A way to improve the Netapp storage performance?
There’s no direct declare this question however we have a tendency to shall love in many method.
If volume/lun gift in ATA/SATA hard disk mixture, then the amount are often migrated to FC/SAS disk mixture. Either you’ll be able to use flash cache to enhance performance.
For NFS/CIFS rather than accessing from single interface, multi mode vif are often organized to induce higher information measure and fault tolerance.
Forever suggested to stay aggr/vol utilization below ninetieth.
Avoid doing multiple volume backup in single purpose of your time.
Unable to map lun to solaris server, however solaris server aspect no issue. A way to resolve the issue?
FROM STORAGE SIDE:
Verify iscsi/fcp license is additional in storage
Verify iscsi/fcp session is logged in from server aspect use below command
Netapp> igroup show -v
Verify luns square measure mapped to the corresponding igroup
Verify whether or not correct host kind is mentioned whereas making igroup and lun
Verify whether or not correct iqn/wwpn range is additional to igroup
Verify partition is correctly organized from switch aspect, if it’s FCP protocol

The way to increase the volume?
ancient Volume
vol add VolName no.of.disk
Flexible Volume

What’s qtree?
qtree is Logical partition of the amount.
What’s the default snap reserve in aggregate?
5%
What’s snapshot?
A shot copy may be a read-only image of a standard or FlexVol volume, or AN combination, that captures the state of the filing system at some extent in time.
What square measure the raid teams Netapp supporting?, what’s the distinction between them?

3260
What’s the distinction between ndmp copy and vol copy?
Ndmp copy –network information management protocol(used for tape backup)
Vol copy – is employed to transfer volume to same or another mixture
Justify however De-Duplication works?
In the context of disk storage, De-duplication refers to any rule that searches for duplicate knowledge objects (for example, blocks, chunks, files) and discards those duplicates. once duplicate knowledge is detected, it’s not maintained, however instead a “data pointer” is changed in order that the storage system references a certain copy of the info object already keep on disk. This De-duplication feature works well with datasets that have countless duplicated date (for example, full backups).
