IBM Storage FlashSystem vs. IBM System Storage DS8900F

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.

Well suited for mainframe CKD based applications. There is unmatched synergy with IBM zSeries when compared to the competition, for example zHPF, SUPERPAV, zHyperLink, cache management and replication technologies. For distributed, the fact that Copy Services Manager comes with the box is a great move on IBMs part to provide replication capability no matter what the applicaiton. I think the DS8k is less suited for smaller distributed environments. I think product overlap with V9000 in this case

• 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

• Remote Copy -- The DS8k has decades of excellent code built to handle the most demanding environments for mainframe or open systems and can be combined with automation solutions like GDPS or Copy Services Manager
• Reliability and Availability -- This is the platform that gets used for the most demanding environments, even when FICON attachment isn't required
• Continued enhancement -- IBM continues to put resources into the DS8k and the platform has advanced with the technology from z and power
• Mainframe synergy -- Poughkeepsie communicates and works very closely with the DS8k developers

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

Incentivized

• The DS8000 family still lacks deduplication and compression algorithms.
• For best results on replication enablement, optional Copy Services Manager is suggested.

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

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.

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.

DS8882F provides CKD storage in a manageable footprint. Its advantage over FlashSystem is its interoperability with IBM Z Systems

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.

• 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.

• I do not know the cost. If it prevents future system wide outages, it will be a great ROI for our company.
