DST
Introduction
•Supports the file system of multiple volumes,
which means a single file system can span
different tiers.
•Automatically calculates file access frequency.
Frequently accessed files are automatically
migrated to high-performance hard disks, and less
frequently accessed files are automatically
migrated to cost-effective hard disks with large
capacities.
•Dynamically migrates files according to a preset
time policy and access frequency.
Technical Advantages
•Hotspot data is stored on high-performance
online storage media such as Fibre Channels
disks and SAS disks.
•The less frequently accessed data and unused
data are migrated to nearline storage media such
as SATA disks.
•The demoted data is directly accessed from the
cost-effective storage media and transparent to
applications.
•The data can also be promoted from the
secondary storage to the primary storage.

File system mirroring
Introduction
•
The N8500 file system supports mirroring. One plex includes at least 2 mirrors, and each mirror consists of subdisks that
belong to different virtual disks. Therefore, when data blocks are written into the file system, they are written into two mirrors
and eventually onto two physical disks.
Technical Advantages
•
Data is simultaneously written into two or three storage units. In this way, two or three file system mirrors are formed. If a
single storage unit becomes faulty, services are not interrupted. This ensures high availability of the customer service system
and saves the cost for establishing an individual disaster recovery center.

Technical principles of file system snapshot
Data space of the file system
Data blocks on disks
Reserved snapshot
space
File system snapshot (copy on write)
•A snapshot is created for the file system for the first
time.
•The snapshot contains block mappings that
point to the file system.
•The block mappings point to the data in the file
system.
•The snapshot is logically identical to the file
system.
•Data blocks are updated for the first time.
•Original data blocks are copied to the reserved
snapshot space.
•The block mappings in the snapshot point to the
data blocks in the reserved snapshot space.
•Data blocks are updated for a second time.
•New data is directly written to the file system.
Technical Advantages
•Snapshots can be shared with the service host.
•Snapshots can be accessed or copied.
•It takes only a few seconds to create a complete
snapshot.
•Snapshots consume only a small portion of storage
system space.
•File system recovery, backup, testing, and data
analysis are supported.

File system remote replication
The N8500 supports asynchronous remote replication.
Data is synchronized periodically to minimize the
adverse impact on service performance caused by
long-distance transmission latency.
Clients

Technical Advantages
Tracks data block changes, boasts high transfer
efficiency, and provides stable performance as the
number of files grows.
Occupies no N8500 engine resources.
Has no requirements on the number of protected
N8500 NAS
engine
files and directory depth.
Technical Principles
N8500 NAS
engine
N8500 storage
unit
After receiving a client write request, the N8500 writes
the data into the primary LUN of a storage unit. When
Asynchronous
remote replication
Primary site
a synchronization period ends (a synchronization
period is customized and ranges from 30 to 1440
minutes), a synchronization task is initiated,
automatically enabling all data on the primary LUN in
a consistency group to be incrementally synchronized
to the secondary LUN.

Quota management

Soft quota and hard quota

Hard quota refers to a real limit on the space.
If the limit is exceeded, data loss occurs.

Basic process
Soft quota refers to an agreed limit on the
space, which is not mandatory and lower
than the hard quota. When the used space
approaches the quota limit, the user is still
allowed to modify data. The soft quota time
limit of the N8500 is 7 days.

User- and user group-specific quota

Allows setting a quota for storage space that
a single, specific user can use.


3. Check whether quotas are used up.
Note

4. Check whether data can be written.
The quota size cannot exceed the file system
size.
21
Domain environment
The N8500 supports multiple domain management modes such as Active Directory Services (ADS),
Network Information Service (NIS), and Lightweight Directory Access Protocol (LDAP).
CIFS-based permission management is achieved on the SAMBA
protocol layer.
Step

3. Receive a command request from the SMB
4. Respond to the request.
The client uses the user permissions to operate the

22
The SAMBA server responds to the client request.
File system WORM
File system WORM enables data on a file system to be read multiple times once being written,
preventing data from being tampered or misdeleted.
The N8500 WORM function is designed to ensure that users
invoke standard Portable Operating System Interface Standard
(POSIX) interfaces to operate files without changing the ways
N8500 node
users operate files.

module intercepts this operation to protect the file. If a user
wants to modify, delete, or move a file that is not in the WORM
protection state, the WORM subsystem transparently transfers

the operation to the file system.
The read-only property can indicate the WORM protection
state. The atime property is used to display the expiration time.
Users can set the WORM protection state and query the
expiration time by invoking interfaces.
23
NDMP backup
By integrating with third-party network data
management protocol (NDMP)-based backup software,
the N8500 provides backup and recovery features.
If a customer has installed NDMP-based third-party
backup software, the N8500 can directly integrate with it,
saving customers' investment.
NDMP V4 is supported.
The NDMP backup modes contain 2-way backup and
3-way backup.
File systems and directories on the N8500 can be
backed up and recovered.
Three backup types are available, full backup,
cumulative incremental backup, and differential
incremental backup.
Three recovery types are available, complete recovery,
Direct Access Recovery (DAR), and selective recovery.
Backup media can be virtual tape libraries (VTLs) and
physical tape libraries.
24
DMA is an application used to create and control NDMP
sessions. The client is responsible for accessing, storing,
and managing all sessions, server topologies, tape settings
and numbering, synchronization, for example, completely
or partially recovering a file system. A unique link exists
between the DMA and each NDMP server. This link is an
NDMP control connection, which is a bidirectional TCP/IP
connection.
DNS load balancing
The N8500 supports five load balancing policies.
Basic process
You can select load balancing policies based on
site requirements.

Notes

The performance evaluation results are calculated out in large-file sequential reads/writes
scenarios. They are used as references only and are not used for bidding or as performance
commitments.

Large-file sequential reads/writes scenarios are those where the file capacity is tens of
Megabytes and the NFS protocol is used.
27
N8500 performance computing methods

P1: Back-end storage unit performance = Performance of a single disk x Number of valid
disks (from which RAID group waste and hot spare disks are excluded)

P2: NAS engine performance = Performance of a single NAS node x Number of nodes x
80% (only when the performance of the back-end storage unit is sufficient)

Overall performance of the N8500 = Min (P1, P2)

P1: Storage unit performance cannot exceed the maximum performance limit of storage unit
controllers.

P2: Use this method to evaluate the performance if the quantity of nodes is smaller than four.

environment
Do not apply the N8500 to traditional
storage scenarios, such as Mail, SharePoint,
Notes, Office, Domino, and ERP.
Alternatively, use NAS as a file server to
allocate folders to each user.
The N8500 supports read, write, and delete permissions. Its
scalability is limited in a Windows environment. Enabling Full-ACL
will reduce the performance by 70%. To apply to multiple domains
or hybrid domains, consider using WSS + T series solution.
VM and
database
NAS runs in VMs or databases.
When running in a database or VM, NAS has a low compatibility,
and performance and data reliability may fail to meet requirements.
In this case, SAN is recommended.
Concurrent links
NAS storage space is provided for a large
number of PC users including web disk,
desktop cloud, and CallCenter users.
Each N8500 node supports 400 concurrent connections.
Customers require over 5 GB/s bandwidth.
Due to 4-node specifications constraints, the N8500 cannot deliver
5 GB/s bandwidth. For projects requiring over 5 GB/s bandwidth,
evaluate whether the OceanStor 9000 meets requirements case by
case.
