Performance Materials Access Program Q4 Partner Update EMC Confidential - Not for Redistribution
Non-Disclosure and Disclaimer • This information is EMC Confidential and must not be shared with unauthorized parties without prior written consent of EMC Corporation • EMC makes no representation and undertakes no obligations with regard to product planning information, anticipated product characteristics, performance specifications • Performance Data is provided by EMC as an accommodation to the recipient solely for purposes of discussion and without intending to be bound thereby
Agenda • PMAP Review • VNX Training Material • VNX Performance Data • VNX Tools • Summary
Performance Materials Access Program • Benefits of SPEED (Symm)or USPEED (VNX) performance group membership • SPEED/USPEED names for EMC internal use • Develop performance skills and knowledge in the Partner community. • Engineering sponsored program to empower technical resources to answer performance questions and to solve performance problems more effectively • Performance calls and updates as needed • Guidelines and Detailed performance data • Access to Performance Tools • Nomination form and Open book test to access program
Requirements Velocity Consolidate Specialty Partner • EMC Proven Professional Implementation Engineer or Technical Architect • Either block or file specialties are initially acceptable • Completed the Unified Performance Workshop • Waved until new VNX Performance Workshop becomes available • Unified Performance Workshop • 4 days Instructor Lead Training • The Performance Workshop is an advanced level course designed to provide partners with the ability to design and implement Unified solutions with performance in mind. • Your Partner manager must be aware of your involvement and nominate you • Application process documents on Champions Portal
Responsibilities • EMC, the members of the SPEED community must sign an NDA and covenant in which they pledge to safeguard the tools and information that Engineering provides to them. They are called to act as a resource within the organization to support co-workers and customers, and to cooperate with Performance Engineering on special initiatives. • Partners must sign similar agreements, and must agree to safeguard the tools and information that will be provided to them. • Partners who are given access to Performance Engineering’s tools and data must agree to provide regular and timely feedback regarding the quality of the tools and information they receive.
Access Process • Partner Manager and local TC must nominate the resource and be the contact point if the Partner resource needs support from EMC SPEED and USPEED resources. • Partner Resource must of signed and returned an NDA. • Send Nomination form to ASNProgramOffice@emc.com • Once materials have been reviewed the partner resource will send an email to request the SPEED or USPEED exam • All exams received at the above email address will be reviewed by Engineering with results communicated back to the candidate by email • Upon successful completion of the exam Partners will be listed as SPEED and USPEED members and receive access to content via the eRoom
About the Exam The entrance exam exists for several reasons • The test is as much a learning experience as the reading • Every question is relevant to storage performance • Even the wrong answers are important • We want you to know what is not true • This is our way to dispel some misconceptions about performance • It is an open-book test and each section indicates which part of the required reading is necessary to pass it
Champions eRoom PMAP • We will use an eRoom to distribute PMAP content • https://eperoom02.emc.com/nsepn/webapps/ljxxqewdc7827657968xmymn46817756/eRoom/mrktng/EMC-PartnerChampionProgram • After submitting the nomination form and passing the test access to the USPEED or SPEED content will be provided
VNX Performance Training Material • New training material now available • VNX Performance Fundamentals • VNX Performance Architecture • VNX Performance Tuning • VNX Unisphere Analyzer • Parity RAID and Alignment
Pool LUNs allow us to distribute I/O over many disk drives Locality will determine if a burst of access to any one Pool LUN is absorbed by all the shared drives Pool LUNs will be built from private LUNs on private RAID groups This is ideal for ease of use Allocates slices of 1GB per private RG to build out user LUNs Supports thick LUNs Each 1GB is mapped to a 1GB logical block address of the user LUN Supports thin LUNs Each 1GB is divided into separate 8KB mapped logical block regions Best for random workloads Although thin LUNs will incur additional overhead for random writes for initial data placement TRAINING EXAMPLE - The Geometry of Performance Pool LUNs Unallocated slices Pool LUN: 500 GB Private RG 1 Private RG 2 Private RG 3 Private RG 0 Pool LUN: 750 GB Allocated slices Pool LUN: 250 GB 1GB slices will be allocated on demand, even for thick LUNs. The idea is that you’ll gradually consume private resources but balance your allocation per user LUN across all balanced pool resources automatically Pool LUN: 400 GB
VNX Performance Report Examples • VNX Block Scaling • VNX to CX4 Comparison • VNX File Scaling
HE 8KB 100% Read 32 thr R5 Random This profile gives us an idea of scaling to array limits for disk access Actual measured to 440 disks on the VNX5700 and 920 disks on VNX7500 281 IOPs per drive 197 IOPs per drive The 70% disk scaling line shows where disk utilization would be lower, however we also show the ROT line that should be used for sizing to ensure good response times and component utilization, allowing head room for activity bursts, replications ROT 180 IOPs per drive Adjusted VNX7500 data
Do not forget! • Charts denote maximums at stated disk counts • These will have high response times • Forced flushing if writing • Use estimated sizing of 70% top end, or stick with ROT calculations observing scaling capabilities for profiles shown
HE VNX to CX4 8KB 32thr Random 2R:1W Non-adjusted VNX7500 data
VNX to CX4 Comparison Summary • At low disk count, being disk bound, small block random performance comparable between all models • VNX scales much better to higher and maximum disk counts • CPU and memory speed improve aggregate bandwidth capabilities to 5x in some profiles • Increases bandwidth sweet spot to higher disk counts relative to model • Expect replication, both local and remote, to scale much better
Performance Summary • The VNX results in this presentation were based on 15K RPM SAS 3.5” HDD. Scaling results for Flash drives are pending and are expected to show improved performance at lower drive counts • VNX Series achieves 2-5x the performance in many workloads when compared to previous generation Unified Storage • With random workloads, we see consistent scaling from lower to higher end VNX systems due to increased drive count and faster CPU’s • With sequential workloads, the performance improvements have increased so much that we now see the Storage Processors consistently push physical component limitations. Opening up more opportunities in high bandwidth applications
