Hi I have recently been approached by a SMB customer who has a small (11 users) network of OSX based machines with a very old mac mini server (i would expect is a first release). The use the apple sever for file sharing, directory services, mail etc. The company has a lot of data stored on the mac mini, are running out of space and complain how slow it is, they also complain that the mail/calendar/contacts services are flaky and problematic. They also complain about the speed of their VPN when working from home (which will be due to their limited upload speed). I am trying to come up with a solution for them but i mainly deal with Windows servers and networking for enterprise. I don't know a great deal about apple servers, however after doing research it looks very easy to set up etc, but also when doing research i find a lot of people online comment on the mail setup being flaky etc. I am wondering if people can give me advice on their experience with this type of set up. I'm finding it really hard to find much osx server info online, other than it being slated. Originally i was thinking of implementing cloud based email (they have outlook users) so thought of hosted exchange or office 365 rather than the mac mail server. Google apps (my usual favorite) is out of the window because there is no google apps sync tool for outlook on the mac, imap is cumbersome and clunky. I thought we could keep their original mac mini for directory services. Then i could use a Synology or QNAP NAS device for file shares, cloud backup but most importantly i could use the cloud file sync app for home workers. This would mean they would be accessing the sync'd files locally rather than accessing a server via the VPN. Obviously i could get a mac mini os x server, install a file syncing cloud app and do the same thing but the performance of the NAS should in theory outperform the mac mini. I also like the fact the NAS would have hot swap drive bays on the front. I have dealt with macs before but in terms of networking... snow leopard would have been my last dabble and even then it wasn't exactly great. My only reason now for shying away from OSX server is mainly due to reading raving reviews for synology and QNAP devices from mac users, and complaints regarding the OSX server. Thanks for any help and advice.
