Log analysis tools can run on any PC, do not need to interoperate with the storage system, the analysis process time according to the amount of the log may be, may it takes a long time

Log Analysis Tools After starting the analysis, the analysis tasks need to be stopped due to other reasons. Click on the analysis tool to abort this analysis

Engineer A deleted the original compression of the results of the collection, then the results will be collected to re-catalog the contents of all documents compressed into zip format for the dayChi analysis tools for analysis

After the analysis is completed, all the problems caused by the log analysis will be presented in the list of problems, and "View Details" contains the approximate cause of the problem and processing advice

CIFS does not allow multiple clients to access

The CIFS client writes the shared file and does not write to the storage system immediately. Instead, the file is saved in the local cache and can be read againImprove read rate, improve performance

CIFS does not support anonymous transmission and shared authentication access

CIFS supports a variety of character sets to ensure CIFS can be used in all language systems

The types of quotas include capacity quota and file quota.

Quota methods include calculating quotas, soft quotas and mandatory quotas.

The system pre-allocates quotas for files before writing the file. When the user cancels the writing of the file being written, the system does not release a pre-allocated quota.

When the user continues to write data, the quota information has been used in the InfoAllocator interface real-time updates.

On the slots of the same position on both nodes, such as A3 and B3, you must insert the same type of interface card.

A5 and B5, A6 and B6 can be chosen to be networked, the key is howto make the network connections.

If the back end of the engine cluster is to be directly connected to four control enclosures, add one FC HBA card in slots A2 and B2 for the controller enclosure of direct connection.

A2, A3, A4 and B2, B3, B4 can beplugged into a 1Gb iSCSI or 8Gb FC interface module to connect with the business network.

It does not consume any host resources.

It is lower in migration cost than gateway-layer solutions such as those based IBM SVC, and EMC VPLEX.

It requires services to stop only once, and the service stopping occurs after the migration.

It delivers higher migration speed than host-layer solutions.

A client business IO load random read that accounts for more than 60% using SATA, SAS for staging storage, use SSD to do cache, so it will effectively reducecosts and improve random performance indicators

If hot spot data is scattered and changing rapidly, it is recommended to use tiered storage

If there are many SSDs and hotspots, Smart Cache is the best choice

If you have a small amount of SSD data,use a tiered storage disk for more utilization

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time

Disaster recovery data stored in the Cache, not yet written to the hard disk

When creating a snapshoton the disaster recovery end LUN The production end is copying data to the disaster recovery end

The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been recovered

With continuous random read: RAID 5 performance is superior to RIAD10

With sequential read and write, RAID 5 performance are better than RAID10

With sequential write, RAID10 better than RAID5 performance

With continuous random read, RAID 5 and RAID 10 performance is equal.

Multiple LUNs for Customer Business. When implementing data migrationusing remote replication, you need to add multiple remote replication tasks to a consistency group

Use remote replication to complete online data migration

LUN copy or remote replication. After the migration is complete, you do not need to do any configuration on the host to start the service

LUN copy data migration. During the copy process, you can dynamically change the migration rate

Not just the host with IP 100.43.13.210 can access this NFS share

Toquery the client for all the NFS shares on the service IP, use the command: showmount -e 100.43.13.11

Mount the NFS shared file system locally and execute: mount -t nfs 100.43.13.11:xs-cmfs / mnt

Verify that NFS shared file system has been mounted locally, executable: mount

Use the mount command to view the file system mount status is read-only

5 devices TOE NIC A0, B1, and A0, B3 inserted into the PCIe slot will not affect the system. Deployment will not affect the network bandwidth, so it cannot be adjusted.

The signal cables are long and need to be strapped to the cabinet or placed on the bottom tray.

Label NODE 01 A0-0 The signal cable is inserted in the network port A0-1. The signal cable labeled NODE01 B3-1 is inserted in the network position B3-0, due to the same network card two network port peer, you can place the wrongline, you cannot adjust.

The storage is connected directly to the virtual machine, including RDMs, directly to iSCSI or NFS.

Virtual machines contain large databases.

The virtual machine is deployed in the AIX operating system.

Virtual machines contain non-Microsoft family applications.

Support for SMB3 multichannel features that take full advantage of client-side multi-core CPUs and bandwidth resources to dramatically improve performance.

When a hard drive has multiple objects at the same time to write requests, support merged into a large continuous IO, significantly improve system performance.

Pause the app before the snapshot, go to the hardware storage snapshot to trigger a common snapshot with application consistency.

Backup software snapshot function can automatically find the storage volumeof the file system, database, mail system.

Background snapshots can be indexed to ensure application recovery and small particle recovery.

Snapshots backup can be offline, the backup server almost has no impact.

Restore (restore) refers to the previously generated backup set, get one or more objects, and then set to restore these objects.

Recovery (recovery) is a database that is consistent with the given point in time to ensure that thisdatabase can be opened.

Usually restored content lags behind the latest database SCN, so you need to ensure consistency through the restoration of the database.

The restored data files can use archived logs and online logs to complete the recovery.

When configuring thebackup client on the VTL side, you need to know that the WWPN of the FC port that connects the VTL to the VTL is available on the server in the sys /class / fc_host directory and subdirectory to the corresponding WWPN port.

Server-side identification has been detected with the library device command is cat / proc / scsi / scsi.
