Dell Compellent (discontinued) vs. IBM Storage FlashSystem

All in all this series great in addressing issues applications that need flash storage as a backend storage supply. It addresses the need for fast, responsive servers that need to boot quickly. It is easy to use and for the most part there are few issues and none that can't be addressed/fixed quickly.

IBM Storage FlashSystems are well suited as VDI storage for Citrix XenServer environments. Our Xen VDIs are much more responsive with the fast IBM storage attached. With the low latency, the users are experiencing much less lag while working in their Windows VDIs hosted on the XenServers. There's also less graphic fragmentation that occurs since moving to the IBM Storage FlashSystem.

• 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.

• Data Replication over long distances using Policy-Based Replication and maintaining the RPO.
• We use snapshot technology heavily and these snaps are easy to create/automate and instantly available.
• Upgrades/Updates are deployed to the system without loss of data or services.
• Sub-millisecond latency is maintained and spikes are handled and absorbed by the system during peaks.
• When connected to the internet via Storage Insights and Cloud Call Home it makes for proactive problem alerting, monitoring and resolution.
• The fact that Replication and snapshot stuff are hidden under the covers and we no longer have to create mirror pairs or flashcopy pairs ourselves. It does it within the cluster or partnership.

Incentivized

• 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.

Incentivized

• The flexiblity of upgrading the flash modules for a higher capcity needs to be allowed
• The user interface for the management console is sometimes a bit confusing
• the configuration of call home can only be done to a specific IP address but not a dns name

As flash technology evolves rapidly, vendors should [adapt] to the changes and onboard them in their products. IBM is a bit slow in adopting advanced technology in [its] portfolio. Even though the current product is good, my decision is purely based on how the transformation of the product [is] being produced and supplied to [the] end-user.

I have found the system to very user friendly. We are currently using it for on premises storage only and have not had the need to leverage any of the cloud extensions. Being able to directly connect up to 8 hosts with dual controller fiber channel is a very nice feature for such a low cost SAN, which saved up quite a bit of money by not having to purchase fabric switches. This also keeps maintenance and power costs down and saves room in the rack.

we usually have never had problems with the storage going down, ofcourse there have been disk failures as part of redundancy it works well and didnt have problems with unavailablity.

Under normal conditions the performance of the storages is very good, the only thing that can vary the performance is when we use pools with data reduction and the stored space of the pool exceeds 90%, in these cases the performance is very bad

This is not solely based on the support engineers themselves but more so that the logging and gotcha's that their array has. There have been multiple times where logs are pulled, but the folder is not large enough, and it crashes the array. Other times there are certain aspects that support either does not know of or isn't knowledgable about how to look at particular issues that could be causing problems.

Sometimes the knowledge of the support agent is quite limited and the support always has to route through the level 1 agent to screen all the informtion provided. Then its esclated to the next level support with the all collected data . The logs are always uploaded along wiht the case but still its reviewed at the lower level and then escalated / handed over to the next level if its complex issue to solve.

THe training is often selfpaced and easy to follow if you have worked previously with other storage products. The content is clear and contains all the information needed for an admin to learn. However the troubleshooting part is not always included and this is dependent on forums or other sources where the information is not accessible very easily.

I was amazed by the way IBM Flash storage provides a huge amount of storage within the limited footprint, it helped us to replace big fat storage arrays, which aided in the process of moving towards lower hardware, carbon, and energy consumption footprint. We can comfortably say that Flash helped us to host applications fast with a blazing speed and user transactions are quite quick.

We selected Compellent solely based on price. Honestly I would rate it only slightly better than a QNAP we used (which was even cheaper). If performance and reliability are factors in your decision (and they should be) I would recommend looking at something like a VNXe.

For the past six months, we have been utilizing this technology in our projects to manage a massive workload and produce swift business outcomes on a crucial production database. The IBM FlashSystem 7200, which offers high performance and compression, has so far been a great experience for us. The results and functionality of this product have delighted our consumers.

We have been able to scale this storage system whenever there has been requirement for additional capacity and performance. with the help of deduplication we have been able to build quite a robust environment.
