HPE Synergy Composer is the tool used to manage the HPE 3PAR StoreServ system when it is connected to a Synergy-based composable infrastructure via direct-attach. Synergy Composer is powered by HPE OneView and provides a unified interface for managing compute, storage, and networking resources within the Synergy environment. It allows administrators to manage the storage configurations, provisioning, and lifecycle management of the connected HPE 3PAR StoreServ system, ensuring seamless integration with the composable infrastructure.

For HPE GreenLake for Block Storage systems, particularly when equipped with two enclosures or cages, and considering a high availability (HA) level for drives, the maximum set size value that can be manually set is 6+2. This configuration means there are six data drives and two parity drives, ensuring that the system can withstand the failure of two drives while still protecting the data.

HPE Storage Availability and Performance

Synchronous replication is the data protection technology that offers the lowest possible Recovery Point Objective (RPO) and can protect against an entire array failure. Synchronous replication ensures that data is simultaneously written to both the primary and secondary storage sites, providing real-time data protection. This approach minimizes data loss in the event of a disaster, as both sites contain identical data, making it the best choice for environments where data integrity and minimal RPO are critical.

HPE StoreVirtual VSA’s Adaptive Optimization feature is ideal for addressing the challenge of intermittent heavy disk I/O in mission-critical applications. Adaptive Optimization dynamically adjusts the storage tiering based on real-time workloads, ensuring that the most frequently accessed data is moved to faster storage tiers like SSDs, without the need for manual intervention. This feature allows the customer to benefit from SSD performance when needed, without permanently dedicating SSD resources, thus optimizing both performance and cost.

HPE Storage Performance Features

A very low deduplication ratio in a Linux VM farm hosted on an HPE Alletra 9000 could be caused by the use of the XFS filesystem. XFS is known for its performance and scalability but is less effective in environments where deduplication is critical because of its data layout and file handling characteristics. This can lead to reduced deduplication efficiency compared to other filesystems like EXT4 or Btrfs.

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.

To calculate the required capacity for snapshots after one week for an HPE Alletra 9000, we start by understanding the customer’s requirements:

Base volume size: 100TB

Snapshots: 168 snapshots per week

Daily change rate: 15%

The snapshot capacity requirement can be calculated by taking 15% of the base volume size per day, and multiplying it by the number of days (7 days in a week) and the number of snapshots per day.

Daily change: 15% of 100TB = 15TBTotal change over a week: 15TB * 7 days = 105TB

Thus, the capacity needed for snapshots after one week is 105TB.
