Dell Compellent (discontinued) vs. Dell Unity XT Unified Storage

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

Dell EMC Unity is an easy system and very flexible component and very easy to navigate while providing effective services and management of multiple project information management and the data pulling from the supported third-party platform is easy and quick. Excellent reporting features and easy to use and the analytics tools are amazing.

• 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.

Incentivized

• Dell EMC Unity has improved on the end user management experience over their older product suites.
• Dell EMC Unity once stood up is reliable and performs to expectations.
• Dell EMC Unity allows for small entry into the the product suite and can grow based on needs.

• 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.

• Alerting: receiving an alert when an issue occurs. That is good to know. However, if the alert is cleared, or somehow no longer in alarm, no email is received. At times I will receive the email alert on weekends, not knowing if the issue is resolved or not until Monday when I can access the unit. I have learned in most instances, the alert is a false alarm, which could be a problem.
• The alerting itself is sometimes not clear. For example, it tells me the link is down, we reset the connection, the link is still down, a tech was dispatched, he troubleshot, and finally the alarm cleared. This incident took almost a week. It went back into alarm after he left, then suddenly it cleared on its own.

Very cumbersome compared to other vendors in the same marketplace.

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.

Not only support for Unity, but for any Dell product, whether for companies or for the end consumer. Support is agile, helpful, and always focused on solving the problem. To date, there has been no problem that Dell's support has failed to resolve and help us with.

I have used Dell EMC Unity XT and I will say that the SC Series is better in the areas of the scalability is excellent. If I need more space, it's a no downtime solution. It's harder to get the funding than it is to get the solution itself. In addition, I like the way it integrates with our environment. These features help us use multiple soft applications. They give us an advantage versus traditional storage resources.

I was instructed to buy these arrays, but I was not given the opportunity to evaluate other arrays. We evaluated other products in the market that competed with Unity and found that the younger array built from scratch had far better features, software, and ease of use. The Unity system has a unique way of storing the data when compared with other systems.

• This storage array is a middle-range array that brings speed with peace of mind due to the stability.
• The uptime has helped us with making sure the hosts and servers that connect to this array have as much uptime as possible.
• The negative still has to be that these arrays can't seem to handle quick/high I/O usage.

Incentivized

• Less business downtime and reliability is a major business concern. DELL EMC UNITY addresses this concern well and provides robust storage.
• Investing in UNITY system is less expensive than all-flash storage systems.
• Managing and provisioning VMware disks became simpler from a single interface in the Vcenter
