  1. VMware vSphere Digital Quantities (vVols) are not offered when you look at the an excellent DRP;
  2. An amount within the an effective DRP can not be shrunk;
  3. No frequency circulate ranging from We/O teams if the regularity when you look at the good DRP (use FlashCopy otherwise Town Echo/International Echo rather);
  4. No broke up out of a levels reflect to copy in the a different I/O category;
  5. Real/used/free/free/level strength are not claimed for each volume – only for every 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 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 Move (NDVM) The following Fibre Channel attached host types are supported for non-disruptively moving a volume between I/O groups (control enclosures):

When moving a levels that’s mapped to a host group then you certainly eros escort Athens GA need rescan disk paths toward all server people nodes to ensure the the pathways was basically sensed before removing accessibility in the brand spanking new We/O category.

Conceptual

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 systems for City Echo or All over the world Reflect replication normally be taken having both Dietary fiber Station and you may Native Ethernet associations. Distances greater than 3 hundred metres are just served when using an FCIP link or Dietary fiber Route anywhere between resource and you will 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 an affect membership is created, it must continue using an equivalent encoding style of, from the lifetime of the data because affect membership – even if the affect account target is removed and you can remade to the the system, this new encoding form of for this cloud account might not be changed if you’re support investigation regarding system is obtainable in the cloud provider.
  2. When performing lso are-trick procedures to your a network who has got an encryption allowed affect account, perform the to go operation once new prepare procedure. Remember to retain the prior program master-key (to the USB or even in Keyserver) because trick may still be required so you’re able to access the affect content analysis when doing a great T4 recuperation or a significance.
  3. Restore_uid alternative shouldn’t be utilized whenever backup are brought in to a special team.
  4. Transfer from TCT data is merely offered out-of expertise whoever content analysis was made during the v7.8.0.step one.
  5. Transparent cloud tiering spends Sig V2, when connecting to help you Auction web sites countries, and will not already service countries that need Sig V4.

Encryption and you can 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:
