Once again the meeting evolved into a round table discussion of popular system administration topics including RAID, backup choices and an explaination of network resource sharing with services like NIS, NFS and LDAP. Before it all got started Mark explained the status of the domain name registration and how individuals can donate if they wish. Also, Mike Szafranski had a couple of books and some older Linux CD's to give away. The discussion on RAID outlined the characteristics and benefits of the more popular RAID solutions, the basic RAID0 is only striping (drive combining) with no redundancy at all. RAID1 provides mirroring which gives redundancy protection to data. RAID5 is striping with parity, this allows data to be rebuilt if one of the drives goes defective. RAID10 or 01 provides the benefits of both RAID0 and RAID1 and it appears this type of mixing can provide for almost any requirement. It was also pointed out that RAID should only be used in read-only applications or with very light write requirements. The standard back up solution presented was tape. From 100Gig fast SCSI based LTO with auto loaders to DDS4 20 Gig single tape system seemed to span the current offerings. It was stressed that no system administrator should operate without a sound backup strategy. The network sharing services were presented with some discussion of their application and limitations. NIS (Network Information Service) is useful and allows for distribution of passwords and other admin data between multiple computers to provide for accounts and system access on multiple computers. NFS (Network File System) allows for the sharing of home and other directories among many computers. We also got into a variety of off topic discussions which were very interesting but don't bear repeating here! Actually the comment was made how those discussions would be handled in the minutes ... now you know! :-) That wrapped up the evening and thanks to Mark and all who attended and participated. 3) Next Meeting: Tue. May 14, 2002 - "Compiling a Kernel"
