Q6: Another on flash. Today's enterprises need to provide real-time data access and apps need to overcome storage bottlenecks. How is Flash helping to achieve this?

Dan C. Barber A6: IOPS

Nick Howell The race to 0us is on. It's all about that latency. Period.

Dan C. Barber A6: @datacenterdude agreed. But my question is how many people and apps really need near-zero latency?

Adam J. Bergh @dancbarber Is flash fundamentally changing how apps are designed?

Gilda Foss A6 : Flash is being leveraged for high-performance applications that speed response time. This is a great example of a practical application of flash. #boom

Mark Welke Storage bottlenecks have a high cost associated with them. Eliminating the bottle neck means more efficient servers, which equates to less of them. More importantly less software licenses, this is where the real saving take place.

Nick Howell You wouldn't be surprised. Some of the biggest names that host data for the consumer digital products you use every day run on EF550/560, and that was a core requirement of all of them.

Dan C. Barber @ajbergh Flash is showing app developers the potential they have. Case in point: what if a major retailer could get realtime info on every purchase a customer made right at the Point-of-Sale device?

Gilda Foss @DataDefiner Flash, especially the way NetApp has designed their FlashRay, uses global inline deduplication, byte-granular inline compression, variable length block layout and adaptable performance.

Nick Howell Mark nailed it. The biggest cost-savings is in less hw required, which equates to less licenses and support contracts needed. Doing more with less always saves. Been NetApp's M.O. for a long time. "Go Further, Faster"

Data Definer @GildaFoss Flash also works great with source-side dedupe, inline compression, etc. I recommend server-side flash and/or AFAs all the time!

Q8: With storage needs growing exponentially, how do enterprises who are looking at all flash solutions integrate with larger capacity needs?
2 Votes Vote
Nick Howell Anyone that thinks the whole datacenter will be all-flash all-the-time for all-the-things is silly in the head. There will always be a need for "cheap & deep" for WORM, archival, cold storage, and off-site long-term retention.
3 Votes Vote
Nick Howell (cont) and that will still constitute a MAJORITY of total data in any enterprise.
1 Votes Vote
Gilda Foss A8 : The most successful enterprise storage strategy will continue to be one that uses both flash & hard disk. Over the next 5 yrs, hard disks won't begin to approach flash perf, & flash won't begin to approach the capacity needed. #justfacts

Dan C. Barber @datacenterdude agreed. there will always bee the cheap & deep

Gilda Foss A8 : Bottom line is that the all-flash array that have no integration with existing hybrid flash/disk arrays, will be the hot rod in the garage of IT. Fun to tinker with, but not the reliable storage workhorse IT needs. #period

Rip Wilson A8: Performance disk is in trouble, but capacity disk will have a big $/GB advantage over even the cheapest for of flash for a while. Hybrid architectures (flash+disk), whether on-prem or leveraging the cloud, are the new normal.

Adam J. Bergh A8: Hybrid approaches - Flash as a tier or a cache to traditional media will be the new "normal" in the near term
2 Votes Vote
Gilda Foss A8 : Enterprise storage continues to move rapidly to a hybrid model, where models are applied both within & beyond the enterprise's traditional boundary between hardware it owns & manages.

Nick Howell @DataDefiner Good point, Brian. I still hold firm that DRaaS will become one of the first major uses of public cloud from the enterprise. From a simple capacity play. Hell, I do it at home!

Dan C. Barber @GildaFoss Everything is moving toward hybrid. There isn't a one-size-fits-all SAN, nor is there cloud, compute, network, application.

Ravi Mahendrakar All flash for storage simply doesn't scale... data has tiers and so will storage. With Software Defined Storage #SDS, customers can look creating storage management policies and automating data movement in line with "data tiers"...

Q4: What are the top three challenges you’re experiencing in optimizing your SAN environments?
2 Votes Vote
Dan C. Barber A4: Faster data access is key; #flash is certainly helping that.
6 Votes Vote
Nick Howell The top three things I hear: a) Ease of setup/maintenance b) connecting to host environments (i.e. proper zoning/config) and c) Staff doesn't scale as well.
4 Votes Vote
Dan C. Barber @datacenterdude Agree on the staff part. When personnel is one of the biggests costs, a scalable SAN is very important to business effectiveness.

Ariana Gradow .@ripw5280 I'm not SAN expert but I assume that it is important to pay attention to the fundamentals of SQL Server

Nick Howell (cont) These are not new problems. As much as we want to believe Flash will be the end-all, be-all for SAN, the reality is many of the core problems still exist. SAN is still SAN.

Dan C. Barber @arianagradow it is certainly fundamental to understand your workloads. Too many people just say "put it on flash and don't worry about it."

Dave Vellante @datacenterdude I agree. Flash deals with mechanical latency and it can help with copy creep but you still need a management stack
