We primarily use Dell ENC SC Series (Compellent) for our mixed media usage for virtual servers and physical servers, as well. This is being used across the organization, and it primarily addresses issues applications that need flash storage as a backend storage supply. It addresses the needs for fast, responsive servers that need to be able to boot quickly and has high I/O responsiveness.
- Dell EMC SC Series (Compellent) does work well most of the time, but when there are massive i/o issues such as snapshot consolidation, it seems to function poorly.
- Dell EMC SC Series (Compellent) is an easy to use array. Simple to configure volumes, add servers, and adjust policies.
- The updates seem to be easily resolvable, with very little to no issues coming from any problematic update paths.
- The GUI could be a little more updated with a lot more information regarding usage.
- There could be some assistance with high I/O times where snapshots go to consolidate. There seems to be issues when that attempts to occur, and there will times where the virtual machine stuns due to the I/O intensity.
- Modification of multiple volumes or the creation of multiple volumes is a pain in the DSM management console.

This type of array works excellent in small environments that don't have high I/O usage servers. Once the servers start to become more and more high intensity I/O, you can begin to tell that this array cannot handle the spikes. This mainly can cause issues when doing snapshot-based backups, and the I/O is high when the consolidation occurs. We have seen this happen a good amount with the SC9000 but not the Vmax array.

We use our flash based SC9000 in our main datacenter to serve all of the museum's data storage needs.
- The speed of the all flash based SC9000 allows us to host all of our servers on one central storage array.
- Reliability of the SC9000 has been key with 100% uptime over the 2 years we have been using it.
- The SC9000 has been very easy to maintain and support.
- Expensive to support after the initial warranty expires.

The SC9000 is able to store off the mMuseum's server data while being fully redundant and supported 24x7 by Dell.

We used Compellent for vmware storage for clusters used by our development group. It was used by 100+ developers.
- Very competitively priced
- No need to manage individual RAID groups
- Honestly I can only come up with 2 good things.
- Reliability. We had several times where VMFS luns would become corrupted and we'd have to move all VM's off to other storage
- Performance. 1g iSCSI performance was abysmal (although the unit we used was an older device)
- Management and Monitoring. Both management and monitoring are pretty primitive. We were never able to integrate monitoring into Nagios.

Most appropriate where cost is primary driver. Least appropriate when performance and reliability are critical.

We use Compellent as our tier one storage for all of our systems. What really sold us on Compellent vs. the other vendors was their approach to block level storage that at the time was unique. Their ability to set RAID levels based on how often that particular block of data is accessed tremendously increases IOPS for data that is most in need. We store all of our SQL databases on our main array, as well as any other business systems that require the fastest storage. I would highly recommend anyone looking for an enterprise class SAN to consider Compellent. Their feature set, support, and pricing model is top notch in my book.
- Block level RAID with data tiered based on how often those blocks are read or written.
- You can mix and match different ways of accessing the SAN, FC or ISCSI.
- They offer the ability to mix and match drive speeds and sizes within racks. This provides for larger, slower drives to store old data, while providing fast SSD storage for data that is constantly in use.
- I would like to see better options for data replication between sites.

Compellent fits very well in the mid-sized business market. I wouldn't call it a system that would do well with a company the size of Google or Apple. The cost, features, and speed is what makes Compellent a perfect fit for any business that needs a quality SAN that can scale as needed.
Our organization was merging technical teams and assets and we faced a need to consolidate our data storage solution onto a single platform for ease of management. We had storage arrays from EMC and Hitachi presently but both were aging and we needed a cost-effective solution that would provide ROI in terms of letting us get the most usefulness out of our purchased storage.
- Dell Compellent support (Co-Pilot) and the add-on service (Optimize) are critical services that Dell Compellent does very well. Alerts from the array are sent to Co-Pilot where tickets are automatically generated and customers are notified of events. Of greater importance at times is the proactive support Co-Pilot and Optimize provide by contacting us of inefficiencies in the array and consulting on resolutions.
- Enterprise Manager (Dell's "single pane of glass" management framework) is a useful tool for configuration/evaluation of the array and other Compellent products.
- Ease of management. From firmware upgrades to managing server volumes the process is much simpler than with other arrays.
- The Dell Compellent model is migrating away from the WebGUI in future controller firmware versions and is focusing solely on their Enterprise Manger product (soon to be Dell Storage Manager) for managing all of their products (arrays and NAS devices). I personally like to have multiple vectors of access, or have the option to enable these if needed. Since the Enterprise Manager product relies on a separate in-house server, this presents a unique single point of failure in the event of an outage unless other highly available precautions are taken.
- Since this review concerns Compellent as a whole, I would like to mention the Compellent NAS solution: FS8600. This is a product that I believe was acquired and customized into the FluidFS architecture as an after-thought. We have a 4-node FS cluster and have not been satisfied with the product's ability to handle SMB connections (very low for an "enterprise" product like this). We feel as if we are in a constant state of debugging the software for whatever current release we find ourselves in. Firmware upgrades have not been an issue, however Compellent support is not equipped to handle calls from FS8600 users as there is generally much shuffling and transferring of the call (it seems as if there are a limited number of qualified technicians to service this product).
- The add-on service "Optimize" is a great resource for Compellent knowledge and proactive notifications and Co-Pilot support is great for any issues that arise. The only issue with these services is that, with the way the system is engineered, the services are almost mandatory as without them you would have no way of knowing how inefficient your RAID stripping was at any given time and even if you did there would be no way for you to fix it. As a customer you have the Enterprise Manager product and a set of Powershell cmdlets at your disposal, but the complete suite of support tools only resides with support, therefore you are required to not only purchase support (which should be done regardless), but if you have a large array and a very busy environment it is a good idea to purchase the Optimize service as well. They are a benefit to the customer, but they are because they have been designed that way as quid pro quo back to Dell.

Dell Compellent has a decent portfolio of products for varying sizes of business. Their licensing model is suited for those not wanting total a la carte fare, and administration is intuitive as compared to other storage arrays. This combined with Co-Pilot support gives Dell a good presence in a vast number of scenarios where networked storage is required over a DAS solution. It's only fallback is its own NAS solution, which itself may be better suited to smaller environments.

About Dell EMC SC Series
Since it's acquisition in 2011 Compellent became a Dell product line of storage solutions (e.g. Dell Compellent Storage Center). Compellent products have been folded into the Dell EMC SC Series of enterprise flash and SAN storage devices.
