Deal with HyperFlex: Sizing A New Cluster Utilizing the Sizer and Profiler Instruments


On this ‘Deal with HyperFlex’ weblog, we’ll zero-in on totally different elements of the Cisco HyperFlex (‘HX’) hyperconverged system and methods to make HX work greatest for you and your group. This version will illustrate on dimension a cluster once you may not have all the small print of the workload labored out. On this state of affairs, HyperFlex Profiler is the appropriate method to study extra in regards to the workloads.   

Throughout my time in gross sales, groups typically requested me to dimension a HyperFlex cluster and supply a buyer quote. It was customary to have many extra questions than the workforce or buyer might reply in regards to the software. Usually, they would supply me with an Excel sheet with some CPU and reminiscence values. That may be a nice begin, and it gave me deep perception into the client’s software. Nonetheless, an software profile is just not solely about averages of CPU and reminiscence.  There are a number of extra parameters wanted, together with the efficiency and latency peaks. With the client’s permission, I’d run a HyperFlex Profiler of their surroundings to achieve extra details about their software. Earlier than putting in the OVA on their vCenter, I’d clarify what HyperFlex Profiler is and the way it helps with sizing their new HyperFlex surroundings. 

HyperFlex Profiler 

If there is no such thing as a historic perception into the potential clustered software surroundings, then begin with HyperFlex Profiler. HyperFlex Profiler will collect information on the vCenter surroundings and consolidate that mass of knowledge to a single, simply digestible file. This file will shortly dimension the cluster after importing it into the HyperFlex Sizer device and paint a clearer image of the surroundings and workloads. 

Nonetheless, profiling the surroundings is just not a fast hit in a brief time frame. The most effective method is to run the HyperFlex Profiler for a minimum of seven days or, ideally, 30 days. An extended measuring interval ensures you seize information when “finish of the month experiences” are run. In fact, don’t simply measure the surroundings throughout a weekend when there’s little visitors! You should definitely seize a minimum of one logical enterprise cycle for that software. 

The HyperFlex Profiler is an OVA put in on a VMware surroundings. The one configuration is to offer (read-only) entry to the vCenter surroundings and outline which servers the HyperFlex Profiler will monitor. A number of servers and/or clusters might be chosen. For environments operating several types of workloads, it is strongly recommended to isolate them by deciding on the servers of their environments – as an example, the VDI or the SQL surroundings. In fact, deciding on all servers and workloads can also be an possibility. Remember the fact that you’ll have extra overhead this fashion. 

When it’s monitoring the surroundings, you will note the next: 

Extra particulars in regards to the surroundings might be proven in different tables and graphics, that may be exported in pdf format. 

It’s important to see the peaks of the surroundings. This fashion, you can also make positive the brand new HyperFlex designed cluster can deal with the workload, and guarantee there’s room for growth. 

There are totally different graphs within the HyperFlex Profiler. Right here you’ll be able to see the metrics of the storage reads. Right here, you’ve gotten extra perception into the steadily used block-size of the surroundings. That is considered one of them:

The subsequent step is to make use of the facility of the HyperFlex ProFiler to create a invoice of fabric out of all the knowledge from vCenter.  The info of the HyperFlex Profiler might be manually or mechanically downloaded and uploaded to the HyperFlex Sizer. 

HyperFlex Sizer 

The HyperFlex Sizer is a web-based device (https://hyperflexsizer.cloudapps.cisco.com/) accessible to each companions and prospects. With this device, you’ll be able to add your private, mostly used workloads to a HyperFlex cluster and have the sizing device determine the best choice. HyperFlex Sizer takes the HyperFlex greatest practices into consideration when calculating the optimum answer. 

Moreover, you’ll be able to customise the sizing device, utilizing solely the popular elements the client needs to see within the new HyperFlex surroundings. Completely different parts, like CPU, reminiscence, sorts and sizes of drives, and extra, might be personalized. 

Importing the info of the HX Profiler to the HX Sizer is fully easy. After claiming the HX Profile into the HX Sizer, the device will produce a sensible Invoice of Supplies that may be the baseline of a  dialogue along with your companion about the perfect answer in your purposes. 

Here’s a screenshot of the HyperFlex Sizer the place a HyperFlex cluster is calculated with the requested workload:

A variation of HyperFlex clusters could also be suggested. That is attainable once you wish to have totally different workloads, every with their traits. 

It reveals the quantity of HyperFlex or compute nodes, what kind of nodes and  contains all of the components which might be wanted to create the answer. This fashion, you don’t should configure the whole lot manually, eliminating human errors.  

Create an estimate

As soon as you realize the entire dimension of the brand new HyperFlex cluster, companions or Cisco consultants can simply add the Invoice of Materials to Cisco Commerce Workspace (CCW) and estimate the HyperFlex cluster.  

In CCW, the estimate might be transformed to an order.  

Abstract 

Every time there’s little to no details about the workloads that may run on a newly designed HyperFlex cluster, begin with the HyperFlex Profiler. Start gathering information,  together with important CPU, a storage profile and reminiscence measurements. 

After operating the HX Profiler for the advisable minimal of seven days, you’ll be able to add the report back to the net HyperFlex Sizer device and begin sizing a brand new HyperFlex cluster with that information.  Then, the HyperFlex Sizer creates a helpful bill-of-material. After mechanically importing it to CCW, the companion or Cisco groups could make an correct and environment friendly estimate of the cluster sizing wants. 

to grasp your software and dimension of the brand new

HyperFlex clusters.
