IBM Storage FlashSystem, an all-flash storage array, delivers ~2 PB of effective capacity per single rack unit. Engineered with unique FlashCore Modules, it offloads data services including compression, encryption, deduplication, and ransomware threat detection ensuring optimum performance and resiliency.
IBM Storage FlashSystem is hands down more usable, feature heavy and reliable. Code upgrades are one of the better aspects, not risk of host timeouts due to port pauses. Response times have also been better, as well as inter-site replication.
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
Top choice for IBMi integration. In general, it's a very good solution for quite a lot of customers. If you need a 3 site replication solution (HA + DR) maybe it's not the best solution, unless you use SVC. FlashCore Modules have very powerful compression rate, while mantaining good performance: high IOPS rate and really low latency
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
Definitely we need to be able to extend a volume that is part of a mirror pair or Policy-Based Replication(PBO) on the fly.
Expansion of mirrored volumes/volume groups should resynchronise only the changed data (Almost like making use of change-volumes) and not trigger a full resync.
Please allow us to select downloading drive microcode also from Fix Central directly onto the flashsystem like with updates.
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.
The integration into our SVC and the midrange systems are very well working. We do use cross site replication and global mirror which in turn is easy setup and the consistency groups are well maintained. The storage does global mirroring but also internal cross room replication as well. The integration of cloud object storage also helps in tiering the overall system.
Yes. The last really issues I've seen in the environments of my customers were back in the "Storwize" era of systems. Issues with code updates or sometimes rarely failing critical components. BUT: since every component is at least dual redundant even back in that day real outages were very rare. And today in the "FlashSystem Era" the systems are so reliable and available even during code updates there are no complaints. I think the 5 or 6 9s are completely achieved.
Latency and throughput have been excellent. The compression is done natively on the NVME modules so we do not see an impact there. the distributed parity does not seem to impact write speeds at all. We have found database performace has increased quite a bit over our old hybrid storage solution.
Having a single tier of performance makes it easy to set up SLAs for workloads.
I would rate the overall support for IBM Storage FlashSystem with a 10. The response times have consistently been fast, and the support engineers always come prepared with relevant questions and practical solutions. They demonstrate a deep understanding of the product and our use case, which means issues are typically resolved quickly and without unnecessary back-and-forth. This level of support has been especially valuable for our SAP environment, where uptime and quick resolution are critical.
Very good traning by experienced personnel. I attend instructor led sessions on IBM TechExchange and STUs before as well as IBM workshops for FlashSystems at IBM Böblingen which I helped to prepare and improve after piloting them. Absolutely nothing to complain about FlashSystem training in Germany or USA. So: all good here!
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.
I'm using cognos - especially cognos reports - as a part of IBMs Storage Intelligence software to manage datacenters and report storage and overall resource consumption to my customers. The software is reliable and - my customers who are using cognos in their businesses - say that they are very satisfied about the scalability of cognos. I can give it only an 8 rating because of the quite heavy resource footprint...
