what would be recommended enterprise grade switch to play with?

Hello My current setup is 45 laptops and 6 servers connected to 2 48 gigabit port netgear managed switch with Cat6 cables in Gigabit full duplex mode, main GS752TPS and secondary GS748T. both switches are linked at this point with 4 ports LAG configured. all of the servers also have ports teamed and LAG configured. all of those laptops constantly sharing files between file server and rarely with each other, so in general use I don't run in to any serious slow downs with all of them running, but if I start to transfer lot's of files over the network, like few TBs, it seriously slows downs network. so time has come to add another switch since I have few ports left not used and was thinking what would be a better update in a heavy network environment. My plan is to get very high bandwidth switch that gonna have only servers connected to it to handle only there heavy networking since they are the ones who usually do lots of file transfer with each other and than linked to other switches so they all are on the same network. or is there any better configuration possible to achieve better network performance? any suggestions are welcomed. thanks

I guess I have to call them again. thanks

I sow log of the controller and nothing strange battery charge events and something like that, just green light no warning or errors, even dell tech support remotely troubleshooted other day and nothing. I'm using Dell Perk H800 hardware raid 10. I did updated bios and firmware of controller too. that worries me a lot. could be controllers fault?

@leadeater Hi I'm not really limited with budget I can have 10-25K spent if needed but I want to make sure I'm spending it right and it's going to do what our business needs. so I'm taking consultations form few different company's (one of them are Dell and HP) abut my project so let's see what they are going to suggest and now I have some idea what I need to hear from them thanks to you. btw something of the topic my server acted strange I had to restart few times and it took more than hr to restart each time when DAS was connected but when disconnected boots up in a few min. I suspected that DAS disks become foreign during reboot or shutdown, when I checked with diskpart before booting to OS it was foreign, so long boot time could be explained because it was importing foreign disks, but why would they become foreign? any ideas? thanks

oh woow that's lot of info to absorb... I have to read again to understand :-) thanks

Hello everyone! thanks for your advice's. the reason I don't want to use shared storage for both servers is because I have irreplaceable medical images that needs bulletproof or close to that data backup, so if something happens to that shared NAS for both servers it's game over, restoring all that images from RAW data that is stored somewhere else will take 4-6 months. so that's why I figured to have 2 separate servers with it's dedicated storage, also I think it's faster to access data from DAS than FC NAS, isn't it? since that data is constantly being accessed 24/7 and added more all the time by my opinion DAS makes more sense. pls correct me if I'm wrong. I'm not interested with HA, I need more like manual or some automation in case of failure to redirect traffic to second server. and I forgot to mention it's not file server I have that separately, this is more like web server with patient medical images for Dr's and medical personnel to access. as of OS I need to mirror somehow both host and virtual OS since both running critical services and apps, so in shortest time could be launched from second server, and for that having both OS's virtualized and having images synced seems to me very practical and efficient? again those are my ideas from my not so big experience in this matter, thanks

Hello everyone! so title pretty much says what is this post about and I have searched and couldn't find satisfying info for my project. I got Dell poweredge 720 with 2 MD1200 DAS in Raid 10 total of 90TB space, but at this point used 52TB so far. I'm adding about 20TB data in about every 6-8 month. I have host OS and one trough Hyper-V (Win 2012 Server both) both OS's located on PCIe SSD and mirroring trough windows on the second PCIe SSD. (I know it's not a good Idea, but had no choice when I was building it) so I have to clone entire server with both host and virtual OS and all the data on the second server and in case of hardware failure on one I can manually fire up and forward load on second Mirror server. well I have done similar project before by backing up virtual drives of hyper-v and firing up on second server, but not in such a big scale of DATA. I have few Ideas and I'd like to hear your opinions and experiences about this project. Ok mirroring OS: probably I have to create second virtual OS and move what's running on Host OS to it and sync virtual hard drives to mirror server with robocopy or something like GoodSync. Mirroring Data drive: again using robocopy or something like GoodSync. Syncing data trough: option a: Network trough 4 1Gigabit network ports that are in link aggregation and in full duplex mode. ( don't like this one since I think it will create lot of traffic in already busy network environment of 50 computers) Option b: adding another 4 port network adapter (dedicated) and moving data in between trough crossover cable connection. I don't know if I missed any details needed, I think I cover everything. I would be very grateful to read your feedback and experiences about this project. thanks
