Technical Product Review

HP Conf idential

Sprawl Makes Inexpensive Servers Expensive

• Proliferation of file/print servers − They are cheap, sometimes

− They offer a lot of convenience− They’re everywhere

• Growing operational burden− Separate “pools” of storage − Multiple points to backup and maintain

− Compliance nightmare

• Expensive use of hardware assets− Wasted storage capacity

− Server utilization below 15%

• Poor file serving performance − Most servers are not fault tolerant

− Planned downtime is expensive

IT-Symposium 2007 17.04.2007

Traditional NAS File Serving Architecture

• A file system lives on one and only one filer – the file/print server owns that data

• File server is a performance bottleneck for all network traffic and I/O to that file system

• File server is a Single Point of Failure (SPoF)

• Multiple file servers can create uneven work load patterns and utilization is not even across filers

• Each file server is an operational burden− backed up separately

− updated with new patches

− protected against virus

− Separate free space pool
