Stuff

  1. VMware vSphere Virtual Quantities (vVols) commonly supported within the good DRP;
  2. A quantity within the a DRP cannot be shrunk;
  3. Zero regularity flow between We/O teams when the regularity during the a good DRP (have fun with FlashCopy otherwise Location Reflect/Globally Mirror rather);
  4. No broke up of a levels echo to replicate when you look at the a different I/O classification;
  5. Real/used/free/free/level skill are belirleyici baДџlantД± not said each volume – simply for every single 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 Remove Size 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 Regularity Flow (NDVM) The following Fibre Channel attached host types are supported for non-disruptively moving a volume between I/O groups (control enclosures):

When swinging an amount which is mapped so you can an atmosphere party then you certainly have to rescan computer paths to the every server team nodes so that the the fresh paths was basically perceived before deleting availability regarding modern We/O classification.

Abstract

Clustered Possibilities 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 between solutions for City Reflect or In the world Reflect duplication can also be be taken that have both Fibre Channel and you may Indigenous Ethernet associations. Distances higher than 300 yards are only served while using the an enthusiastic FCIP link or Fiber Station between provider and you can target.

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 account is created, it will continue using an equivalent encoding sort of, about lifetime of the content in that affect membership – even when the affect membership object is removed and remade towards the the device, the latest security variety of for the affect account might not be changed when you are back-up study for this program is present on the cloud supplier.
  2. When performing re-trick functions for the a system that an encryption let affect membership, perform the going procedure shortly after brand new get ready procedure. Remember to take care of the prior system master-key (for the USB or even in Keyserver) because this key might still be needed to help you retrieve the cloud duplicate study when doing a good T4 recovery or an import.
  3. Restore_uid solution should not be put when content try imported to help you a unique class.
  4. Import of TCT data is simply offered from assistance whoever backup studies was developed at the v7.8.0.1.
  5. Transparent affect tiering uses Sig V2, whenever connecting so you’re able to Amazon regions, and won’t currently support regions that need 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:
