  • SAN SOLUTIONS

  • Storage Area Networks (SANs) are gaining acceptance at an astounding rate as a solution for organizations that are experiencing explosive storage growth. A SAN consolidates your storage for easier storage management and better use of storage resources. A SAN will allow for scalability as you add more hosts and more storage and minimizes the downtime associated with those activities compared with a Direct Attached Storage (DAS) environment. A SAN environment can increase backup performance by offloading traffic from your IP network and freeing your host's processor from packaging the backup data for IP transmission. You can also take advantage of a SAN's any-to-any connectivity to implement redundancy and disaster tolerance both locally and across long distances.

    Because SANs are similar to other network technologies you've probably worked with, you can draw some comparisons to bring yourself up to speed on SAN components and how they operate together. The various pieces fall into three categories: interconnecting devices, storage devices, and hosts. Interconnecting devices include hubs, switches, bridges, and routers. Storage devices range from Just a Bunch of Disks (JBOD) to highly redundant and intelligent RAID enclosures that scale to meet the needs of the largest enterprises. Hosts are the computers that attach to the SAN through a host bus adapter (HBA), which is akin to a NIC in a typical data network.

    Deploying Fibre Channel switches in a SAN offers the same performance and manageability benefits as deploying switches in an Ethernet environment. Fibre Channel bridges and routers perform functions similar to their data-networking counterparts, enabling Fibre Channel connectivity to SCSI, Asynchronous Transfer Mode (ATM), and even Ethernet across long distances.

    A wide range of SAN storage choices are available to fit different applications. On the low end, JBODs provide the most raw storage for the least amount of money. You can use native or third-party volume-management tools to implement software RAID on the disks in the JBOD enclosure, but Fibre Channel RAID enclosures offer more robust solutions along with better availability and manageability. Typical RAID enclosures include redundant core components and built-in management facilities.

    Each host uses an HBA to connect to the storage devices in a SAN. Technically, legacy SCSI controllers are HBAs that connect the host to a SCSI device; HBAs on a SAN perform the same service in letting a host attach to Fibre Channel devices. HBAs process block-level I/O without relying on the host's CPU, thus minimizing the CPU and bus utilization I/O burden on the host. You can install multiple HBAs in a host to achieve redundant data paths and improve availability. In "SAN Solutions," which appeared in the September 2002 issue of Windows & .NET Magazine, I look at some SAN components and implement them as a fictional company, Datahogs, to show how a SAN can benefit your organization.

    2. NEWS AND VIEWS
    (contributed by Keith Furman, [email protected])

  • HP CONTINUES STORAGE PARTNERSHIPS WITH NEW HITACHI AGREEMENT

  • Following similar deals this summer with IBM and EMC, Hewlett-Packard (HP) has announced an agreement with Hitachi: The two companies will cross-license storage APIs that will enable their storage-management software to manage each other's products. The agreement will add support to HP's OpenView Storage Area Management (SAN) software to let it manage Hitachi Freedom Storage Lightning 9900 and 9900 V Series and Thunder 9200 Series storage arrays. Hitachi's HiCommand Management framework will gain support to manage the HP StorageWorks XP and VA disk arrays, HP StorageWorks Enterprise Virtual Array (EVA), and HP StorageWorks Enterprise Modular Array (EMA) storage systems.

    According to the two companies, the agreement is a step toward the standards-based storage-management initiatives currently evolving in the industry. According to Mark Sorenson, vice president, Storage Software Division, HP Network Storage Solutions, "The knowledge HP is gaining through integrating API technologies from Hitachi, Ltd. and other companies into a common software management platform will be used to assist the industry in making Bluefin and \[Storage management Initiative\] SMI a reality."

  • MICROSOFT RELEASES STORAGE SOFTWARE, BUYS STORAGE SECURITY COMPANY

  • Microsoft announced new Multipath I/O technology, which the company will include in future versions of Windows and many storage vendors will support. Multipath I/O enables systems to access storage systems through multiple paths, such as multiple Fibre Channel connections. Multipath I/O will let storage vendors use Windows to deliver solutions with fault tolerance and load balancing. EMC currently makes a similar product called PowerPath.

    Microsoft will support the technology in Windows 2000 Server and the upcoming Windows .NET Server (Win.NET Server) 2003. The following companies will also support Multipath I/O: 3PARdata, Agilent Technologies, Egenera, EMC, Emulex, Fujitsu, Hewlett-Packard (HP), Hitachi, LSI Logic Storage Systems, Maranti Networks, NEC, Network Appliance (NetApp), oPoet, PolyServe, QLogic, Rhapsody Networks, Seagate Technology, Stratus Technologies Bermuda, Unisys, VERITAS Software, Vicom Systems, and XIOtech.

    Microsoft also announced the acquisition of XDegrees, a security software developer. The Mountain View, California, company develops products to secure data access across computer and storage systems installed in large companies. Microsoft plans to use XDegrees' technology in future file systems to help strengthen Windows' support for advanced data storage.
