  1. VMware vSphere Digital Amounts (vVols) aren’t served within the a DRP;
  2. A quantity during the an excellent DRP cannot be shrunk;
  3. No volume circulate between We/O groups if volume into the a good DRP (have fun with FlashCopy otherwise Urban area Mirror/International Mirror rather);
  4. Zero separated off a quantity reflect to replicate during the a different sort of I/O class;
  5. Real/used/free/free/tier potential commonly advertised for each and every volume – just for each pond.

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

DRAID Remove Dimensions 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-Turbulent Regularity Move (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 which is mapped so you can an atmosphere group then you certainly need rescan drive routes on all of the servers people nodes so that the the brand new pathways was in fact perceived in advance of deleting availableness regarding fresh We/O classification.

Conceptual

Clustered Expertise A FlashSystem 7200 system 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 systems to possess City Reflect or International Reflect replication is be used with one another Soluble fiber Station and you can Native Ethernet relationships. Distances greater than three hundred yards are merely offered while using the an enthusiastic FCIP hook up or Dietary fiber Route anywhere between resource and you will address.

Clear Cloud 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. When an affect membership is made, it should continue using the same encryption method of, regarding the life of the data in this cloud membership – even when the cloud account target is taken away and you may remade into the device, the fresh new security type of for the cloud membership may possibly not be changed if you are back-up data regarding system is obtainable on the affect merchant.
  2. When doing re-trick operations into the a network who’s an encryption allowed cloud membership, carry out the commit procedure just after this new get ready process. Ensure that you maintain the prior system master key (towards the USB or in Keyserver) as this key might still be required in order to retrieve your affect duplicate investigation when doing a good T4 recuperation or a significance.
  3. Restore_uid choice should not be used whenever click this over here now backup try imported to help you a unique team.
  4. Import regarding TCT info is simply served out-of systems whoever content study was created at v7.8.0.1.
  5. Transparent cloud tiering spends Sig V2, when hooking up to Auction web sites places, and does not currently service countries that require Sig V4.

Encryption and you may 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:
