Info on Rx-2660 and BL 870c

Hi,

Can anyone explain me the use of RX-2660 and BL-870 Blades and thier role in the Workload Manager for managing the resources across Data Centers?

Thanks,
Muthu

Shalom,

rx2660 is an entry level stand alone server that can run HP-UX, Windows or Linux.

The BL-870 is a blade based server that essentially performs the same function.

If by workload manager, you are talking about the HP-UX based product you can use it on either machine to manage workload.

IF you give both systems access to the same NFS or central/shared storage you can distribute batch jobs among them and manage workload.

There are some very expensive Veritas products that can be used to manage workload between these two systems.

You will want them on the same OS and patch level of HP-UX for that.

Steven,

Thanks a lot for your response.

I understood that Workload Manager application can be hosted on any server and Rx-2660 or BL 870C is not a requisite.Is my understanding rite?

Can you also help me what actually an WorkLoad Manager Application contains(Is it some scripts that control the Datacenters)?

Thanks,

WLM Supports all the Integrity & 9000 Servers.


HP-UX Workload Manager (HP-UX WLM) is a resource management tool that provides automatic CPU resource allocation and application performance management based on your service-level objectives (SLOs) and business priorities. WLM is most effective managing applications that are CPU-bound. It automatically adapts system or partition CPU resources (cores) to the demands, SLOs, and priorities of the running applications. (A core is the actual data processing engine within a processor, where a single processor can have multiple cores, and a core can support multiple execution threads through Hyper-Threading, introduced with HP-UX 11i v3, as discussed below.) It adjusts the CPU allocation of a group of processes known as a workload, basing adjustment on the current needs and performance of the applications in that workload. A workload is based on the collection of processes in:

* nPartitions that use Instant Capacity
* HP-UX virtual partitions
* HP-UX Virtual Machines (Integrity VM) hosts
* Resource partitions, which can be:
o Whole-core: HP-UX processor sets (pSets)
o Sub-core: Fair Share Scheduler (FSS) groups (WLM creates FSS groups using HP Process Resource Manager (PRM))

Key uses of HP-UX WLM include:

* Using excess server capacity by consolidating multiple applications on fewer servers while ensuring that mission-critical applications still get the resources they need in times of peak demand
* Automatically reallocating system resources in response to changing priorities, conditions that change over time (night/day, month-end processing, and so on), package movement in a cluster, resource demand, and application performance
* Automating the deployment of reserve capacity so that customers pay only for what they need when they need it
* Enabling higher utilization in clusters by enabling you to define, monitor, and enforce SLOs on a server or partition that receives a failed over workload

You can use WLM within a whole server that can be clustered in an HP Serviceguard high availability cluster, Extended Campus Cluster, Metrocluster, or a Continentalcluster configuration. You can also use WLM on an Integrity VM host and within any individual Integrity VM (guest).

HP also provides Workload Manager Toolkits (WLMTK), which simplify the implementation of HP-UX WLM and allow WLM to easily integrate with third-party applications. You can download WLMTK for free, as well as learn more about it from its user's guide in the information library. The implementation of HP-UX WLM is application-transparent: You do not need to modify your applications to manage them with WLM.
