Why Spamming is a Profitable Enterprise
Did you ever wonder how spammers can stay in business? Although the cost of sending email is cheap, does anybody, in this day and age, ever click through on spam? Scientists at the University of California successfully infiltrated the Storm Virus, and were able to provide some unique insights into the conversion rate of spam. It turns out that almost nobody clicks on spam, as you’d suspect. And it turns out that “almost nobody,” which translates to 1 in 12 million, is more than enough for spammers to turn a tidy profit. If only legitimate email marketers could bank on the same ratio!
MS Exchange 2007 Mailbox Server Storage Cost Calculator
MSExchangeTeam.com has posted a very useful article about the Microsoft Exchange 2007 Mailbox Server Storage Cost Calculator.
In order to move forward with various designs like large mailboxes, IT departments need to understand one of the chief costs associated with Exchange mailbox servers, namely storage. To that end, the Exchange 2007 Mailbox Storage Cost Calculator is designed to help you determine a portion of the mailbox server cost, namely the disk cost (purchase price and lifecycle power and cooling costs). The calculator helps in two ways:
1. The calculator compares a series of storage design configurations and determines their respective costs. The underlying goal here is two-fold:
a. To show that you can achieve the same capacity and I/O requirements utilizing Small Form Factor SAS disks for relatively the same cost as Large Form Factor FC disks.
b. To show that there are other disk solutions (e.g., SATA) that can be viable and reduce the disk footprint cost.
2. In the situation where you are unsure whether you want to deploy Single Copy Clusters (SCC) or Cluster Continuous Replication (CCR), the calculator can compare SCC+SAN disk configurations against CCR+DAS disk configurations from a cost perspective.
