HDS Launches Preemptive Strike: Page 2 of 2

Meanwhile, EMC is expected to adopt a switched-loop architecture in the Symm 6, with overall throughput increasing to up to 13 GByte/s, according to a research note issued by Merrill Lynch & Co. Inc. Hitachi claims its system's Hi-Star crossbar switch architecture can handle up to 15.9 GByte/s of aggregate bandwidth, although the company notes IBM Corp. (NYSE: IBM), effectively doubling the system's total raw capacity to 148 Tbytes (see Hitachi Launches Disk Company).

  • Increased connectivity: The system now provides up to 64 2-Gbit/s Fibre Channel connections and 32 Ficon channels. Previously, the Lightning 9900 V provided a maximum of 32 FC ports.

    HDS also tried to make it seem as if it had enhanced the Lightning 9900 V's Virtual Storage Ports (VSPs) feature, which allow up to 128 hosts to access each physical Fibre Channel port -- but this turns out to be untrue.

    In an interview Wednesday, Scott Genereux, HDS's VP of global marketing and business development, said that "with the move to 2-Gbit/s and the 64-port count, we've been really able to make use of [the V-port feature]." However, an HDS source says the 9900 V (the "V" stands for "virtual") still supports the same maximum number of servers it always has -- 4,096 -- because its operating system is currently unable to handle more than that.

    In any event, HDS's aggressive attack on EMC Symmetrix has paid off. Analysts expect that it will overtake EMC in market share at the high end of the enterprise storage market this quarter, with IBM Corp. (NYSE: IBM) hanging tough in the No. 3 spot (see HDS Gains on EMC).

    But while HDS, the worldwide storage sales and marketing subsidiary of Hitachi Ltd.
