Network Adapter Teaming

Network adapter teaming allows the system to use the combined throughput of multiple network ports in parallel to increase performance or to provide fault tolerance. Network adapter teaming on your NAS system supports the following modes:

• Adaptive Load Balancing (ALB)
  
  
• Receive Load Balance (RLB)
  
  
• Switch Fault Tolerance (SFT)
  
  
• Adapter Fault Tolerance (AFT)
  
  
• Intel Link Aggregation
  
  
• Fast EtherChannel (FEC) and Gig EtherChannel (GEC)
  
  
• IEEE 802.3ad Static
  
  
• IEEE 802.3ad Dynamic
  
  

NOTE: When creating or removing network adapter teams, the IP address of the NAS system's LAN connections changes. To prevent disconnection from the NAS system during team configuration, connect a keyboard, monitor, and mouse to the NAS system when creating or removing teams. See "Configuring Your System Using a Keyboard, Monitor, and Mouse" in "Initial Configuration" before configuring your teams.

Adaptive Load Balancing

Adaptive Load Balancing (ALB) is a simple and efficient method for increasing the NAS system's network transmission throughput. The ALB software continuously analyzes transmission loading on each adapter and balances the load across the teamed ports as needed. Adapter teams configured for ALB also provide the benefits of adapter fault tolerance. To use ALB, the Ethernet ports on the NAS system must be linked to the same Ethernet switch.

Receive Load Balancing

Receive Load Balancing (RLB) is a method for increasing the NAS system's network throughput by allowing reception from multiple addresses. RLB can only be used in conjunction with ALB, and only the Ethernet ports connected at the fastest speed will be use to load balance incoming TCP/IP traffic. Simultaneous reception only occurs from multiple clients.

Switch Fault Tolerance

Switch Fault Tolerance (SFT) uses two Ethernet ports connected to two separate switches to provide network availability of a second switch and Ethernet port if the first Ethernet port, its cabling, or the switch fails.

Adapter Fault Tolerance

Adapter Fault Tolerance (AFT) provides the safety of an additional backup link between the NAS system and the hub or switch. If a hub, switch port, cable, or Ethernet port fails, you can maintain uninterrupted network performance. AFT is implemented with a primary adapter and a backup, or secondary, adapter. If the link to the primary adapter fails, the link to the secondary adapter automatically takes over.

Intel Link Aggregation

Link aggregation is a performance technology developed by Intel® and others to increase a system's network throughput. Unlike ALB, link aggregation can be configured to increase both transmission and reception channels between your system and switch. Link aggregation works only with compatible Intel switches. To use link aggregation, the Ethernet ports of the NAS system must be linked to the same Intel Ethernet switch.

Fast EtherChannel and Gig EtherChannel

Fast EtherChannel (FEC) and Gig EtherChannel (GEC) use performance technology developed by Cisco Systems to increase a system's network throughput. Unlike ALB, FEC can be configured to increase both transmission and reception channels between your NAS system and switch. FEC and GEC work only with compatible Cisco switches. To use FEC or GEC, the Ethernet ports of the NAS system must be linked to the same Cisco compatible switch.

IEEE 802.3ad Static

IEEE 802.3ad is a performance technology standard that increases a system's network throughput. IEEE 802.3ad is similar to the FEC standard developed by Cisco. However, whereas FEC works only with FEC-compatible Cisco switches, IEEE 802.3ad works with all switches that support IEEE 802.3ad. To use IEEE 802.3ad, the Ethernet ports of the NAS system must be linked to the same IEEE 802.3ad switch.

IEEE 802.3ad Dynamic

IEEE 802.3ad Dynamic is a performance technology standard that increases a system's network throughput. IEEE 802.3ad Dynamic uses active aggregators in software to determine team membership between the switch and the server software or between switches. IEEE 802.3ad Dynamic mode requires 802.3ad Dynamic capable switches.

Telnet Server

The Telnet server works optimally for most installations. It accepts logins from a variety of clients, including the Telnet clients shipped with Windows 2000, Windows NT®, Windows 95, and Windows 98, Windows XP, and Windows Server 2003 operating systems as well as a variety of character mode terminal clients from virtually any operating system. In addition, it can be configured to meet specific site requirements such as improving security, simplifying logins, and supporting stream or console mode.

Authentication

The Telnet server supports Windows NT LAN Manager (NTLM) for authentication of client logins. NTLM allows users to be automatically authenticated to the Telnet server based on their Windows NT login. This makes using Telnet completely transparent to users, while ensuring that clear text passwords do not pass over the network. However, NTLM must be supported on the client side of the login as well.

When users are logged in to a system that is using NTLM login, they are restricted to local drives on that system. If they need to map network resources, they can do so by explicitly mapping with full credentials.

Administration

The Telnet server is administered using the NAS Manager.

Using Secure Sockets Layer

This section explains how secure sockets layer (SSL) are used in the NAS system. It also explains how to use your own certificate, if you have one, and how to regenerate your certificate.

Introduction to SSL Certificates

Certificates contain information used to establish system identities over a network. This identification process is called authentication. Although authentication is similar to conventional forms of identification, certificates enable Web servers and users to authenticate each other before establishing a connection to create more secure communications. Certificates also contain encryption values, or keys, that are used in establishing an SSL connection between the client and server. Information, such as a credit card number, sent over this connection is encrypted so that it cannot be intercepted and used by unauthorized parties.

Two types of certificates are used in SSL. Each type has its own format and purpose. Client certificates contain personal information about the clients requesting access to your site, which allows you to positively identify them before allowing them access to the site. Server certificates contain information about the server, which allows the client to positively identify the server before sharing sensitive information.

Server Certificates

To activate your Web server's SSL 3.0 security features, you must obtain and install a valid server certificate. Server certificates are digital identifications containing information about your Web server and the organization sponsoring the server's Web content. A server certificate enables users to authenticate your server, check the validity of Web content, and establish a secure connection. The server certificate also contains a public key, which is used in creating a secure connection between the client and server.

The success of a server certificate as a means of identification depends on whether the user trusts the validity of information contained in the certificate. For example, a user logging on to your company's website might be hesitant to provide credit card information, despite having viewed the contents of your company's server certificate. This might be especially true if your company is new and not well known.

For this reason, certificates are sometimes issued and endorsed by a mutually trusted, third-party organization, called a certification authority. The certification authority's primary responsibility is confirming the identity of those seeking a certificate, thus ensuring the validity of the identification information contained in the certificate.

Alternatively, depending on your organization's relationship with its website users, you can issue your own server certificates. For example, in the case of a large corporate intranet handling employee payroll and benefits information, corporate management might decide to maintain a certificate server and assume responsibility for validating identification information and issuing server certificates. For more information, see "Obtaining a Server Certificate From a Certification Authority."

PowerVault 745N Certificate

By default, your NAS system has a self-generated and self-signed certificate. The configured SSL port is 1279.

Using a Custom Certificate

If a certification authority is present in the network, the administrator can choose to change the default certificate for your NAS system. The administrator must use the wizards to first request a certificate and then apply it to the NAS system.

Obtaining a Server Certificate From a Certification Authority

NOTE: If you are replacing your current server certificate, the Internet Information Server (IIS) continues to use the old certificate until the new request has been completed.

Find a certification authority that provides services that meet your business needs, and then request a server certificate.

NOTE: For the latest list of certification authorities supporting IIS, see the Microsoft Security website. In the By Category list, select Certification Authority Services.

To obtain a server certificate, perform the following steps:

1. Log in to the NAS Manager.
   
   
2. Click Maintenance, and then click Remote Desktop.
   
   
3. Log in to the NAS system as an administrator.
   
   

NOTE: The default administrative user name is administrator and the default password is powervault.

4. Double-click the NAS Utilities icon on the NAS system's desktop.
   
   
5. In the NAS Utilities window, double-click Administrative Tools, and then double-click Internet Information Services.
   
   
6. Double-click the local system to expand it, and then double-click Web Sites.
   
   
7. Right-click the Administration icon, and then select Properties.
   
   
8. In the Administration Properties window, click Directory Security.
   
   
9. Click Server Certificate to access the Web Server Certificate Wizard.
   
   
10. Use the Web Server Certificate Wizard to create a certificate request.
    
    
11. Send the certificate request to the certification authority.
    
    

The certification authority processes the request and sends you the certificate.

NOTE: Some certification authorities require you to prove your identity before processing your request or issuing you a certificate.

12. Use the Web Server Certificate Wizard to install your certificate.
    
    

For more information about SSL, see the Internet Information Server online help.

Using DFS

DFS creates a logical, hierarchical view of file shares that exist on servers distributed in one or more Windows 2000/Windows Server 2003 domains. DFS can help you manage file resources on distributed enterprise networks, and it enables users to locate files across the network without needing to know the physical server on which the data is stored.

Two methods are available to deploy DFS—stand-alone or integrated—into the domain.

Stand-alone DFS does not require Active Directory (AD), and does not have the full functionality of DFS. It is mostly intended for backwards compatibility and support for networks without AD. Domain-integrated DFS takes full advantage of all the intended functionality by utilizing AD. Some of the functionality domain-integrated DFS offers is load-balancing, fault-tolerance, and Kerberos-based security.

NOTE: Only one DFS root is allowed on the Standard Edition of the Microsoft Windows Storage Server 2003 operating systems.

Creating a Standalone DFS Root

1. Use the Windows operating system to create a directory on the NAS system.
   
   

This directory will become the DFS root
