PowerVC 1.4 Software Defined Infrastructure and IBM Spectrum Scale 5.0.0Youtube description:
A demo for creating a Software Defined Infrastructure (SDI) using Software Defined Networking (SDN) and Software Defined Storage (SDS) with IBM Spectrum Scale 5.0.0 (formerly called GPFS). Video Transcript:
Hello, today we’re going to look at Software Defined Infrastructure, or SDI, functions available in PowerVC 1.4.0. SDI was first introduced in PowerVC during the 1.3.3 release in June of 2017 as a “tech preview”. Starting with PowerVC 1.4.0, the SDI function has been fully incorporated into the product.
Let’s start by defining what we me mean when we say SDI.
The PowerVC Software Defined Infrastructure is a combination of Software Defined Networking and Software Defined Storage. Note that it is possible to use PowerVC’s Software Defined Networking solution alone, but when using PowerVC’s Software Defined Storage solution we must also use Software Defined Networking.
Let’s look at a few typologies for PowerVC’s Software Defined Infrastructure solution.
Let’s say that you have a few servers laying around and you want to build a cloud quickly. You do not have a SAN, just Ethernet connections and servers. However the servers have local disks. Here we can take 6 POWER servers and link them together with 10gig, or faster, Ethernet and PowerVC will create a virtual SAN using Spectrum Scale on top of the Ethernet connection. Spectrum Scale provides the redundancy against failure of any server or disk.
Now for a more complex topology where the storage and data network are on separate physical networks. Here we have the storage and management network shared, and the data network separated. The storage network must be a minimum of 10gig, and 25gig is recommended.
The benefit for this type of topology is that your storage traffic is not in contention with your data network traffic. This is the preferred topology and still maintains an Ethernet only solution.
This type of solution can dramatically simplify your infrastructure. The SDI features within PowerVC enable you to build SAN-less clouds either using the local disks within the servers or backed by iSCSI disks from external storage devices.
The SDI capabilities also support both PowerVM with Novalink and KVM on Power. On top of that, a single PowerVC server can support a mix of all of these topologies – traditional PowerVM clouds, SDI PowerVM and SDI KVM on Power. This provides a single point of management across different, fit for purpose infrastructures.
Let’s look at how we would create and use this topology using PowerVC.
