This week, I am in Orlando, Florida for the [IBM Technical University], with focus on IBM storage, IBM Z mainframes and IBM Power servers. This is my recap of afternoon breakout sessions on Day 2.
- Spectrum NAS 101 and key use cases
Chris Maestas presented IBM's latest addition to the Spectrum Storage family of Software-Defined Storage. Spectrum NAS was written from scratch in C/C++ language, instead of using open source code like SAMBA. It supports both NFS and SMB protocols.
Like IBM Cloud Object Storage, the Spectrum NAS software is shipped with the operating system, so you have a single ISO to run everything. You start with four nodes and can grow capacity and performance as needed by adding more nodes. All nodes have identical roles.
All of the storage is internal. Spectrum NAS uses DRAM memory, NVMe-based Solid State Drives (SSD), and spinning disk HDD. The NVMe drives must support at least five Drive Writes per Day (DWPD).
Each Spectrum NAS node can handle 2,000 connections, and up to 4,000 connections during fail-over processing. With 10GbE bandwidth, you can migrate 100 TB/day from other NAS devices to Spectrum NAS. If you want to try out Spectrum NAS yourself, there is a 60-day free trial offer now available. There are a collection of videos on the [Spectrum NAS YouTube channel] to walk you through the installation process.
- Clients are Hyper for Hyperconverged
Marc Richardson and Bruce Jones, both from IBM Cognitive Systems, presented this client case study on successful deployment of IBM Hyperconverged Systems powered by Nutanix, often referred to as the "IBM CS" models of the POWER server line. The covered three use cases:
- Modernize to Private Cloud
IBM CS models use the Nutanix Acropolis Hypervisor (AHV) to run Ubuntu and CentOS little-Endian virtual machines on POWER. The speakers claimed that they can run 50 percent faster, and 88 percent more workloads per core, than traditional x86 methods. IBM has made statement of direction that IBM CS models will support AIX 7.2 virtual machines later this year.
The IBM CS models can also run IBM Cloud Private, a collection of software that supports Docker and Kubernetes.
- Simplify the Data Center
The client was not happy with the high prices of their external, high-end storage systems. When you add another IBM CS models to the cluster, you get more storage capacity and CPU capability at the same time, in lock step. What could be simpler?
- Infrastructure for Modern Data Workloads
IBM CS models can run traditional Db2 and WebSphere applications. The client also reduced their costs by switching from expensive Oracle databases to open source databases like MongoDB and EnterpriseDB Postgres.
- Poster Session
I was honored with being selected for this week's poster session. I was poster 16, explaining the What, Why and How of IBM Cloud Object Storage. Here is am posting with my colleague Heather Allen, IBM.
Kelly Groff, IBM FlashSystem, had poster 15 on how the embedded compression on the latest FlashSystem 900 models have almost no performance impact. Jeff Barnett, IBM, had poster 14 for IBM's Pay-as-you-grow Storage Utility Pricing.
Barry Whyte drew large crowds with his poster 13 on NVMe. Andy Kutner, IBM, had poster 11 on IBM Cloud Object Storage.
Fahima Zamir, IBM, had poster 29 on VersaStack solution, which combines best-of-breed x86 servers and switches from Cisco with IBM storage into a converged system. Sharie Mims from VSS is an IBM Business Partner.
