Published: 20 Oct 2012

WHEN IT COMES to director-class switches, Cisco's new director is a behemoth. Announced last month, the MDS 9513 packs in a maximum of 528 ports. That number comes by way of Cisco's new 48-port 1/2/4Gb/sec switch modules. Other 4Gb/sec switch modules are available in 24- and 12-port increments, are fully compatible with other Cisco director chassis (the 9505 and 9509) and will ship this month, says Paul Dul, Cisco's director of product management. With the new 48-port module, Cisco's older 9509 chassis goes to 336 ports, the next biggest director on the market.

      Storage Bin: All too often, storage vendors treat small- to medium-sized businesses as second-class citizens. SMBs have the same needs as enterprises, so rather than giving them hand-me-downs, vendors need to create products specifically for this group. Vendors just might find that those products have the features that enterprises want, too.

    • Data storage security trends by Jon Oltsik

      2005 was a big year for storage security, with major vendors doing more than just paying lip service. Vendors are beginning to integrate security into new products or add encryption capabilities. But there's a lot more to do in 2006 to build a secure storage infrastructure.
