An IP address is an integral part of the server architecture and is required by all servers, LB VIPs, NATs etc. Many customers still make use of spreadsheets, which is very difficult to automate when you have to manually enter data, and this eventually leads to inconsistencies due to the file not getting updated when a IP address is assigned, changed or deleted.

What you need is a robust high performance, highly available IP solution that you can manage from a single interface and provides  features like:

• Manage a large pool of IP addresses
• Improve availability, and simplified administration.
• User based roles and permissions.
• Provide vital operational and troubleshooting data:
  • IP address history, MAC address, Owner, Location, OS, etc.
• Reports summarizing IP address resources and utilization.

There are many IPAM solutions out there with SovLabs support for the following:

• Infoblox
• Solarwinds
• Bluecat
• BT Diamond IP
• Microsoft

I will be using the SovLabs Infoblox module in my example but if you have read this far you probably asked yourself “Infoblox has native integration with vRealize Automation, why use the SovLabs Infoblox module?”  I did some research and hopefully this information is useful in your decision making:

Differentiators between SovLabs Infoblox IPAM and Infoblox native integration vRA:

• SovLabs do not require the Infoblox cloud adapter
• SovLabs has different modules, which seamlessly integrates with each other and enhances the IPAM functionality:
  • Separate DNS and IPAM modules to allow each to be driven independently even between different providers.
  • Ability to create multiple independent DNS profiles that can drive DNS for multiple different providers independent of IPAM.  DNS is able to register against multiple domains out of the box and drive host records, CNAMEs, PTR and A records independently.
• SovLabs has pre-validation logic for IP and DNS forward/reverse duplication detection.
• SovLabs Template engine can be used for custom comments, fields in Infoblox based on vRA metadata.
• SovLabs is design for ease of use.  No Infoblox schema changes or lengthy install and upgrade process.
• SovLabs is completely policy driven, no need for custom workflow development.

The SovLabs module also has many other features which can viewed on the website here, but some of the highlights are:

• Obtain and reserve unique IP address(es) and release automatically during appropriate machine lifecycle
• Reserves unique IP address(es) and assigns to the VM NIC(s) based on IPAM profile(s)
• IPAM profiles can span multiple networks, each consisting of a network name, subnet CIDR block and gateway address
• IPAM configurations are interchangeable between endpoint providers; avoid lock-in by easily adding additional IPAM providers with other IPAM modules from SovLabs
• No custom workflows required, completely policy driven
• SovLabs IPAM configurations may also be used with SovLabs network load balancer modules

1. Infoblox user on (all) Infoblox appliance(s) with the following permissions:

12. Click on properties tab
13. In the properties group section click +Add
14. Check the box for:
    • SovLabs-EnableLifecycleStubs

    • Do not attach more than 1 IPAM profile property group to a blueprint VM object
15. Click OK
16. Repeat these steps for all blueprints that should get an IP address through IPAM.

Now deploy a VM and verify in Infoblox that the IP address is assigned to the network in the default view.

If you are a VMware administrator you know what a pain it is to manage snapshots.  Virtualization makes it easy to snapshot a VM before a patch or an upgrade is applied to an application or OS and gives you that peace of mind that you can revert back if it fails.   The reality is that users never clean up there snapshots and it starts getting used as a backup method in environments which places the burden on VMware admins to manage the clean up efforts.  VMware recommends not using snapshots for more than 3 days since it can cause serious performance, storage and corruption problems in your environment.

So how you do you handle snapshots?  A lot of customers just give up and take the chance of nothing going wrong, or they end up disabling this very valuable feature so users cannot use it all.  None of these methods are good.

SovLabs modules provides policies that control the expiration and deletion of VM snapshots as well as the ability to provide notifications to the VM owner. The VM owner is not given the option to extend the time of how long the snapshot lives and it will be automatically removed based on the lifespan in days set by the vRA administrator.

   12. 
   13. Click Next
   14. Set the snapshot scheduler.  So the scheduler you set here goes out and checks each VM if they have a snapshot that might be expiring or is expired and needs to be deleted.  Once create, a vRO schedule task is created which runs every 15min to make sure that the snapshot scheduler sends out the notification at the specified time.
   15. 
   16. Leave schedule as active
   17. Set schedule type = daily
       • most customers would pick daily
   18. Set the time to run in military format
   19. Can leave schedule end date blank to run forever.
   20. Click Submit

Enable the module:

1. Based on the set scheduler, an inventory update will automatically run and send notifications.
   • If a snapshot’s age has met the expiration day, it will automatically get deleted.
2. The last SovLabs Snapshot Configuration deleted, deletes the vRealize Orchestrator scheduled task for Snapshot Management.  It automatically creates it again if a snapshot configuration is created and scheduled task is not found.

Disable the module:

1. Login to the vRA tenant
2. Select Catalog -> SovLabs vRA Extensibility
3. Click Request on “Manage Snapshot Scheduler”
   1. Select Suspend from the Action dropdown list.
   2. Click Submit
   3. (if you want to resume this module again you can perform the same actions as above but select Action “resume” from dropdown list.
