Thanks to continued high demand for backup, management and replication technologies, storage software revenues grew 12.6 percent to $8.9 billion last year.
Those segments were responsible for pumping almost $1 billion into the storage software market, according to IDC's latest storage software report.
For the full year, EMC led the market with a 29.7 percent revenue share, followed by Symantec with 20.3 percent and IBM with 10.5 percent. Network Appliance and HP rounded out the top five with 6.6 percent and 6.5 percent, respectively.
The fourth quarter's growth was slightly less than the full year's rate, clocking in at 11.2 percent year-over-year growth to $2.4 billion.
For the fourth quarter, EMC led the market with a 29.2 percent revenue share. Thanks to its Veritas purchase, Symantec took the second position, with 19.7 percent. IBM was third in Q4 with an 11.5 percent share, followed by Network Appliance and HP, with 6.7 percent and 6.5 percent revenue share, respectively.
IBM notched a 32.6 percent year-over-year growth rate, outpacing all but number four NetApp's 41.2 percent growth rate. EMC grew at a 5.8 percent rate in the fourth quarter, Symantec at 4.4 percent, and HP grew 6.1 percent in the quarter.
For all of 2005, EMC grew at an 11.2 percent rate, Symantec grew 7.1 percent, IBM 26.8 percent, NetApp 45.4 percent, and HP 4.8 percent.
Backup, archive and storage resource management segments each grabbed about a third of the market in the fourth quarter.
Storage replication, in which stored or archived data is copied in real time as it moves across a storage area network (SAN), grew 21.7 percent year-over-year in the fourth quarter.
IDC analyst Rhoda Phillips said the success of these technologies is driven by customer requirements for protecting and securing information in an IT environment that may have several pieces of disparate equipment.
To corral the glut of e-mail and other forms of data, companies have been buying different tiers of storage to manage different files. These are typically part of so-called information lifecycle management (ILM) strategies for creating and disposing of data.
"This demand is in response to the growth of information and the impact of the requirements to have more information online with greater protection throughout the entire business cycle," Phillips said in a statement.
Storage hardware also enjoyed a fine year and Q4, according to IDC.
