This is a fast way to back up data. Given the decreasing price of storage these days (in terms of $/GB), this can be an interesting approach, and we’ll see that in high-end environments, this becomes a sound data duplication strategy for backups of the replica database of Exchange 2007 CCR passive nodes. RAID5 We skip RAID 2, 3, and 4, because not only do they carry little advantage in terms of performance and availability, but they are seldom implemented in modern controllers. RAID5 is by far the most popular RAID level in a production environment, sometimes rightly and sometimes wrongly.

This is one of the reasons why a smaller capacity expressed by Windows is typical compared to the actual capacity of the disk drive. For the rest of the book, we refer to the binary form of the gigabyte, that is, 1024^3. Data rate measurement unit: Megabyte per second (MB/s) The data rate is the quantity of data that can be transmitted during a particular time lapse. The second is often used as the referent time period, but you will find in the various Exchange 2007–related literature that people refer to MB per minute or GB per hour.

The school’s staff have many other things to do after class and kids want to go home. Put this back in perspective with Exchange 2007: When the server reads a database page from disk, what is potentially behind each demand? Users are directly affected by wait times on storage, and this is why it’s so important to not only consider how many I/Os you can get out of a logical or physical volume, but also how fast you can get this I/O completed. Let’s consider a disk drive that can perform 400 I/O per second at 35 ms response time, and another disk drive that performs 150 I/O per second at 15 ms response time.
