Sources agree this is not as challenging as sending data over public lines, but nevertheless, it exceeds the distances for IP SANs so far.
According to Nishan, the project also showcased iSSCI technology working on a real network. Nishan says that to carry the demo's traffic, its IPS 3000 series storage switches were linked to switches from Cisco Systems Inc. (Nasdaq: CSCO) and Ciena Corp. (Nasdaq: CIEN) on Qwests nationwide IP network. Adaptec Inc. (Nasdaq: ADPT), Intel and Qlogic provided iSCSI server connectivity, Dell strumped up servers and storage devices, Veritas Software Corp. (Nasdaq: VRTS) provided back-up software, and IBM and HDS contributed Fibre Channel and IP storage gear.
"When planning for global deployments of storage systems, organizations need to trust that products from multiple IP storage vendors will work together, says Greg Lang, VP and general manager of Intel's networking group. The success of this first coast-to-coast transmission of I/O block data using Gigabit Ethernet and iSCSI over IP Networks shows the gains made by vendors in the area of interoperability.".
The network will continue to run for several weeks, while Nishan invites other storage players to take part. Still, it should be kept in mind that Nishan is not the only one building long distance IP SANs. Compaq claims it has built the worlds largest multi-vendor storage area network (SAN) by linking three separate SANs on three continents -- Australia, America and Europe -- and has done so using a combination of fibre and IP technology. (see Compaq Road Tests Global SAN).

To realize the benefits of cloud-native software, an application must actually be cloud-native—designed to run in the cloud, interacting with disaggregated cloud services, fully manageable as code—to deliver the expected benefits.
By combining resources and expertise, the AI-Enabled ICT Workforce Consortium will offer a blueprint for how industries can adapt to an AI-dominated future.
IT leaders should heed the guidance of cybersecurity insurance providers who think businesses should prioritize security education, incident preparedness, regular internal audits, and ongoing vulnerability scanning and patching.
