Multiple Dell PowerStore appliances can be clustered, with the capability to connect four nodes to a single cluster. Dell PowerStore solution is used on Linux, and a customer connecting storage space from Dell PowerStore to their server can use Linux as well. We are mostly using Red Hat Linux, Oracle Linux, and SUSE.
I have implemented many boxes recently and have been working for Dell as an IMAC deploying and implementing Dell PowerStore products in Pakistan. The solution is very easy to use. Moving and optimizing workloads within the cluster is straightforward on Dell PowerStore. The workload performance delivered by Dell PowerStore is very good.
The compression and deduplication technologies of Dell PowerStore are satisfactory, with a 2.1 ratio being sufficient and meeting customer requirements. Expanding and scaling Dell PowerStore is simple. When scaling up, you add the DAEs, and when scaling out, you add the next node on the right side. After initializing the next node and connecting it to the TOR switch, you can add it to your cluster, and the new node will join the cluster automatically.
For connectivity, we can use 10G primarily because it uses IP for cluster connections. Dell PowerStore has different ports used for the cluster, management, and other activities for interconnectivity. Lifecycle control for Dell PowerStore is also better, though we normally use the baseline to upgrade by manually uploading files through IDRAC rather than through the Lifecycle feature.
Some features are not easy on Dell PowerStore. For example, changing the IP is not straightforward like on Unity or other storage solutions. You must run a command in the CLI to replace the IPs, remove the existing IP, and add the new IP. A user cannot change the IP easily and will require technical support and expertise from a partner or from Dell.
There should be an easy way to change the IP from the GUI in Dell PowerStore. In the manageable settings, anything can be changed from the GUI after installation and initialization. The other features are satisfactory and very advanced but easy to manage, with nothing difficult about them.
The IP change issue is important in Dell PowerStore as there are four IPs to consider: a cluster IP, a management IP, and two nodes' IPs. These cannot be changed easily, and the subnet mask is also involved. You need to write everything in a two or three-line command, starting from the IP, removing the existing IP, and adding new IPs one through three, all in sequence separated by a comma. There is a very small tab in the management IP modify section. When clicking on modify, it shows delete, but the delete function is not working as it is not highlighted because it can only be done with the service password.
The service password is not able to log in with the GUI and is only used to log in with the CLI. In the previous Unity, you could log in with both the service account and the GUI, where you could use either the admin or service user. In Dell PowerStore, the service user is only used with the CLI and cannot log into the GUI, which is not a good feature because you cannot perform any maintenance from the GUI.
I have not used Dell PowerStore's built-in integrations for VMware, Kubernetes, containers, or other ecosystems. However, if you are using a different model, not the T model of Dell PowerStore but the S model, which has all VMware products built-in, it would be suitable.
There should be direct connectivity between the nodes in Dell PowerStore. An additional add-on card in Dell PowerStore would allow you to add four nodes in a cluster that can connect directly to each other without utilizing switching in between. We are using two switches as VLT with RedStack, using a direct cable between the switches to become a VLT, making it a single logical switch, though the management is separate. If the nodes in Dell PowerStore could communicate directly with each other through a direct, dedicated media, like a stack cable to form a cluster, that would be a better feature.
For the last three years, I have been working on Dell PowerStore and have implemented several boxes.
I do not have a good experience with the technical support for Dell PowerStore. The technical support by Dell for Dell PowerStore is a seven or an eight, which is better. The engineers and their team were very good.

These cannot be changed easily, and the subnet mask is also involved.

We are not using CloudIQ in Dell PowerStore and have not utilized it at any time in Unity either. We call and open a case on support@dell.com instead of using CloudIQ. Most customers do not connect their systems to the internet or allow such connectivity. Therefore, CloudIQ is not beneficial for them.
Regarding the ability to add capacity in single drive increments, a single drive can be larger, but it depends on the rebuilding rate. When rebuilding capacity in case of a disk failure, a larger drive will take a longer time. There should be concern if these are slow NL-SAS drives with 4-8TB capacity, as you cannot configure them to RAID 5 and must configure them to RAID 6 instead. The rebuild will take a longer time, and in case of a disk failure in RAID 5, you will lose data. Where the pool is involved, it is easy to use the entire disk. Dell PowerStore mostly uses NVMe disk, ACM disk, and SAS disk, SSD disk, and does not use NL-SAS in the base chassis. My overall review rating for Dell PowerStore is eight out of ten.
