How does HPE 3PAR Flash Storage differ from INFINIDAT InfiniBox? Which do you recommend?

Does anyone have experience with both NetApp AFF and Pure Storage? A number of users recently inquired about how they stack up, what are the reasons you might choose one or the other or the differentiating aspects of each product.  How do NetApp and Pure compare?

Jean Carlos Bitencourt Da SilvaHello, In the design of choice of our AllFlash storage we tested several equipments, among them NETAPP and PURE. The finalists were: PURE / NETAPP / EMC. All delivered the performance and features that we had as success requirements. But ... our choice was PURE for simplicity of implementation and management, in addition to its innovative licensing model where you have the right to use everything that is implemented and what will be implemented yet you will also have right of use. We have been with PURE for 12 months and very satisfied with the results.

Bunyamin TasdemirHello, We don't use AFF but we used 8020 SAS and 8020 SSD and we replaced them to PURE. IO problems minimized, volume limitations resolved I degraded servers ram and cpu which were working on Netapp but when i moved systems to PURE, they started working as never degraded

reviewer503028I don’t have a NetApp AFF array. Our NetApp is actually quite old so I’m sure that taints my experience but from that experience, I will say it’s night and day difference between Pure and NetApp in ease of use, support, and customer service. Pure is set it and forget. It’s been mostly hands-off since we purchased it which for our team was a big selling point. I believe the NetApp AFF we were looking at still had some quirks with how patching was done even down to updating firmware on the individual drives. The NetApp allowed for more tuning of the pools whereas the Pure managed it all behind the scenes. In a larger environment, those may be selling features for the NetApp but those things were detractors for us as we don’t have a dedicated storage admin. Hope that helps.

Hello Everybody, Can someone help me understand the differences between oracle ZFS5-2 and Oracle FS1-2? Thank you,

If have an RFP/RFI template or evaluation matrix for choosing an all-flash array, please share it with the community in order to help others out. If you email it to me ( we will have it cleansed and remove all company and private information before posting.

Which do you recommend? Dell EMC XtremIO Flash Storage or Hitachi Virtual Storage F Series?

Jeff DrennanI would personally take a look at Nimble Storage. It is all processor and memory based. You can get the same performance out of a Hybrid array from Nimble. They offer all flash as well, but performance is not based on disk I/O. Very cool technology.

The IBM FlashSystem V9000 compression is a lot higher than EMC XtremIO and Hitachi.  IBM claims to be around 4.5:1, whilst EMC and Hitachi guarantee around 2:1 for Oracle workloads on AIX.  The IBM guarantee is for 90 days from implementation whilst the EMC guarantee is there for the duration of the maintenance. How true is this IBM compression figure for general Oracle on AIX?

reviewer127386To IT Central Station and prospective all-flash (AFA) buyers: Thank you for reaching out on this topic, these vendor’s claims are confusing to many non-initiated buyers. On face value, it appears that some technologies could perform much better based on their messaging. I posted a blog on this topic here: Note that the basis for vendor’s data reduction claim do vary greatly as some vendors choose to include benefits from thin provisioning and snapshots in their factoids (aka: alternative facts). Keep in mind that any “up to” reduction value message is just that; a value achieved in lab or unique workload and not representative of average. In this case, both EMC and Hitachi choose to represent average compression results from prior deployment; no deduplication value is included. IBM provided best case as this V9000 model does not support deduplication; consequently, it creates the impression that this V9000 system delivers superior result with deduplication supported! The variation in data reduction (compression and/or deduplication) result is mainly a function of the data set, not the vendor’s technology as engineers are limited to similar latency overhead. Here is a sample of typical Hitachi Storage Virtualization Operating System (SVOS) compression and deduplication results by workload that Gartner validated: [cid:image002.png@01D27726.4E691DA0] Hitachi benchmarked internally both IBM and EMC AFAs on eight different workloads and data reduction results came in within 5% of each other’s. Data reduction services performance will also be a function of the data chunk size; as an example, a 4KB chunk size engine can achieve about 5-10% better results versus an 8KB engine. Note that this extra savings will come at the performance and memory cost. So how do you proceed as a prospective buyer to assess the value of each technology? I recommend using vendor’s data reduction estimator tool on your own data set and make your own conclusion. Hitachi estimator tool can be downloaded here: ; data reduction estimators are built-in with the similar algorithm as their AFA counterpart. As for performance impact, I would recommend reading this blog: . In the real world, you can’t have your cake and eat too… Full disclosure, I do work for Hitachi Data systems and support Hitachi enterprise flash business. I hope this information helps.
