LISA originally stood for "Large Installation System Administration," where "large" meant systems with more than a gigabyte of storage, or with more than 100 users. Some topics are still present at LISA, such as network management and uptime (reliability), but many others have been updated over the years. Hope to see you in Nashville!

There are two ways to take advantage of non-volatile storage (NVDIMM) for SQL Server (Direct access or Block Device storage.). Block storage is what you think of today as disk access. SQL works with the operating system to detect the non-volatile storage devices and leverage them for the tail of the log.

SQL Server will need to check all the existing values to ensure no nulls are present. When compressed, fixed-length string columns do not store trailing blanks, making them just as efficient as variable-length string columns from a storage point of view. It will then physically rewrite every row of the table. Acknowledgements.

During the ten week course, students implement four different assignments: an exactly-once RPC protocol; a primary-backup system; Paxos; and a scalable, transactional key-value storage system. 175 undergraduates a year currently go through this course. Prunes are predicates telling the model checker which states not to expand.
