The only problem with the WORM (write once, read many) feature is it does take up more space than if you just wrote a file, because it writes stuff twice. But it works for us for chain-of-custody scenarios, and it's built into the file system itself. Also, on the PowerScale system, because of the magic that it does "under the hood," it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern. It's the secret sauce of protecting your data and that makes it a little disconcerting for someone who is used to seeing if a directory is using 5 MB of space. So if you have a directory using a terabyte of space, it might be using a little bit more because of the way that the system handles data protection. That is something you have to get used to. Also, a lot of people are not used to the tagging or the description in the InsightIQ application. We're used to using the normal nomenclature of terabyte, petabyte, etc. They utilize TB byte and PB byte. So you have to understand the difference when InsightIQ is telling you how much storage you have. It's different than what we're used to. It uses base-2 and the world is used to base-10. Discerning how much storage you actually have, from the information in InsightIQ, takes a little bit of math, but it's not very difficult. I wish they had an interface in there where you could click and it would report in the way the industry is used to, which is in terabytes and petabytes. It's nothing major, just something you have to get used to when you're looking at it.

Some improvements to the NFS support would be of interest to us. I think that will be available next year.

There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times.

Simplify where you can. If you have a need for tiering, then that can be okay, but it can behave in ways that you may not expect. If it's at all possible to simplify and stick with one node type, your consistency will definitely stand up a little better. If you do have a workload where tiering makes sense, PowerScale does do a good job of that. That's the only real, "Gotcha," that we've run into.

The replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement. There is a lack of object support, which they have only just rectified.

There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things. The refresh of the interface with version 9 did help a lot of the things. They are at least improving it.

The solution lacks a cloud version. It would be useful if the solution could direct to AWS or Google Cloud effectively or have an AWS version. With the global lockdown conditions, you can't get to the site. It would be easier if it was connected to the cloud. The solution can be a bit complex for those not well versed in the technology.

The solution isn't suitable for small environments or small customers. The price point would be too high for companies that don't need a very large amount of storage space. The redundancy is a little bit expensive.
