The Date/Time Screen

Use this screen to select a time zone and a time server from which your NSA can get the time and date. This time is then used in NSA logs and alerts.

LABEL DESCRIPTION

Server Name Enter a name to identify your NSA on the network in this field.

You can enter up to 15 alphanumeric characters with minus signs allowed but not as the last character. The name must begin with an alphabet (a-z) and is NOT case sensitive. Description Add text here to describe the NSA if the Server Name field is not enough. Use up to 61

characters. You can use all characters except the following: /\:|[]<>+;,?=*"~. Workgroup Name Type your workgroup name in this field. A workgroup is a group of computers on a

network that can share files.These user accounts are maintained on the NSA.

You can enter up to 15 alphanumeric characters with minus signs allowed but not as the last character. The name must begin with an alphabet (a-z) and is NOT case sensitive. Prevent NSA From

Table 18 System Setting > Date/Time

LABEL DESCRIPTION

Current System Date Time Setting

Current Time This field displays the time used by your NSA for its logs and alerts. Current Date This field displays the date used by your NSA for its logs and alerts. Date Time Setup

Manual Select this radio button to enter the time and date manually.

When you enter the time settings manually, the NSA uses the new setting once you click

Apply.

Note: If you enter time settings manually, they revert to their defaults when power is lost.

New Date

(yyyy-mm-dd) This field displays the last updated date from the time server or the last date configured _manually. When you set Time and Date Setup to Manual, enter the new date in this field and then click Apply.

New Time

(hh:mm:ss) This field displays the last updated time from the time server or the last time configured _manually. When you set Time and Date Setup to Manual, enter the new time in this field and then click Apply.

Get from Time

Server Select this check box to have the NSA get the time and date from the time server you select in the Time Server Address field. Time Server

Address Select a time server from the drop-down list box or select Specify my own time server _{and enter the time server you wish to use in the field below. Check with your ISP/network} administrator if you are unsure of this information.

Synchronize

Now Click this for the NSA to retrieve the correct time from the configured time server right _away. Time Zone

Time Zone Choose the time zone of your location. This will set the time difference between your time zone and Greenwich Mean Time (GMT).

Manual Daylight

Saving Daylight saving is a period from late spring to fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening. Select this option to manually enter Daylight Saving Time settings. Clear this option to have the NSA automatically retrieve Daylight Saving Time settings from the Internet. The NSA will download a new daylight saving resource file from the Internet every month. Start Date Configure the day and time when Daylight Saving Time starts if you selected Enable

Daylight Saving. The hour field uses the 24 hour format. Here are a couple of

examples:

Daylight Saving Time starts in most parts of the United States on the second Sunday of March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would use March, Second, Sunday, at 2:00. Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select March, Last, Sunday. The time you specify depends on your time zone. In Germany for instance, you would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). End Date Configure the day and time when Daylight Saving Time ends if you selected Enable

Daylight Saving. The o'clock field uses the 24 hour format. Here are a couple of

examples:

Daylight Saving Time ends in the United States on the first Sunday of November. Each time zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the United States you would select November, First, Sunday, at 2:00.

Daylight Saving Time ends in the European Union on the last Sunday of October. All of the time zones in the European Union stop using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select October, Last,

Sunday. The time you specify depends on your time zone. In Germany for instance, you

would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). Offset Specify by how many hours to change the time for Daylight Saving Time.

Apply Click this to save your changes. If you configured a new time and date, Time Zone and Daylight Saving at the same time, all of the settings take affect.

Cancel Click this to restore your previously saved settings.

Storage

8.1 Overview

Several NSA features require a valid internal volume. This chapter covers the management of volumes and disks (both internal and external).

Use the Storage screen (Section 8.2 on page 158) to display information on all volumes, create internal and external volumes, and configure the volume’s properties.

8.1.1 What You Need to Know About Storage

Disk

SATA or Serial ATA (Advanced Technology Attachment) is a computer bus technology that allows high-speed data transfer to and from hard disks.

1-bay NSA models include an eSATA port. An eSATA (external SATA) hard disk has the same specifications as a SATA hard disk but is attached to the NSA using a cable. It can be used either to expand storage or backup data. The eSATA hard disk is optional. You can attach one SATA and one eSATA to the NSA hard disk tray. Both SATA and eSATA hard disks are treated as internal disks/ volumes (refer to Section 8.3 on page 161).

USB-attached storage disks are treated as external disks/volumes.

Volume

A volume is a storage area on a disk or disks. You can create volumes on the internal disks and external disks attached to the USB port(s). You can spread a volume across internal disks but not between internal and external disks.

Storage Methods

The NSA uses the following storage methods: • RAID (Redundant Array of Independent Disks) • PC Compatible Volume (1-bay models)

• JBOD (Just a Bunch of Disks)

The storage method you use depends on how many disks you have and how many volumes you want to create. It’s important that you consider this carefully as all data is deleted when you re- create a volume. See Figure 8.6.2 on page 166 for details on choosing a storage method.

Note: 1-bay models configure the internal hard disk (SATA) as JBOD by default. You can modify it if you attach a second internal hard disk (an eSATA hard disk).
