Pros & Cons summary

Dell SC Series is highly scalable with federation and auto-tiering, ideal for companies requiring reliable replication for continuous availability. It delivers exceptional performance with low latency and high IOPS, suitable for mixed workloads, and supports both hybrid and all-flash configurations. However, compatibility issues with certain applications, lack of NVMe support, cloud integration limitations, and high pricing make it challenging for medium-sized companies, necessitating external solutions for key management and affecting throughput performance.

CONS

Snapshots are not possible, and certain applications like Veeam do not work well with tiering storage.
The lack of an integrated key manager in the controllers is inconvenient, as it currently relies on an external product.
Licensing is complex and the storage pricing is high, making it less suitable for medium-sized companies.
SC Series does not support NVMe storage and lacks NVMe over TCP protocol support.
Performance issues arise with SC Series, such as degraded throughput with mixed workloads and latency problems.

The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works.

The performance benefits weren't surprising, we expected that. What we didn't expect were the densification benefits that we got out of going all-flash. We're able to put more applications on the arrays because of how all-flash performs. The way some of the application profiles have responded to all-flash has been really pleasing.

One of the most valuable features is the capability to switch between all-flash to hybrid, which have have actually done for one of our arrays. We started with the hybrid, with the limited if I'm not mistaken, and then over a period of time, we swapped all the hybrids with the SSDs. This was one of the big features because it gave us the capability to not stick with just one kind of media. Secondly, since it has sorted clustering, we were able to bring in the newer boxes and have it all clustered together. These were the two main features that we really looked into, which benefited our use case from an expansion/growth perspective. Another valuable feature is the ease of management.

They have a feature called Live Migrate; it's been very, very useful.

A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers.

The most valuable features are the with back-end dedupe, and the thin nodes. For a 20TB or 60TB, we're using almost a one-to-two ratio.

I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures.

We replicate between SAN to SAN for a lot of features and supportability. It also helps us when we want to upgrade to a newer SC Series or move the data from one data center to another.

We can definitely see a need for it being a multi-controller system for customers who want to scale beyond the current capability. That's always a downside. A lot of the new systems are scaling vertically, they scale out, and the Compellent, of course, is controllers with shelves under it, so you don't scale out with it, unless you add another one. But if you do, they don't talk to each other, like some of the other solutions that we sell.

Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms. What I have said, constantly, to my partners at Dell EMC is that the clear articulation of the path is really important to us. In that vein, what I'd also like to see is, with the migration strategy that's built into this product, a lot more attention paid to Dell's - in particular - legacy platforms and how we get from some of our legacy EMC platforms onto this platform with a straight-through migration and scaling strategy, not host-based migrations and not piecemeal... Dell EMC would do well to focus more on my ability to skip a generation, rather than having me take individual hops because I can't greenfield my way into a software-defined data center fast enough. This journey of multiple hops is not helpful.

What I understand is that this is a 13 year old architecture, so it has lived its life and they're phasing it out. Honestly, we were initially struggling with the integration with VMware (but it was fixed with the VMware 6.5) and, then, it was around a 10GB network. At that time, it had the longevity to go to 100GB as well. It got us thinking about, when we go into the containerized architecture, what do we need to do to fix the infrastructure?

One option I would like to see is, when you're up on the view-screen, to be able to incorporate getting to what HPE call the iLO, the Integrated Lights-Out. To be able to get that instead of having to go back and trying to find IP addresses and re-institute those would be good. It would be good to be able to that put on the initial splash screen.

While there's always room for improvement in everything, I can't really think of a specific feature of the solution that requires immediate attention.

An issue we had was that the controller went down during an upgrade because of their upgrading the code. One side of the switch was down.

We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out.
