I have a photo studio that has an existing network that I call JBOM (Just a Bunch of Macs) in a star config around a gigabit switch. I tried some sub-$1000 NAS boxes but too slow and other issues like smb vs afp caused problems...so....I have purchased a 2010 MacMini Server with SLS and will be testing it out soon using the FW800 port to daisychain at least two 15TB R5 boxes for primary and archive storage needs. We have about 10 Macs of various vintages producing about 50-100GB's new data per day. (everything from shooting workstations to post-proc stations to admin...etc.) My question is what mods, if any, do you think will best improve the Mini in its role as a server? It will be a file server first and foremost and everything else a distant 2nd and 3rd priority. It will Host Retrospect for backups to on and offsite HD's but thats about the only non-server software that may sit on it. Could care less about running Photoslop or ID or DW or LR on it, I have MacPro's for that. File ServerFile ServerFile ServerFile Server! what will be best for that? With that in mind, will its abilities be improved most by: A. Increase RAM to 8GB from 4GB? B. Replace internal hard drive(s) with SSD drives? C. Install one or possibly two eSATA ports? D. Install one extra gigabit ethernet port for possible iSCSI? E. Anything else I didnt list here?
