IBM PowerVM vs. Scale Computing Platform

IBM PowerVM only is available on IBM POWER machines. It makes live much easier, compared to bare metal machines (OPAL) or machines with KVM. Personally I would not like to manage systems that don't have IBM PowerVM. The current line-up always includes IBM PowerVM (firmware built-in).

Scale is best suited to environments that do not have excessive external or proprietary peripherals. Integrating with tape drive backups or robot tape libraries can be problematic. The most effective use of Scale systems is for companies running multiple instances of the same operating system. The hypervisor's code/file-sharing nature does an excellent job managing new instances while keeping the increase in storage to a minimum.

• IBM PowerVM is reliable and fully redundant with no single points of failure
• Once it is set up, there is not a lot of maintenance that needs to be done on it
• It gives you a lot flexibility by using features like LPM

• Simplicity - I do not have to create storage buckets or micromanage anything.
• Efficiency - Lower power use since moving to a hyperconverged environment.
• Scalability - Adding additional hardware is easy, and increasing things like the amount of RAM or number of cores is easy.

• Each LPAR comes with a profile that sets a minimum, desired and maximum capacity (like for CPU). You can freely change the allocated CPU between the minimum and maximum on-the-fly. If you want to change the resource below the set minimum or above the set maximum, you need to shutdown the partition first and change the profile. It would be nice if there was a way to do that without downtime too.
• (Setting the maximum very high is fine for CPU but not for memory as it allocates a fixed percentage of the maximum (not the current) size for internal housekeeping).
• When you manage your Power system with an HMC, a lot of firmware updates can be done concurrent (on-the-fly), not requiring a power-cycle of the machine. If you use Novalink to manage your systems, this proces becomes broken and you need downtime on your physical system. You can use Live Partition Mobility to move every partition off of this system first, but still...

• Display the IP address of the node on which the VM is running on the Devices (gear icon) tab. This would allow me to manage my Microsoft license easier.
• During the on-boarding I missed the step to install the Scale Computing Platform tools, and we didn't notice this until I had issues with backups. It would be helpful if some kind of alert notification would display on a VM card if the tools were not installed.
• Add a new health or diagnostics tab that would display alerts, diagnostic tools, performance concerns or pattern anomalies.
• Some kind of email/alert when a disk reaches near capacity

The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.

I'm on the fence about renewing the support contract. The reliability of the HC3 makes it difficult to spend the cost of the renewal which is higher than the costs prior to Scale. I'm convinced if we were a larger district that the savings would be tremendous and I wouldn't hesitate to renew. In our specific situation, it may be more feasible to pay per incident.

Since it is built into the firmware (hardware) it requires no separate installation (except for the Virtual I/O servers, if you need those). Both HMC and Novalink (with PowerVC) support IBM PowerVM well and offer a user-friendly interface to setting up LPARs and making changes, most on the fly. Modern systems also give insights into performance, power consumption etc. A lot of separate tools exist to show more details, like LPAR2RRD, IBM Instana, IBM Turbonomic etc.

Everything you need to do is point-and-click easy. If you are the kind of admin who wants to edit every config file and endlessly customize your environment, then Scale may not be for you. On the other hand, if you just want it to work really well, and do what they told you it will do, then Scale is the ideal system.

Never had an outage or an error. Once a hard drive failed, but Scale kept on working flawlessly without interruption.

Performance has been just as outstanding as reliability. I have never experienced delays in any aspect of usage.

We had one need for support post-setup, and the person who answered the phone was the support person I needed. No transfer, no level one, and our accents were similar enough that we understood each other easily. The problem was actually in my switch, not with Scale, but the support person still assisted me and got the entire cluster up and running again in under 30 minutes. They are truly a partner not just a vendor.

I did not do in-person training.

Because Scale is so simple, the training is just as quick and easy.

The implementation was very easy. We had Scale support on standby and they were ready and eager to help if needed. The process went so fast the employees in the organization did not even know it was done.

IBM PowerVM is the best and most stable product in the virtualization market. It gives the best performance with IBM Power Server, especially its best solution, where we have to run critical applications and save applications licensing costs. It provides a lot of good features like LPM, shared processor pool...etc, which makes the environment more flexible.

As mentioned previously, not having to worry about the compatibility between your hardware, hypervisor, and VM OS is a great help. On the downside, there is less ability to get deep in the weeds with your own system. Much of the Scale HyperCore OS is locked down intentionally, which prevents technical users from having much insight on broad error messages without support intervention.

HC3 is one of the best products I have purchased for our district. It is unbelievably reliable to the point that they shoot themselves in the foot on support contracts.

• It has provided the performance we need during month end and year end closing cycles.
• It has been very reliable with little to no downtime.
• We have been able to stretch our IT dollars because the refresh rate on IBM Power can run for years. Also, we have been able to add many more VMs to physical machines than other platforms can run.

• With the high cost of the leading competitor the savings starts day one and saves every year after.
• Scale can be administered by a tier one technician so cost of labor is reduced.
• If there is a problem like a cyber attack, the savings kick in with the least amount of downtime.
