Managing Hitachi NAS Platform file systems and sharesThis module describes how to create file systems and shares for Hitachi NASPlatform (HNAS) file servers.
About managing Hitachi NAS Platform file systems and shares The Hitachi NAS Platform family (HNAS) provides high performance fileserver capabilities using storage system volumes.
The Hitachi NAS Platform family (HNAS), managed using Systems
Management Unit (SMU), includes the following models:
• Hitachi NAS Platform 3080/3090 • Hitachi NAS Platform...

• Add file sharesYou can add file shares (CIFS Share or NFS Export) to file systems with
adequate free capacity for your purpose. If a file system does not have
adequate free capacity, it may be possible to expand the file system (see
below). A license related to file sharing functionality for file servers is
required.
• Expand file systems
You can use  Top 10 File Systems  from the dashboard to check for file
systems with a high capacity usage. If a file system is at risk of not having enough free...

• File systems whose allocation type is Full Allocation should be expandedmanually. When expanding a file system, specifying a capacityimmediately allocates that capacity to the file system.
• Expand storage pools You can use  Top 10 File Server Storage Pools  from the dashboard to
check for storage pools with a high capacity usage. If a storage pool does
not have sufficient free capacity, allocate volumes (system drives) to the
file server by using Device Manager to expand the storage pool.
If you are...

Workflow for providing NAS Platform file shares Use Device Manager to create files systems and files shares (CIFS or NFS
Export) when a Hitachi NAS Platform file server is managed using System
Management Unit (SMU) v10.1.3070 or later.Tip:  When a file server is managed by an SMU version earlier than
v10.1.3070, first allocate volumes to the file server by using Device Manager,
and...

By setting Device Manager information in SMU, file server information
managed in SMU is sent to Device Manager to register file servers to be managed by Device Manager.
• Set Admin services EVS For Hitachi NAS Platform v10.2.3071 or later, using Device Manager, set
Admin services EVS information (IP address and user account for the
Server Control (SSC) of the file server) for each cluster.
• Create a storage pool Hitachi NAS Platform manages system drive volumes that are allocated toa file server and...

Best practices for configuring storage poolsThis topic describes the best practices for configuring storage pools tomaximize the performance and reliability of Hitachi NAS Platform and toefficiently use as much of the storage capacity as possible.
Storage pool configuration greatly affects performance, reliability, capacity efficiency, and expandability of file systems used. Follow the best practices
suggested by Hitachi NAS Platform for creating or expanding a storage pool.
Following is an overview of...

better performance. Large chunk sizes have better expandability but
compromise performance.
If linking with Hitachi NAS Platform v11.3 or later, Device Manager automatically creates or expands a storage pool with the optimum
configuration based on best practices. You just need to select parity groups
that meet the conditions. You do not need to configure volumes, paths, or
settings for writing to system drives.

free capacity of the storage pool. Therefore, the actual file system capacitydiffers from the value of Guideline Capacity.Tip:  If you are using a version of Hitachi NAS Platform prior to v11.2,
consider the following recommendations:
• Create a chunk size of 1 GB or more.
• The size of a created chunk may not match the specified size. If you create a file system by using a storage pool that has this chunk size, the capacityof the file system also may not match the value of  Guideline Capacity.

Prerequisites
• For cluster configurations, identify the name of the target cluster • For non-cluster configurations, identify the name of the target file server
• For creating a storage pool, identify settings such as the storage pool name and capacity
• The file server must be registered in Device Manager
• Device Manager must be linked to Admin services EVS
• To improve performance, reliability, and capacity efficiency of storage pools, set conditions for parity groups that are used in storage pools....
