HPE 3PAR Peer Motion, combined with the SSMC (StoreServ Management Console), is the optimal solution for a customer who needs to move workloads between different HPE 3PAR StoreServ arrays within the same data center. Peer Motion allows for seamless and non-disruptive data migration across different arrays, enabling the customer to optimize performance by moving workloads to the most appropriate storage tier or array as needed. This capability ensures that the storage environment remains flexible and responsive to changing performance demands.

HPE SSMC Overview

Given the shift to a read-intensive workload, adding a tier of SSD (Solid State Drives) will significantly improve the read I/O performance of the environment. Implementing thin provisioned virtual volumes allows the storage to be allocated more efficiently, optimizing the use of available SSD resources. This combination ensures that the customer can meet the new performance demands without overspending, making it the best option for a budget-restricted scenario.

The NAND memory controller is the component responsible for wear leveling in SSDs. Wear leveling is a process used to extend the lifespan of NAND flash memory by ensuring that write and erase cycles are distributed evenly across the memory cells. This prevents any single cell from being overused, which could lead to premature failure. The NAND memory controller plays a crucial role in managing this process, ensuring the reliability and longevity of the SSD.

The performance alert command provided would trigger an alert if an array port has received more than 10,000 write IOPS or if the sum of all write IOPS for all ports exceeds 50,000. This alert is designed to monitor and respond to high I/O activity on the storage array, ensuring that administrators are notified if the performance thresholds are breached, which could indicate potential issues or the need for further resource optimization.

NPIV (N_Port ID Virtualization) is the feature that needs to be enabled on B-series FC switches to allow individual virtual servers to have independent storage access. NPIV allows multiple virtual machines to share a single physical Fibre Channel port while maintaining separate identities (N_Port IDs), enabling each virtual machine to be seen as a separate entity on the SAN. This is crucial in a virtualized environment where individual virtual servers need direct storage access.

When using a federated storage approach with HPE 3PAR StoreServ systems, customers can benefit from:

Load Balancing: Federated storage enables the distribution of workloads across multiple storage systems, optimizing resource utilization and ensuring that no single system becomes a bottleneck. This load balancing improves performance and enhances overall system efficiency.

Easier Migration: Federation simplifies the process of migrating data between storage systems. With features like Peer Motion, data can be moved between systems non-disruptively, allowing for seamless upgrades or expansions without impacting ongoing operations. This capability is particularly beneficial in reducing downtime and maintaining business continuity during migrations.

The Persistent Cache feature provides the benefit of automatic write cache mirroring in the event of a partner-node failure. This means that if one node in a high-availability setup fails, the write cache data is still protected and mirrored on the surviving node, ensuring data integrity and continuity. This feature is crucial for maintaining the high availability and reliability of storage systems in mission-critical environments.

Before expanding an HPE 3PAR StoreServ 8400 system with additional nodes and disk enclosures, it is essential to update the system to the latest supported OS. This ensures compatibility with the new hardware and access to the latest features and improvements. Running the latest OS version also mitigates potential issues during the hardware expansion process, providing a stable and supported environment for the new nodes and enclosures.

When adding additional SSDs to the HPE 3PAR StoreServ 8200 with an existing RAID5 7+1 configuration, it is advisable to reconfigure the CPG (Common Provisioning Group) setsize to RAID5 5+1. This reconfiguration will allow the array to better balance the additional drives and optimize the use of available storage. After changing the setsize, running tunesys will ensure that the data is redistributed across the new set of drives, optimizing performance and availability.
