A Practical Hardware Sizing Guide for Sybase IQ

that are undergoing constant data refreshes, however, it is quite possible to architect a system
where there are two or more write nodes whose sole responsibility is to handle data changes
while N number of other nodes are defined as query, or read, nodes to handle all read operations
in the database.
Other Features of Note
Partitioning was also introduced in IQ 15. From a sizing perspective, however, this does not
come in to the equation other than how it pertains to multiple dbspaces and partition placement.
In order to handle tiered storage, partitioning, and object placement on disk, Sybase IQ 15
introduced multiple dbspaces. The DBA can create any number of dbspaces to hold data objects.
These objects include tables, columns, indexes, and partitions. The storage sizing guidelines
contained in this document cover sizing of an individual dbspace, not all dbspaces for the
database.
