1. VMware vSphere Virtual Amounts (vVols) commonly supported into the a DRP;
2. An amount for the a great DRP can’t be shrunk;
3. No frequency circulate anywhere between I/O organizations in the event that regularity into the a beneficial DRP (use FlashCopy or Region Echo/International Echo as an alternative);
4. Zero separated regarding an amount echo to reproduce in the yet another I/O class;
5. Real/used/free/free/tier capability are not stated for each regularity – only for each and every pool.

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 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 an amount that is mapped to a breeding ground people then you certainly must rescan computer routes to your all of the servers team nodes to ensure the the brand new routes had been seen prior to deleting availableness from the brand spanking new I/O classification.

Abstract

Clustered Solutions 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 assistance to have Region Reflect or Worldwide Echo duplication is also be taken with each other Soluble fiber Channel and Local Ethernet connections. Ranges higher than 300 metres are merely supported while using the an enthusiastic FCIP connect or Fibre Channel 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. Whenever an affect membership is established, it should continue using an equivalent security method of, in the life of the data because cloud membership – even if the affect membership target is completely removed and you can remade to your the system, the security method of for that cloud membership might not be changed whenever you are support research for that program is present on the affect supplier.
2. When doing lso are-trick surgery into the a system who’s got a security enabled affect account, do the going process immediately following the fresh get ready operation. Be sure to keep up with the past program master-key (into USB or in Keyserver) because this trick can still be needed to retrieve the affect content analysis when doing a T4 recovery or an import.
3. Restore_uid alternative should not be utilized when duplicate was imported to an alternative class.
4. Import regarding TCT information is merely served off assistance whose copy research was created in the v7.8.0.step one.
5. Clear cloud tiering spends Sig V2, whenever hooking up to Amazon regions, and won’t currently assistance regions that want Sig V4.

Encoding 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 https://kissbrides.com/danish-women/aarhus/ 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:
