Solving the Challenge of Sluggish Data 3X faster small file access 12X faster epoch times 2x faster modal training “ WEKA running in Cloud is game- changing for us. We’re able to run experiments in less than a week instead of three months or more. ” Jon Sorenson, PhD, VP of Technology Development, Atomwise 

GPU Clouds 

GPU Cloud "WEKA is the only data platform that delivers the speed, scale, and simplicity required by large-scale GPU clouds.” - Cory Hawkvelt, CTO NexGen Cloud 

GPU Cloud "...One of the things I think WEKA excels at, is they deliver really, really quick data to those GPUs so that they can be utilized to the max.” - Mike Maniscalco, CTO Applied Digital 

Confidential Embargo Notice The following two sections of this presentation are under embargo and strictly confidential until made public Embargo dates are marked throughout - or will be confirmed by WEKA later next week. 

IT Press Tour Exclusive: Performance Benchmarks Confidential: Under Embargo Until March 14. 

Performance overview • WEKA’s “zero-tuning” architecture is highly performant across all types of IO. • Massive parallelization of all data and metadata operations • Use of kernel bypass technologies • Patented data layout, protection and more • Software defined allows it to run on-prem or in the cloud • Flexibility to use any hardware (physical or virtual) and utilize latest clients • Rapid adoption of new HW as needed • Performance Benchmarking strategy • Use published, audited, repeatable and transparent benchmarks to show performance leadership • Performance may be raw #, synthetic metric ($/IOP, #jobs/TB, #cores/GB/sec, etc), efficiency, and more • Mix On-prem with cloud benchmarks to showcase flexibility Confidential: Under Embargo Until March 14. 

Results Benchmark Infrastructure Target Results SPEC_ai_image Azure 64x ls8v3 backends and 16x d64sv3 clients Show efficiency in Azure for AI workloads Beat Qumulo SPEC_ai run by 175% in raw performance, while only being 64% of the infrastructure cost. When a latency factor is put in, WEKA effectively can do 2.5x the number of jobs in the same time that Qumulo takes, and our effective cost per job is only 25% of Qumulo. SPEC_ai_image AWS 40x i3en.24xlarge backends and 40x c5n.18xlarge clients Dominate Qumulo result, #1 position in category 6x higher load count than Qumulo. Infrastructure costs impacted the effective cost per job, but still only76% the cost per job of Qumulo. Big or small, in multiple clouds, WEKA is faster and has a better cost-per-job than a competitor. #1 result SPEC_eda_blended AWS 40x i3en.24xlarge backends and 40x c5n.18xlarge clients Beat NetApp on-prem result. #1 position in category NetApp:6300 jobs at 1.39ms ORT. WEKA in AWS: 6310 jobs at 0.87ms ORT. WEKA is 60% faster response time. In the cloud. Against the NetApp fastest 8-node on-prem system they've got (A900 NVMe). Effective result is that WEKA can process over 10,000 jobs in the same time they can do 6300. #1 result Confidential: Under Embargo Until March 14. 

Results Benchmark Infrastructure Target Results SPEC_vda AWS 40x i3en.24xlarge back ends and 40x c5n.18xlarge clients #1 position in category WEKA still owns the #1 spot from 2 years ago. (8000 streams) We beat it with 12000 streams. On-prem or in cloud, WEKA is the highest performing video platform around. #1 result SPEC_genomics AWS 40x i3en.24xlarge back ends and 40x c5n.18xlarge clients #1 position in category No direct competitor in category, so take over #1 spot from niche DAS player (UBIX technology). 2200 jobs achieved for the #1 result SPEC_swbuild AWS 40x i3en.24xlarge back ends and 40x c5n.18xlarge clients Beat NetApp, #1 position in category Raw, WEKA achieved 3500builds with a ORT of 0.74ms. So, #2 overall. BUT WAIT... NetApp 8-node A900 NVMe system did 6120 builds at 1.58ms ORT. WEKA's advantage of being ½ the latency means an effective 7472 builds in the same time. So, we have an effective #1 result. Confidential: Under Embargo Until March 14. 

Performance Summary § Effective cost leadership in the cloud for AI workloads, Ability to scale up for AI workloads as needed § Overall performance against ANY workload with no ongoing tuning (Placement groups, number of FE’s) § Metadata/mixed IO/latency performance matters: It’s not just about throughput § Cloud Performance that can beat On-Prem § #1 in all SPEC categories, whether it's a raw number or effective# • Futures • STAC-M3, ML-Perf, STAC-ML, IO-500 and others • Mix of cloud and on-prem benchmarking including WEKApod base config. • Transparent, publicly documented and repeatable synthetic results (FIO, El Bencho, VDbench, etc.) Confidential: Under Embargo Until March 14.
