Server Requirements for Small Lync Implementation?

    Question

  • We are new to lync on premise and are trying to get an idea of the hardware requirements for a very small (tiny) Lync Server implementation. I've been playing with the Lync planning tool (very cool) but it seems to give the same hardware requirements (quad core, 12gb ram, ssd drives) for 1000 or 50 endpoints. ;-) I'm guessing that the requirements are note the sam--and in the same token, 25-50 user implementations are probably kind of rare. ;-)

    Our senario:
    -small, only 30 users
    -They want to IM, application share and multiparty video
    -Live Messenger federation
    -not using Lync as a pbx at all

    -There will be 5 of the 30 users outside the LAN

    I'm curious what suggestions the veterans have out there for the smb market? For this tiny senario is a Proliant ML1xx okay? with 4/8GB ram? what kind of processor?

    thanks!

  • Hi,

    As per your scenario I think ML 150 G6 or G7 with 8 GB of RAM is well enough for you also for edge server role you can use 4 GB RAM because you have just 5 users in place for using outside from your LAN, as per my experience I am using 8 GB on ML 150 G6 for 56 users at my office and performance is ok even I am not getting any troubles with the server.

    I hope this will help you, if further help needed kindly let us know.

    Regards.

  • Right now I run a virtual machine with 4 cpus, 8 GB of memory for my front end. On my edge I am just doing 4 CPU 4GB of memory.

    We are around 50 users.

  • Hi,

     

    I am using a HP polirant DL4G with 8 GB of RAM for 50 Users and i have the Edge server running the same hardware and the performance is quite good.

    so i think your hardware will meet your organisation requirements. go for it :)

     

    regards,

  • The planning tool gives you that requirement because that's the minimum requirement for an OCS Box based on Microsoft testing and those are based on probably a higher user density. The tool just follows these guideliness.

    It will run OK on a lesser system than proposed, but you might get troubles with support if your system does not meet minimum requirements and you're opening a ticket where you have performance issues. Can somebody clarify if running a system with below minimum specs for such a small number of users is a supported configuration at all by MS support?

  • Yes, microsoft is usually not unreasonable when it comes to that. They understand their specs are done for much larger deployments.

     

    However, if you start having performance issues, or audio/video quality issues, I wouldn't expect to get much help until you increase resources :)

    In general though, running on a smaller pool of resources for smaller deployments is completely supported, the solution is designed to scale up and down per the company requirements.

  • Just for any one following this thread:

    We installed a lab to test for SMB Lync implementations. We are using 2 HP Proliant Microservers (Athlon II Neo/like an Atom) with 1GB of RAM. (yes, that is correct. ;-) We have install Windows Server 2008 R2 Standard as the base O/S on each server. On the Lync server we have Lync Server 2010 Standard installed. I just want to report that it actually worked. ;-) Obviously not recommended but for someone that has minimal hardware for a lab. We also tested a 3 user audio, video and screen sharing conference and that seemed to work also.

    Once again, not for live usage but as a test it actually seems to work.

  • I haven't upgraded to Lync yet, but on our OCS 2007 R2 deployement, all servers are virtualized. The Front-end VM has 1.5GB of RAM, 2 virtual CPUs. The Edge server has the same setup. We have around 60 - 80 users that connect to it, most of the time internally. The CPUs on both machines are usually under 5%. The VM host also hosts 19 other VMs, and it's an older Proliant DL585 G2.

  • Sounds good.

    I'm going to deploy a brand new Edge Server for 150users. it will have 4 GB RAM and 3.0 GHz Dual core with RAID 1. Most of the user will be internal if needed then I've option to upgrade the RAM.

  • I am running Hyper-V with:

    Frontend: 6 gb ram, 4 vcpus

    Mediation: 6 gb ram, 4 vcpus

    AV conf: 4 gb ram, 2 vcpus

    Edge: 6 gb ram, 4 vcpus

    Exchange UM: 4 gb ram, 2 vcpus

    Will be starting off with roughly 35 users, full enterprise voice.  Will gradually scale to around 150, and possibly as many as 300 down the road.  All users will be connecting in via edge - internal use is terminal server only so lync on the terminal servers is locked down to im/presence/desktop sharing.

  • so you have 16 core cpu and loads of ram , i guess 32 gigs,?

    which phone system do you have at present, and how is the result with 35 user testing? I'd love to implement the same. are u based in usa?

  • We actually have two hyper-v servers running in a cluster, each with 96 GB of ram and two quad-core low voltage xeons 2.26ghz.  This way either one server could handle all VMs if one server were to fail (we have exchange, file server, dcs, etc).

    We only have 3 users live right now - the full 35 will go live in a couple of weeks; i'll let you know how it goes and what adjustments we make.  We are in the US and are replacing an old meridian pbx; i'm not sure of the details of the other pbxes that will be replaced in the future.
