1. VMware vSphere Digital Quantities (vVols) aren’t supported during the an effective DRP;
2. A levels inside an effective DRP cannot be shrunk;
3. No regularity disperse between I/O groups in the event that frequency in the an effective DRP (play with FlashCopy otherwise Area Mirror/In the world Mirror as an alternative);
4. Zero split from an amount reflect to duplicate from inside the a different I/O category;
5. Real/used/free/free/tier capacity commonly advertised for each frequency – merely for each pond.

RAID and you can Marketed RAID FlashSystem 7200 systems support DRAID1, DRAID5, DRAID6, TRAID0, TRAID1 and TRAID10. For compressed drives only DRAID1, DRAID5 and DRAID6 are supported.

DRAID Strip Proportions For candidate drives, with a capacity greater than 4TB, a strip size of 128 cannot be specified for either RAID-5 or RAID-6 DRAID arrays. For these drives a strip size of 256 should be used.

Non-Disruptive Frequency Disperse (NDVM) The following Fibre Channel attached host types are supported for non-disruptively moving a volume between I/O groups (control enclosures):

Whenever moving a quantity that’s mapped so you can an atmosphere group you then need certainly to rescan disk routes with the all of the servers cluster nodes so that the the latest paths had been identified before deleting availableness on the unique I/O group.

Conceptual

Clustered Options A FlashSystem 7200 system https://kissbrides.com/indian-women/salem requires native Fibre Channel SAN or alternatively 16Gbps/32Gbps Direct Attach Fibre Channel connectivity for communication between all nodes in the local cluster. Clustering can also be accomplished with 25Gbps Ethernet, for standard topologies. For HyperSwap topologies a SCORE request will be required. Please contact your IBM representative to raise a SCORE request.

Partnerships ranging from possibilities to have Town Mirror otherwise In the world Echo replication is be studied which have each other Soluble fiber Station and you will Indigenous Ethernet relationships. Distances greater than 3 hundred metres are merely offered while using the an enthusiastic FCIP link otherwise Fibre Station ranging from resource and you will address.

Transparent Affect Tiering Transparent cloud tiering on the system is defined by configuration limitations and rules. Please see the IBM Documentation maximum limits page for details.

1. Whenever a cloud membership is created, it should continue to use a comparable security types of, in the life of the knowledge where affect account – even if the affect account object is taken away and remade with the the device, the fresh new encryption particular for that cloud membership is almost certainly not changed if you find yourself backup research regarding system can be acquired on the affect seller.
2. When performing re also-trick surgery to your a system that has an encoding allowed cloud membership, perform the commit process immediately following brand new ready yourself process. Always keep up with the previous program master key (towards the USB or in Keyserver) because this trick might still be required to help you access your own affect copy analysis when performing an effective T4 recuperation or an import.
3. Restore_uid choice really should not be put when duplicate try brought in so you’re able to another class.
4. Import off TCT information is simply served from possibilities whoever copy research was created from the v7.8.0.step one.
5. Clear cloud tiering uses Sig V2, whenever linking so you can Auction web sites nations, and won’t currently assistance places that require Sig V4.

Encoding and you will TCT There is an extremely small possibility that, on a system using both Encryption and Transparent Cloud Tiering, the system can enter a state where an encryption re-key operation is stuck in ‘prepared’ or ‘prepare_failed’ state, and a cloud account is stuck in ‘offline’ state. The user will be unable to cancel or commit the encryption rekey, because the cloud account is offline. The user will be unable to remove the cloud account because an encryption rekey is in progress. The system can only be recovered from this state using a T4 Recovery procedure. It is also possible that SAS-attached storage arrays go offline. There are two possible scenarios where this can happen:
