Is there a way to load balance powerfuse
For Wisdom we have dispatchers.

If not, would it be wise to replication/mirror the PF database within SQL(2008R2) and use Windows NLB (2008R2) for load balancing??

I just can't find any 'best practices' or 'guidelines' for this.

Any info would be much appreciated.

Hi,

Each RES PowerFuse Agent has a cached copy of the database stored locally. It only connects to the database occasionally to check for changes and download the delta's in case there are changes. There is also an upload tsream that uploads session information from the Agent to the database. Depending on your settings (Security Management in learning mode, Usage Tracking aka PowerTrace enabled)this can generate some load in large environments. Are you experiencing database performance problems then?

Airdeca, thx for replying.

Actually, RES Powerfuse and Wisdom are still in test. Soon we'll bring this in production.
Before we do this I want to make sure the underlying architecture is right.

For now, both databases (PF & WD) are on a single 2k5 SQL without failover or redundancy.
Just as a safety major I want to use 2k8R2 SQL high availability, with NLB for loadbalancing. I don't predict database performance problems.

I do predict problems on the client-side because everything here, around 1000 fat clients, are wifi. But this isn't something RES or any product can solve.

How would the agents react/work on an non-persistent machine (VDI)?

Hi Patco,

Like Airdeca said, each RES PowerFuse Agent is communicating directly to the datastore. With RES PowerFuse 2010 and later it's possible to configure Dynamic Database Configuration. With this feature it's possible to let RES PowerFuse Agent communicate to a specific database (e.g. Branch Office) based on DHCP settings. More information can be found in the RES PowerFuse help file.

Ofcourse it's possible to apply database replication between the RES PowerFuse databases. The BIG disadvantage of database replication (e.g. SQL), it requires some administration to get and keep it up and running.

Load Balancing of a User session is something which doesn't take place in RES PowerFuse, but in the mechanism below (e.g. Citrix XenApp).

Regarding the non-persisent disks (i think you mean Citrix Provisioning Server), this KB article will give you some information: http://support.ressoftware.com/Modules/KnowledgeBase/knowledgebaseTreeView.aspx?id=1856

Important is to make sure the "Golden Image" already contains a RES PowerFuse cache (this prevents that a cache needs to be build at fresh boot of the vDisk).
Also make sure that the identification method of RES PowerFuse Agents is set to Computer Domain name & Netbios name or MAC-Address.
