Qlikview high availability solution for Ent. client

Mon, 26 Jan 2026 18:19:17 GMT

We are working with one of the top 50 Enterprise clients and they are looking for Q high availability solution.Righ now we are targetting for 25 users and eventualley it will grow. I would like to know your experience and suggestions and one more thing, since Q uses Win graphics do we need external GPU for Qserver for better display and faster refresh.

The envinorment as follows for one site:

Software:

1. Qlik Server + Pubilsher 11 on Win 2008

2. Win IIS webserver

3. Oracle 11g on Solaris or Ent Linux.

Hardware:

1. HP or Oracle SUN -- for Q server + pub

2 x Intel Xeon ( 4 or more cores each CPU)

32 or 62 GB RAM

EMC storage

2. Oracle SUN -- for Oracle 11g DB

2 x Intel or Spark ( 4 or more cores each CPU)

16 or 32 GB RAM

EMC storage

Thanks.

How much data in your QV environment? I think you are going to need more memory if you are looking to have 25 users in the system at one time.

If you are building a scalable solution, my first suggestion would be to put Publisher and QV Server on seperate boxes.

If your client explicitely asks for a high availabilty solution, do you have a SLA with a defined availibilty percentage?

If you got really hard specs, you probably need to think not only about QV, but your complete system infrastructure.

Concerning the use of a GPU, I am personally not aware of QV making use of a GPU for calculation (maybe I missed something here). Your QV applications will be accessed via web browser, so I don't think that the server graphics card will do any difference here in terms of better display.

I agree with Rob as the first step in the right direction.

Besides, depending on the network infrastructure and the amount of data, you could set up a clustered environment...

We have estimated around 500MB QV size by end of first year.

Hi Rob,

I am a fan of yours, i gain so much knowledge from your posts and going forward i expect more from you....Rob i have a solution we are building a qlikview solution for 56 users where we have HA+DR scenerio with ACTIVE/ACTIVE, the hardware list are

1) 2*Sun Fire X 4170 M2 Server with Windows 2008 Server R2 with 64 GB of RAM,with Intel Xenon E5469 family

2) we do have SAN from Oracle (SAN ZFS 7320) for storage.

3) Load balancer from Big IP.

3) Qlikview Server License without publisher for Cluster environment.

4) we will be using qlikview webserver for Qlikview Deployment.

I wanted to achieve HA+DR Deployment with above configurations, do we need NAS? reason i have seen in one of the deployment archticure. i think we can achive HA+DR situation bypassing NAS?

Need Your thoughts and suggestions on the same.Eagerly waiting for your reply.

Regards

1. Client users could not share GPU in Server.

2.And depent on your 500M qvw, I think you need not worry about the performance if you have 64GB qvs server.

3. High availibility: i think you need cluster qvs, several web server with load balance hardware, and one more server for ETL. Only way is buy more machine...

Forgive my poor english.

If you have no nas, how could you distibute qvw from you publsher server? I think you can share directory in qvs server.

Hi ZZ,

Appreciated your quick responce on the same, just to clear here we dont have any publisher, we will be using folder mechanishm and section mechanish to hide the data.

Nas is just a specifc machine to provide folder sharing.

If no nas, qvs server must open file share .

Enterprise client and no Publisher, why?

Re: Qlikview high availability solution for Ent. client

Can you please elobrate here, to share the disk we can attach SAN to it....

Re: Qlikview high availability solution for Ent. client

Fri, 15 Nov 2013 08:08:59 GMT

that was given a way back ago, but we dont need publisher, reason we have multiple qvw's instead....just to save some bucks here.....

NAS is specialized equipment. If you have no NAS, you can deploy a server(QVS) attach SAN disk which can provide folder share.

But if you have 2 QVS as cluster. You can not attach one LUN (SAN disk) to both of the servers at the same time. Because QVS cluster is not OS-based cluster. I think QVS cluster members couldn't visit the same SAN-storage.

Hi ZZ,

Please correct me if i'am wrong here,

lets say i have Server A whic is primary server and Server B which is seconday server, and i hosted all the services on BOTH servers like below

Server A

QVWS (Active)

QVS (Active)

DSC (Active)

Server B

QMS (Passive)

QVS (Active)

DSC (Active)

QMS (Active)

Now I've attached SAN to Someother server assume server C (Something like File sharing).

With the above can i achieve the HA or Not reason i'am not attaching any NAS to it.

If you have aonther Server C attach SAN disk, serverC+SAN is actually a NAS.

In another word, NAS is a server with storage.

Thanks for your quickly reply, really appreciated your support on the same.

one more lets say Server A and Server B two different servers, a SAN is attached to Drive "E"
whcih is shared between Server A and Server B...but .without C....now can it work?

san disk is only attached to one Server（A）, and shared.

ServerB can visit the Shared disk.

But it can't attached to both of the 2 Servers.
