There is no official single guide for this afaik.
If you can reach bmc support for this , or seek bmc professional services help , they can provide u something.
I believe we are working on an HA guide.
do you mean 'HA' or 'DR' ? i'm not familar w/ VMware FT - what is that?
and what are you trying to accomplish here - have another site available to take over if your site fails, or have redundency w/in a single site?
HA/DR really depends on your infrastructure. BSA can be implemented to take advantage of the lower level technology available in your environment. So the questions are, what do you have for storage (SAN replication, rsync, etc.); for database (SQL replication, Oracle Dataguard, import/export); and vCenter’s Fault Tolerance via virtual lockstep should work … but the OS of your BLAppServer and how your FileServer is configured will determine which approach is best suited for your environment.
If you are on Wintel AppServers, in NT 6.x … you can’t persistent mount a share, it’s only available in the user context and not system wide … also RSCD Agent is not UNC aware, so to leverage the replication feature of DFS, then you’d have to install the agent on each of your DFS servers, then DNS alias them … and configure the AppServer to us the DNS Alias.
I am looking for both HA and DR, but the primary emphasis is on high-availability. Likewise, I am more interested in redundancy within a single site but multi-site availability and survivability is important, too.
By the way, I still have a document addressing the latter situation written by a certain BladeLogic engineer a few years ago when I was a BladeLogic 7.x customer and he was my post-sales engineer. That is still a good document.
VMware vSphere FT (Fault Tolerance) is actually kind of cool. What it does is keep a second copy of a VM running on a second Host in "lockstep" with the primary VM. That way, when anything happens to the primary VM (or even Host), the second VM takes over almost instantaneously: literally within a few milliseconds, if that. This is completely seamless and transparent to the enduser and applications. In our case, running the BSA infrastructure on VMware FT virtual machines -- although, I would still tend to use Oracle RAC and DataGuard for the database but that's probably just me -- would provide both the HA and DR required. Do you know if anyone has tried it?
By the way, I've always thought that VMware vSphere FT (Fault Tolerance) and VMware vSphere HA (High-Availability) were misnamed. To me, it makes more sense to call the "always on" version HA and the "failover/restart" version FT. But that's just me; my own personal issue and obiter dictum.
I am really looking for BSA guidelines for HA (and DR, too, to an extent). This is not for a particular customer or client -- although I do have one in particular who is beginning to ask questions along these lines -- but for general knowledge. The forthcoming documentation that Bill references should be good.
Me personally, I would tend to think using VMware vSphere FT and Oracle RAC would be ideal in a perfect world but as you mention, it really depends on the customer's infrastructure. What happens if the customer does not have and/or is unwilling to invest in VMware vSphere FT and Oracle RAC and Dataguard (all of which are substantial investments)?
And the other thing is, has it even been tried before?
As a relatively "simple" solution, I would think that using load-balancers and DFS replication should work. I know BSA has been implemented with the former before but, as you mention, the latter may be problematic. Again, my question is, has it been successfully done before?
That is why I am looking for any documentation. What has been tried before, what has been the results, what is recommended and why. Some of that information is out there but I was wondering if it has all been collected and organized (and expanded upon) in one place.
Perhaps a couple of weeks asking but I am a Solutions Partner but do not have access to the link you posted:
I put in a request but can access be expedited?
I have someone else asking about BSA high-availability.
That document has been posted to an internal-only area of Communities. I'll contact the owner to see if it can be made available outside of BMC and let you know.
I will say that you guys answer quickly!
