As I look at customer environments, there is a growing interest in IP-based storage technologies. In my testing NVMe/TCP vs FC, particularly in 25Gb IP vs 32Gb FC, is roughly equivalent, and is significantly more performant than iSCSI. Development of NVMe/TCP shows leadership in this space.
NVMe over TCP/IP on IBM Power Systems is the key technology to enable the usage of Ceph storage for PowerVM VIOS Server installations.
What does IBM Storage Ceph 7.1 offer as new option?
Fast network-based Block storage for VMware, OpenShift Virtualize, Proxmox (KVM) and PowerVM VIOS.
IBM Storage Ceph 7.1 offers NVMe/TCP access to Ceph (RBD) block storage.
NVMe/TCP enables access to Ceph RBD block storage. This functionality enables VMware vSphere to connect with IBM Storage Ceph and use Ceph block storage as VMware VMFS storage resourcing. The methodology looks similar in scope and design to Ceph RBD over iSCSI in the past. However, this is a complete new management layer via a Ceph-NVMe/TCP daemon. This deamon coordinates configuration of NVMe/TCP targets, across multiple cluster nodes, including fail-over capabilities.

IBM Power Systems have traditionally been known for their high-performance computing capabilities and reliability. NVMe over TCP/IP (NVMe-oF TCP/IP) is a technology that allows NVMe storage devices to be connected to IBM Power Systems and other platforms over standard TCP/IP networks. Here are some justifications for using NVMe over TCP/IP on IBM Power Systems:
High-Performance Storage: NVMe (Non-Volatile Memory Express) is a protocol designed for flash storage that offers extremely low latency and high throughput. By using NVMe over TCP/IP, IBM Power Systems can take advantage of this performance, making it ideal for applications with high I/O requirements, such as databases, analytics, and AI workloads.
Scalability: TCP/IP networks are widely deployed and offer scalability. NVMe over TCP/IP allows you to scale your storage infrastructure as your needs grow without major infrastructure changes. This is crucial for businesses that want to expand their storage capacity or performance without extensive reconfiguration.
Shared Storage: NVMe over TCP/IP enables shared storage solutions, which is essential for virtualization and clustering technologies, including IBM PowerVM and IBM PowerHA. These technologies require shared storage to ensure high availability and seamless failover.
Compatibility: NVMe over TCP/IP can work with existing Ethernet infrastructure. It doesn't require specialized network hardware. This makes it easier for organizations to adopt this technology without major investments in new network equipment.
End-to-End Security: NVMe over TCP/IP can leverage existing security features of the TCP/IP protocol stack, including IPsec (IP Security), to ensure data integrity and confidentiality. This is especially important for businesses that deal with sensitive data.
Simplified Management: NVMe over TCP/IP leverages the management capabilities of the Power Systems platform, allowing for unified management of storage and compute resources. This simplifies administration and reduces operational complexity.
Multi-Platform Compatibility: NVMe over TCP/IP is not limited to IBM Power Systems. It is a standardized protocol that can be used with various platforms, making it a versatile and future-proof solution.
Cost-Effective: As it can utilize existing Ethernet infrastructure and is compatible with various storage solutions, NVMe over TCP/IP can be a cost-effective choice for organizations looking to boost their storage performance without excessive expenditures.
Future-Proofing: The NVMe protocol is widely adopted and continually evolving, making it a future-proof choice for organizations that want to stay at the forefront of storage technology.
In conclusion, NVMe over TCP/IP on IBM Power Systems provides high-performance, scalability, compatibility, and security, making it a compelling choice for organizations seeking to optimize their storage infrastructure while maintaining or improving their existing IT investments.
