DELL PowerVault MD3200i/MD3220i Technical Guide Book4Advantages of iSCSI technology include:• Expansive ReachAs a routable transport with no distance limitations, IP SANs can be located almostanywhere. The reach of a SAN throughout the organization is most often limited by thedistance restriction of the interface. iSCSI removes these distance limitations to limitlessboundaries and extends its scope well beyond the corporate data center to remote locationsas well.• Minimal InvestmentiSCSI allows businesses to control their storage expenses without completely retro-fittingtheir existing network. iSCSI creates IP-based SANs which allows organizations to capitalizeon components of their existing IP infrastructure by delivering block based storage across anIP network. Organizations do not have to invest in a new storage-only infrastructure, such aswith FC which can be costly• Enormous Knowledge and Experience BaseiSCSI allows almost all organizations to capitalize on existing IT skill sets to create IP-basedSANs as in-house networking expertise is standard throughout most companies today. Anend user does not have to learn a new networking protocol and go through extensive andsometimes expensive training, such as with FC. As a mature, well-understood technologywith a broad range of proven management tools, iSCSI is easily deployed by administratorswith LAN experience.6Gb Serial Attached SCSI (SAS 2.0)SAS provides a scalable point-to-point topology capable of addressing storage connectivity at manylevels. As SAS enters its second generation, the standard is evolving to enable better bandwidthutilization, easier management mechanisms, and network robustness.6Gb/s SAS 2.0 not only doubles the current data transfer rate it provides standardized zoning, self-discovery, and self-configuration methods to expanders. This makes larger and more complextopologies easier than ever to implement.Key features of SAS 2.0• 6Gb/s SAS Signaling – doubles the transfer rate from 3Gb/s to 6Gb/s• DFE (Decision Feedback Equalization) – increases cable limit to 10m ( 2 – 4 is typical)• Supports SAS mini connectors (SFF-8088 and SFF-8087)• SSC (Spread Spectrum Clocking ) – ease of design implementation – reduce peak amplitude ofradiated emissions• Supports SED (Self-Encrypting Drive) with Instant Secure Erase• Delivers 2 nd generation SAS Discovery• Standardized Zoning• Expanded to 256 devices• Discovery executed by SAS Expanders• Reduces time to discover large topologies
