There have been many questions raised recently about which of Sun's products will have a life after Oracle.

The need to develop data archiving capabilities is a challenge that every enterprise faces these days for any or all of several needs: whether to accommodate explosive data growth; to respond to the pressure to meet promised service levels and backup windows for users; to provide archive data retention and retrieval requirements; and to better manage rising energy costs. Dean Halbeisen's Sun BluePrints Online paper "Sun Systems for Sun StorageTek Enterprise Backup Software" details the openly architected, intelligent and massively scalable general purpose archive solutions Sun is developing to assist enterprise users in meeting these challenges.
In September 2008, medical products maker ResMed decided to replace 160 PCs with Sun Ray 2 Thin Clients, and purchased two SPARC Enterprise T2000 Servers with chip multithreading, and four Sun Fire X4440 Servers to support its new solution. According to ResMed, IT productivity has increased by the equivalent of two additional IT staff, and the company has saved about $267,850. The Sun solution also increased security and substantially reduced energy costs as well as the noise-level.
The Sun BluePrints article "LDoms I/O Best Practices - Storage Availability with Logical Domains" by Peter A. Wilson discusses the approaches and trade-offs for configuring highly available paths from Sun Logical Domains (LDoms) guest domains to storage. Topics include I/O availability, multipath I/O with Solaris OS MPxIO, multipath I/O with virtual I/O failover, virtual I/O failover and network file storage, and multipath I/O to network file storage with virtual I/O failover.
