Dell Unity XT Unified Storage vs. IBM Storage FlashSystem

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.

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.

• Enables you to create multiple copies of any database.
• Data savings feature with compression.
• Integrity with VMWare, RHEL, Oracle.
• The best option is a midrange unified storage array in a customer environment.
• Some models support NMMe.
• Copy Data Management (iCDM), Data-At-Rest-Encryption (D@RE).

• 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.

• 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.

• 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.

IBM Flashsystems is always available for me, it is fiberchannel storage without the fuzz of what iscsi brings. It is a very reliable storage system, I have almost never issues with this system. The only things which go wrong are the updates because the old updates which have been staged on the disks are not properly cleaned in my opinion.

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

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.

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.

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.

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.

• 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

• Easy of use is a key aspect, as we do not have dedicated storage staff.
• Our RPO has lowered near to Zero, using PBR as replication and this is key for us.
• DR plan testing has become easier and less time-consuming, allowing us to conduct tests more frequently.
