In the HPE Nimble HF-series storage system, RAID 6 with triple parity is the default RAID setup, which uses 18 data drives for RAID stripes. RAID 6 provides high redundancy by allowing for the failure of up to two drives without data loss, making it an ideal configuration for environments that require a balance between performance, capacity, and fault tolerance.

HPE Storage Best Practices

In HPE StoreOnce environments, the two most commonly used file protocols are CIFS (Common Internet File System) and NFS (Network File System).

CIFS: This protocol is widely used in Windows environments for file sharing. It enables users and applications to access files on remote servers as if they were local, making it ideal for integration with Windows-based systems.

NFS: This protocol is commonly used in Unix and Linux environments for file sharing. It allows a user on a client computer to access files over a network much like local storage is accessed.

These protocols are integral to HPE StoreOnce's capability to provide flexible and efficient file-based backup and recovery solutions across different operating environments.

To integrate HPE 3PAR StoreServ arrays into an HPE OneView environment for automated volume provisioning, the installation of the 3PAR Host Explorer is required. The 3PAR Host Explorer software facilitates the communication between the HPE 3PAR StoreServ storage array and the OneView management platform. This software collects detailed host configuration information, which is then used by HPE OneView to optimize the management and provisioning of storage resources, ensuring that the storage is allocated correctly according to the system requirements.

This integration allows for better automation, management, and monitoring of the storage environment, thereby improving efficiency and reducing the likelihood of manual errors.

HPE 3PAR StoreServ Information

To support the deployment of HPE 3PAR StoreServ with 16GB/s Fibre Channel (FC) in an existing environment that includes HPE BladeSystem with Virtual Connect Flex-10 and ProLiant Gen8/Gen9 servers, the appropriate products to include are:

HPE B-Series 16GB SAN switch: This switch is necessary to provide the high-speed 16GB/s FC connectivity between the BladeSystem and the 3PAR StoreServ array, ensuring that the performance issues are addressed with minimal changes to the environment.

HPE 16GB/s Fibre Channel HBA for Blade servers: The FC HBAs (Host Bus Adapters) are required for the blade servers to connect to the 16GB/s FC SAN, enabling end-to-end high-speed connectivity from the servers to the storage array.

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.

The HPE Alletra 6030 storage system supports up to two 2140 4U All-Flash Array expansion shelves. These expansion shelves allow the system to scale up its storage capacity while maintaining the high performance and reliability expected of the HPE Alletra 6030 platform. The system is designed to provide flexibility in configuration, ensuring that it can meet the varying capacity requirements of enterprise environments.

HPE Storage Expansion Options

When adding a new virtual volume on an HPE 3PAR StoreServ array, the minimum required information includes:

Size: The size of the volume must be specified to define how much storage will be allocated.

CPG (Common Provisioning Group): The CPG defines the storage pool from which the space for the new volume will be allocated. It is essential to specify this to ensure the volume is created with the correct provisioning settings.

Other options like Persona type, Domain, and Host are additional configurations but not mandatory for the initial creation of the volume.

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.
