Configuring Your ReadyNAS
v1.0, October 2007
SMTP
The ReadyNAS device has a built-in e-mail message transfer agent (MTA) that is set up to send 
alert e-mail messages from the device. Some corporate environments, however, might have a 
firewall that blocks untrusted MTAs from sending out messages.
If you were unable to receive the test message from the Alerts Settings tab, it might have been 
blocked by the firewall. In that case, specify an appropriate SMTP server in this tab.
Internet Service Providers (ISPs) for home might also block untrusted MTAs. Furthermore, they 
might allow you to specify their SMTP server but requires that you enter a user login and password 
to send out e-mail—this is common with most DSL services. If this is the case, simply enter the 
user name and password in the fields provided.
Performance
If you wish to tweak the system performance, select Performance from the main menu. Note that 
some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS) before 
enabling that option:
NETGEAR recommends that you select the Disable full data journaling only if the NAS has 
UPS protection. Without battery backup, there is a small chance that parity written to a disk in 
a RAID set might become out of sync with the data disks if a power failure suddenly occurs, 
possibly causing incorrect data to be recovered if one disk fails. Without full data journaling, 
disk write performance increases substantially.
