marketing spam, with more (slightly technical) marketing spam.

    It's a bold move Cotton, Let's see if it pays off.

    I love that we get vendors who come in here to actually talk openly with our guys about their technologies - I really do. I know alot of the guys here appreciate the chance to speak to the right people about new technologies - but when the forum becomes a marketing platform for vendors - thats when the line gets crossed for what this place is all about :)

    I agree, there is nothing wrong with coming into threads about your product and clarifying things that have been said, and actually adding value to the community, but I'm not a fan of posts that are soley driven by marketing. By all means, have link to your product/companies blog in your signature.

    On related Nutanix news - Dell will be selling them in the very near future.
