What is the Reason for Exchange 2010 deduplication issues

Exchange 2010 deduplication issues You create a Volume size – 100GBs. You present a LUN to the Exchange Host of a 100GBs. The Exchange database resides on the 100GBs RDM LUN. The Exchange Host does not see the relationship between WAFL blocks and logical block volume. The relationship is being manipulated by deduplication and the Exchange Host only sees its RDM LUN File Allocated Table and its data. The host writes three files to the File Allocation Table RDM/LUN, file (A) 30GBs, file (B) 30GBs, and file (C) 30GBs that equals 90GBs. The Exchange Host see that it’s RDM LUN now has 10GB Free space. WAFL see the file (c) 30GBs as identical and only writes 60gbs of data to the volume. Therefore the Exchange database remains unchanged in size of 90GBs from the host’s perspective, even though there are capacity savings at the volume level. The 30gbs of claim space can be reallocated to the RDM LUN using SnapDrive. Click here for related Topics These White Papers... Read More →

Exchange 2010 deduplication issues

Deduplication issues NetApp dedupe at the block level, so if there are duplicate blocks, it doesn’t matter if they are in an RDM or a VMDK, they will get deduped. To us, it’s all just data. What does matter is how the LUNs are provisioned… If you are thick provisioned, deduping (reserve) won’t increase your efficiency. The LUN will still consume the same amount of space. At the end, both Volume and LUN will need to be Thin Provisioned. That said, with ISCSI data de-duplication gave savings on the Array however with NFS savings on the datastore. Thin Provisioning is supported on RDMs. Here’s the thing -- Deduplication is transparent to Exchange and the block changes are not recognized by Exchange. Therefore the Exchange database remains unchanged in size from the host’s perspective, even though there are capacity savings at the volume level. Here the assessment on thin provisioning Personally I like thin provisioning, but it is really... Read More →

Virtual Storage Through VSC/RCU Part II This article, in General, highlights the underling technologies that makes what VSC/RCU plug-ins do seem so easy. However, FlexVol Volume, FlexClone, Snapdrive and Snapshot Technologies makes VMWare and NetApp Storage Management Plug-ins capabilities possible. The RCU support deduplication (options to enable deduplication and report on it from within vCenter Server), NFS datastore resizing, creating/deleting/cloning block-based datastores, and support for basic role-based administration control (RBAC) in that user permissions are checked before tasks are launched. In addition, use of the RCU mitigates many of the drawbacks I’ve discussed in the past with regard to use array-based cloning in virtualized environments. All in all, it’s a useful addition to vCenter Server for environments using NetApp storage. The Virtual Storage Console (VSC) replaces the old NetApp Host Utilities Kit (HUK), which NetApp used to fine-tune and configure... Read More →

FlexClone Oracle Database Split Brain This article, in General,NetApp ability to clone a snapshot of an Oracle Database Lun, and then make the snapshot read/writeable, then you can clone that snapshot and so forth. If you want to delete the backing Snapshot copy, you can split the LUN clone from the backing Snapshot copy without taking the LUN offline. Any data from the Snapshot copy that the LUN clone depended on is copied to the LUN clone. SnapManager for Oracle quickly creates a writable, space-efficient clone of a database it has backed up. The clone is separate from the actual backup, so you can modify it without changing the backup source. The clone can be located on the same host as the database, or on a different host as long as it meets the requirements detailed in Cloning a database to an alternate host. SnapManager uses the FlexClone feature, which is part of Data ONTAP, to create the clone. FlexClone enables SnapManager for Oracle to use snapshots of the database to avoid... Read More →
