We want to add more storage and data retention time to Foglight Experience Viewer (FxV) by using external Storage Area Network (SAN).
We found the section Connecting the SAN to the Server/Storage (or Storage) in the Installation and Administration Guide. And this section below in Features and Capabilities:
Practically unlimited storage capacity (by adding appliances or SAN):
...Beyond just aggregating appliances, a Foglight Experience Viewer can be connected to a local SAN for storage of up to 30 TB per appliance host, which is much more cost effective for customers needing more than 10 TB of history. More than one Foglight Experience Viewer can be configured with a SAN connection, allowing the total capture database size to exceed 100 TB.
We found this too:
Configuring a Storage Appliance:
Foglight Experience Viewer (running version 5.0.2b or later) can use an external SAN, connected to the appliance via a certified QLogic HBA card. A Storage appliance can also be configured without a SAN, for use with the Analysis Repository. To configure a Storage appliance used in an end user configuration, you need the latest storage hotfix file. This file was not available at the time of releasing this document. For obtaining the storage hotfix file and installation instructions, contact Quest Support
Any more details onusing anexternal SAN than is available in the documentation?
We will continue to support customers who already have SAN installed, but there will be no new installations of SAN as of Sep.2011. If you need to extend the storage capacity on FxV, you should talk to your sales rep about migrating to the R710 appliance hardware. The R710 will be a capture appliance but with much greater storage capacity, multiple TB's of local storage.
The Archiver captures data and stores data on its local drives.The Storage interfaces to a customer supplied SAN.The Archiver and the Storage cannot be run on the same appliance.
The capture box always writes the data to its local disks. Data is retained as long as it can be but the oldest data rolls off as new data is captured. Capture appliances work this way whether or not Storage is installed. When Storage gets installed, the capture appliance transfers data (in completed database segments) to the storage appliance so that it can be stored on the SAN. Once a database segment is transferred, the Storage appliance takes ownership of that data for purposes of responding to searches.
The local storage on the Storage appliance is not used for capture data. (However, if you were to enable the Analysis Repository instead of using SAN, then the Storage appliance would actually be used for data storage of the Analysis Repository). Also, the local storage on the capture appliance(s) is only used to hold the newly captured data until it can get uploaded to the Storage.
FxV does not support multipaths to the SAN (via a dual port HBA, for example). Also, FxV does not support adding additional disk space once its set up. There is an open enhancement request for each of these.
You can only select one LUN/volume. When looking at overall storage capacity the local drives on the capture boxes should not be included.
FxV will attempt to transfer to Storage up to the last 22 hours of current data and all new data. Data older than 22 hours will remain on the capture appliance (and is available for searching) until it rolls off.
