Overview

Are you lacking a simple external direct attached or shared storage solution for your c-Class enclosures?

The HP StorageWorks 3Gb SAS BL Switch for HP BladeSystem c-Class enclosures is an integral part of an HP direct connect SAS storage solution, providing a straight forward architecture for external zoned direct attach as well as shared SAS storage. BladeSystem server administrators now have a simple in-rack SAS storage solution that’s ideal for growing capacity requirements—without the need to coordinate storage requirements with SAN administrators.

The SAS architecture combines a P700m Smart Array in each server, and 3Gb SAS BL switches connected to HP StorageWorks MDS600 or MSA2000sa SAS storage devices. The simplicity of SAS results in a very low cost per GB, enabling low cost zoned or shared SAS storage.

What’s New
  • The 3Gb/s SAS switch is enhanced with zoned direct attach capabilities.

    • Features and Benefits
    More external storage for c-Class enclosures
    • Offers flexibility for shared storage: Enables servers within the c-Class BladeSystem enclosure to share storage on an MSA2000sa, without the need for an external SAN infrastructure. Increases storage utilization, flexibility, and enables full virtualization without a SAN.
    • Also provides zoned DAS storage: Or use the flexible SAS architecture for cost-effective in-rack zoned storage using the MDS600. MDS600 drives are assigned to specific blade servers so they appear as local storage to that server.
    • New storage price/performance ratio: 3 Gb/s performance, without the infrastructure expense. Not all data requirements need the top performance and availability of a backend Fibre Channel SAN.
    Simplified management
    • Easy SAS connectivity with c-Class BladeSystem: Centralizes control and reduces storage management cost. Management tools and software included in the price.
    • Target-based management: Use the Virtual SAS Manager (VSM) 3Gb/s SAS BL switch to dynamically assign drives to each BladeSystem server, on the fly, without complex configuration or re-cabling.
    Highly available, cost-effective external storage
    • High availability and path failover: Redundant SAS switches are active, if one fails the second takes over the entire workload.
