Storage utilization is a part of every storage manager's life, with users complaining about having too little space and management demanding users make do with what they have. Even with growing disks and rapidly shrinking per-GB prices, there's always too much storage installed and yet too little available for use.

  • Storage managers grapple with Windows

    by  David Braue

    The spread of Windows into ever-more serious applications and the growth of data on Windows servers means that more storage managers are attaching Windows hosts to their SANs. Along with that comes the need to decide whether Windows-based storage management software is the way to go.
