The EMC-HP storage relationship is grinding closer to a complete halt. Late last month, Hewlett-Packard announced that its reseller arrangement with EMC will end on June 30. The announcement came only one month after HP said it would continue to resell EMC Symmetrix arrays despite introducing its own high-end array (InfoStor, June, p. 1). According to Marilyn Edling, general manager of HP?s Enterprise Storage Division, EMC did not like the arrangement and felt "uncomfortable" divulging future Sy

Since re-dedicating their efforts earlier this year, members of the Storage Networking Industry Association (SNIA) are continuing plans to develop SAN interoperability standards and to educate end users about the merits of storage networking.
Users are increasingly viewing RAID arrays as commodity devices, and are finding it more and more difficult to distinguish among the myriad offerings. As a result, vendors are trying to differentiate their products with software.
With the release of Virtual Storage Manager (VSM) 2.0, StorageTek says it has overcome installation issues that have plagued the software since its December announcement. VSM is an integrated disk and software solution that maximizes total storage capacity by making more efficient use of tape cartridges.

Before the introduction of the CD, it would have been hard to state that optical storage had taken the mass storage industry by storm. Conflicting MO formats were the rule, rather than the exception...a situation that foreshadowed the turbulence regarding DVD formats. Purchases were delayed as the IT community waited out the survivors of the conflict. But with the staggering success of the CD, and the undeniable popularity of CD-R, it is possible to identify optical technology as a storage strat
