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

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
