The "CassandraHardware" page has been changed by JonathanEllis. http://wiki.apache.org/cassandra/CassandraHardware?action=diff&rev1=1&rev2=2 -------------------------------------------------- The most recently written data resides in memory tables (aka [[MemtableThresholds|memtables]]), but older data that has been flushed to disk can be kept in the OS's file-system cache. In other words, ''the more memory, the better'', with 1GB being the minimum recommended. === CPU === - Many workloads will actually be CPU-bound in Cassandra before being memory-bound. Cassandra is highly concurrent and will make good use of however many cores you can give it. + Many workloads will actually be CPU-bound in Cassandra before being memory-bound. Cassandra is highly concurrent and will make good use of however many cores you can give it. For high-end clusters, quad- or 8-core boxes are good. If you're running on virtualized machines, consider using a provider such as Rackspace Cloud Servers that allows CPU bursting. === Disk ===
