Sizer Sprint Release Announcement (22 Apr 2025)
Hello Sizer Users,
We’re thrilled to bring you the latest updates from our April 2025 sprint! This release focuses on enhancing your flexibility, optimizing storage efficiency, and expanding our support for modern infrastructure and AI workloads. Here’s a breakdown of the key improvements:
Key Features & Enhancements:
1. Enhanced Disaster Recovery with Zero Compute MST:
- Now, you can leverage the cost-effective Zero Compute deployment mode for remote snapshots via MST. This allows you to replicate snapshots directly from your on-premises clusters to object storage.
- Nutanix Objects Support Extended: Configure remote snapshots via MST for Nutanix Objects in both Pilot Light and Zero Compute deployment modes. (Note: Nutanix Objects cluster sizing is currently manual).
- Benefit: Achieve a more efficient and cost-effective disaster recovery strategy for your critical data.
2. More Accurate Power Planning for HPE DX Solutions:
- We’ve updated the power requirements and PSU recommendations for HPE DX solutions to provide greater accuracy in your BOM.
- Power calculations now assume fully populated memory and drive configurations for a given platform.
- Important Note: Power requirements may vary if your configuration differs from fully populated memory and drives. Chassis, CPU, and GPU power requirements are based on actual HPE wattages. Other component estimations are detailed below:
- Memory: 5W per DIMM
- Drives: HDD (10W), SATA SSD (5W), SAS SSD (18W), NVMe (20W) per drive
- NIC: 10W per card
- Benefit: Plan your HPE DX deployments with more confidence and accuracy, ensuring you have the right power infrastructure.
3. Optimize Storage with Wide Stripping Support:
- Sizer now supports wider striping options (6D, 2P & 8D, 2P) for Files and Objects use cases.
- Sizer intelligently considers these new options to automatically determine the most storage-efficient strip size for your workloads.
- Coming Soon: In a future release, Sizer will display the automatically selected strip size, providing even greater transparency.
- Benefit: Maximize your storage utilization and efficiency for Files and Objects deployments.
4. Accelerate AI Initiatives with GPT-in-a-Box 2.0 Reference Scenario:
- A new “GPT-in-a-Box 2.0” reference scenario is now available in the AI section.
- This comprehensive scenario provides solution sizing for:
- NKP Management Cluster
- Control Plane & Worker Node Pool
- NKP NAI – Managed Workload Cluster (GPU Node Pool, Control Plane & Worker Node Pool)
- 10 TB of Files for GPT offering & Objects Worker Nodes
- Scale-out Prism Central
- Benefit: Streamline the sizing process for your GPT-in-a-Box 2.0 deployments, accelerating your AI initiatives.
5. Introducing Early Access to Licensing by Cluster:
- We understand that multi-cluster environments have varying licensing needs.
- We’re excited to offer early access to our new “Licensing by Cluster” feature!
- Important: This is an opt-in feature and is not yet available to all users. Some minor updates are still in progress.
- Call to Action: If you’re interested in exploring this new capability, simply comment “License by Cluster” below, and we’ll grant you access.
- Benefit: Gain more granular control over licensing in your multi-cluster deployments.
Improvements:
- NUS Licensing Option: The licensing dropdown now includes the option to select the NUS license.
- Data Lens Premium: The ‘Data Lens Premium’ add-on option is now available when the NUS license is chosen.
- Flexible Prism Central Sizing: You can now specify the exact number of PC instances required when manually configuring the PC management cluster. @rob.buchanan
- Simplified Manual Node & Component Editing: Easily adjust the quantity of nodes and components in manual mode using intuitive “+” and “-” buttons, similar to the automatic mode.
- Nvidia H100 NVL GPU Support: The Nvidia H100 NVL GPU is now supported on the NX-3155-G9 model.
- VMware Horizon Renamed: “VMware Horizon” has been updated to its new name, “Omnissa Horizon.”
New Models Launched This Month:
- NC2 on AWS: i7i.metal-24xl, i7i.metal-48xl, i7ie.metal-24xl, & i7ie.metal-48xl
- Dell XC7625-24N
