inquiry problems - Assignment ExampleRAID level 0 lacks pleonasm and gap tolerance and therefore a permanent data loss often occurs when one drive fails. On the other hand, a murder data loss can only occur on RAID level 5 in the event of two or more drive failures. RAID level 5 has improved fault tolerance and can only experience a permanent data loss when 3 or more drives in the array are lost. Lastly, RAID 10 provides a very high periphrasis and fault tolerance but a failure of more than one disk in severally sub array may result in a permanent data loss.I would exhort RAID level 5 for a web site that is backed up daily and changed often because it offers more fault tolerance, repositing efficiency and the high performance required by the web servers. On the other hand, I would recommend the use of RAID level 10 for an array holding traffic data for an e-commerce site that is backed up daily because RAID level 10 provides sufficient redundancy to protect the sensitive tr ansaction data (Delmar, 2003).Both the two giant computer vendors, Hewlett-Packard and Dell piddle developed a number of Storage area networking (SAN) and Network Automatic strategys (NAS) products with different performance, costs and storage capabilities. For example, hp has recently introduced SAN and NAS solutions known as Left Hand and the products are mainly built on open network architecture. On the other hand, Dell is offering Equallogic as well as EQL PS6510E and NX3000 lineage NAS solutions.In terms of configurations costs, HPs left hand products are generally more big-ticket(prenominal) and configuring a left hand device to store 2 TB of data and respond to requests from 8 other servers will require approximately $15. Dells Equallogic devices are however cheaper and a system that can store the same capacity and respond to the similar number of servers will cost nigh between $ 10 and $ 12 on average. It is however worth noting
