1. 705N

The PowerVault 705N is similar to general-purpose servers, except that it is designed specifically to store and share files. Like general-purpose servers, it contains a processor, memory, network port, and hard disks; but like an appliance, it does not have any unnecessary or additional components—such as PCI slots or video controllers—that can affect reliability. The custom operating system is armed with only the required functionality: No system or peripherals installation is required. The PowerVault 750N is plugged into the network, configured, and then ready for use, much like a network printer. Users can map directly to the PowerVault 705N without “talking” to a network server.

Uses

  • General-purpose storage: Support various types of storage requirements for small businesses, remote offices, and corporate workgroups
  • First server: Implement the network’s first server for sharing files and static Web serving
  • Distributed storage server: Improve network performance by distributing storage and isolating network traffic in high-traffic departments
  • High-performance data protection and backup server: Use as a high-speed backup destination running remote mirroring software, file synchronization software, and popular backup packages
  • Software distribution server: Use to store images for software distribution using utilities such as Symantec® Ghost or PowerQuest® Drive Image® 2.0 Professional
  • Portable server: Use for temporary deployments, transferring files between locations, or for off-site archives
  • Temporary storage server: Use for high-speed, short-life backups when staging systems or downloading large files from the Internet
  • Personal storage: Use as your own personal server, store sensitive files away from the main system, or secure the whole server in a safe

For testing, Dell used a combination of Microsoft PowerPoint , Word, and Excel documents to create the test load.

PowerVault 715N test configuration
Dell tested a PowerVault 715N server with the following configuration:
  • Processor: Intel  Pentium  III processor at 1 GHz
  • Memory:  512 MB SDRAM
  • Storage:  Four internal Western Digital  7200 rpm 120 GB hard disk drives (480 GB total)
  • Network connectivity:  Two on-board Intel 82559 10/100 Mbps Ethernet network interface cards (NICs); the NICs were load balanced during testing
  • Operating system:  Microsoft Windows Powered operating system based on Windows 2000 Advanced Server
  • On-board RAID level:  RAID-5
  • PCI (Peripheral Component Interconnect) slots:  One
