The Sun Cluster 2.0 product was released in October 1997. This release began to merge the features offered by SPARCcluster PDB 1.2 and Solstice HA 1.3 software. This effort took 18 months, culminating in the Sun Cluster 2.2 release.
The initial Sun Cluster 2.0 release supported the following features:
Veritas Volume Manager (VxVM) only
Veritas File System (VxFS) was required to provide file system logging because Solstice DiskSuite was not supported
Solaris 2.5.1 support, with Solaris 2.6 support following in December of that year
Support for Ultra Enterprise 1, 2, 3000, 4000, 5000, 6000, and 10000 and SPARCcenter 1000E and 2000E
Up to four nodes in an N+1 storage topology
Agent support for Oracle 8i OPS parallel RDBM, Informix XPS, Sybase MPP, Netscape (news, web, and mail), DNS, and NFS
Support for Sun RSM Array™ 2000 and Sun Enterprise Network Array™ A5000 (as it was then known, before the StorEdge rebranding)
An HA-API for writing custom agents
Sun Cluster 2.1 was released in April 1998 and added support for the following:
Solaris 2.6 operating environment
Two-way initiated Sun StorEdge A3000 array
A scalable storage topology supporting up to four nodes, using the Sun StorEdge A5000

The first release of Sun Cluster 2.2, in April 1999, completed the planned merger and added support for:
Solaris 7 operating environment
The Netra t1120 and Netra t1125 servers
Sun Gigabit Ethernet as a public network
New HA agents for Tivoli, Lotus Notes, BEA Tuxedo, and Netscape Lightweight Directory Access Protocol (LDAP)
