Ask the Expert: Multicore Optimization (MCx) in the New VNX
|
|
Ask the Expert: Block Deduplication and FAST Suite Tiering in the New VNX |
This Ask the Expert event will address your questions about the multicore optimization (MCx) in the next-generation VNX.
MCx distributes VNX data services across all cores, ensuring that cache management and back end RAID management processes take full advantage of multicore CPUs and allowing cache and back-end processing software to scale in a linear fashion. When coupled with FLASH 1st, the VNX with MCx delivers the performance of flash with the efficiency of tiering, providing:
- Full advantage of the low latency of flash
- Progressively lower $/IOPS at scale
- The lowest $/GB for inactive data
Your hosts:
| Dan Cummins is EMC's Director of Engineering for MCx. | |
| Phil Trasatti is EMC's Director of Performance Engineering for the Unified Storage Division. He has been a senior engineering manager, consulting software engineer, and architect for products in the networking, storage and video markets, and is experienced in all aspects of product delivery, software development, product deployment and field support. | |
| Andrew Maffessanti was hired by EMC straight out of university in 2006 and has been working on the CLARiiON and now the VNX Product line, specializing in array performance. He has a BA in Information Science & Technology from Mercer University. |
This discussion will be moderated through September 16. Follow the thread in your inbox (see option on right) to receive updates.

dear experts, with so much power at your disposal now ..why dedupe was not implemented as an inline process but rather a post process job.

First of all: MCx is great. Second: MCx was inevitable. The old architecture simply was a bottleneck.
My most important question is how to size.
I.e. a VNX5600 sweet spot limits to 50x EFD when their IOPS are fully utilized. What will the limit be if 70% read and all IO's are mirrored by MV/S? And what if they are mirrored with MV/A? And What with RecoverPoint/SE with VNX-splitter?
Are there rules of thumb which indicate a % of 'IOPS-headroom' to reserve for replication? And what the impact is with different flavors of replication?
And what about the impact of RAID5/RAID6/RAID10 on SP utilization with MCx?
Also interesting is the Active-Active dual-lun ownership feature. Is there a whitepaper how this is being done and how cache coherency is maintained?

It's great that MCx now allows active-active LUN assignments. When do we expect to see Pool LUNs added to this functionality? Will it be a .X release or will this come in a later full-version upgrade?

Q1. What are the technical items, that demonstrate how the VNX with MCx delivers the performance of flash with the efficiency of tiering when coupled with FLASH ???

Is there any performance difference between using 8GB FC VS 10GB iSCSI on Block Storage

Have the best practices documents been posted already?

that's impressive, but does 5600 have more cache than 5500 (we know it has more cores) ?

When will I be able to get certified on the new VNX? I mean: has the course material already been enhanced and when will the exam be available?

So this means the VNX will start to look like a VMAX with the exception that a VNX only has 2 engines?

i am curious how big your data set was. With so much more memory in 5600 you probably never went to disk ?

At this time the Best Practices Guides are still being developed.
