When to use Global Mode

Configuration Checklist for

PFS

Deploying the HP EFS WAN Accelerator without PFS is considered global mode. In global mode, the HP EFS WAN Accelerator performs its standard optimization of accessing data over the WAN.

Evaluate whether PFS is suitable for your network needs:

‹Pre-Identification of PFS files. PFS requires that files accessed over the WAN must be identified in advance. If the data set accessed by the remote users is larger than the specified capacity of your model or if it cannot be identified in advance, then you should have end-users access the origin server directly through the HP EFS WAN Accelerator without PFS (global mode).

‹Concurrent Read-Write Data Access from Multiple Sites. In a network environment where users from multiple branch offices update a common set of centralized files and records over the WAN, the HP EFS WAN Accelerator without PFS is the most appropriate solution because file locking is directed between the client and the server. The HP EFS WAN Accelerator always consults the origin server in response to a client request, it never provides a proxy response or data from its data store without consulting the origin server.

PFS requires an HP EFS WAN Accelerator Model DL320-520,DL320-1020,DL320-2020,DL380-3010, or DL380-5010. These models have extra disk capacity that is utilized when PFS is enabled.

Before you enable PFS make sure you:

‹configure the HP EFS WAN Accelerator to use Network Time Protocol (NTP) to synchronize the time. For detailed information about setting the date and time in the HP EFS WAN Accelerator, see the HP Enterprise File Services WAN Accelerator Management Console User Guide.

‹configure the DNS server correctly. The configured DNS server must be the same DNS server to which all the Windows client machines point to.

‹have a fully qualified domain name for which PFS will be configured. This domain name must be the domain name for which all the Windows desk-top machines are configured.

‹configure the HP EFS WAN Accelerator as a member server in the Windows 2000 domain so that the HP EFS WAN Accelerator can access the domain controller to authenticate the users accessing its file shares. In order to perform this operation, a Windows domain account is required with the privileges to perform a join domain operation.

‹you must make sure that the owner of the remote path is a domain account and not a local account.

‹install and start the HP EFS Remote Copy Utility (HP EFS RCU) on the origin server. You can install the RCU on the origin server or on a separate Windows host with write access to the data utilized by PFS. The RCU is available for download from the HP support site located at

http://www.hp.com. For detailed information, see the HP Enterprise File Services Remote Copy Utility Reference Manual.
