Nodes when you look at the a we/O class cannot be changed of the nodes having smaller memory whenever compacted amounts exists

In the event that a customer need certainly to migrate out-of 64GB to help you 32GB recollections node canisters from inside the a we/O category, they will have to eradicate all of the compressed volume copies for the reason that I/O classification. This restrict relates to seven.7.0.0 and you will new application.

Another software launch could add (RDMA) hyperlinks playing with the new standards one to help RDMA particularly NVMe more than Ethernet

  1. Would an i/O classification that have node canisters that have 64GB regarding thoughts.
  2. Carry out compressed quantities in that We/O classification.
  3. Delete one another node canisters from the program having CLI otherwise GUI.
  4. Developed brand new node canisters which have 32GB off recollections and add her or him to your arrangement regarding the new I/O group with CLI otherwise GUI.

An amount set up having numerous accessibility We/O organizations, to the a network throughout the stores layer, can’t be virtualized by a system about replication level. Which restrict prevents good HyperSwap frequency on one system being virtualized because of the various other.

Fiber Channel Canister Union Please visit the IBM System Storage Inter-operation Center (SSIC) for Fibre Channel configurations supported with node HBA hardware.

Direct connections to 2Gbps, 4Gbps otherwise 8Gbps SAN or head servers accessory to 2Gbps, 4Gbps or 8Gbps slots isn’t served.

Other set up switches that aren’t really linked to node HBA technology shall be people served cloth key once the currently placed in SSIC.

25Gbps Ethernet Canister Commitment Two optional 2-port 25Gbps Ethernet adapter is supported in each node canister for iSCSI communication with iSCSI capable Ethernet ports in hosts via Ethernet switches. These 2-port 25Gbps Ethernet adapters do not support FCoE.

The next app launch can add on (RDMA) links playing with the newest protocols one to service RDMA including NVMe over Ethernet

  1. RDMA more Converged Ethernet (RoCE)
  2. Sites Greater-urban area RDMA Protocol(iWARP)

When entry to RDMA which have a beneficial 25Gbps Ethernet adaptor will get it is possible to up coming RDMA website links only performs between RoCE slots or between iWARP ports. we.age. out-of an effective RoCE node canister vent so you’re able to an excellent RoCE vent on a host otherwise regarding an enthusiastic iWARP node canister port in order to an enthusiastic iWARP vent into an atmosphere.

Ip Connection IP partnerships are supported on any of the available ethernet ports. Using an Ethernet switch to convert a 25Gb to a 1Gb IP partnership, or a 10Gb to a 1Gb IP partnership is not supported. Therefore the IP infrastructure on both partnership sites must match. Bandwidth limiting on IP partnerships between both sites is supported.

VMware vSphere Virtual Quantities (vVols) The maximum number of Virtual Machines on a single VMware ESXi host in a FlashSystem 7200 / vVol storage configuration is limited to 680.

The utilization of VMware vSphere Virtual Volumes (vVols) into the a network that is designed getting HyperSwap is not currently supported to the FlashSystem 7200 family.

SAN Footwear function toward AIX 7.dos TL5 SAN BOOT is not supported for AIX 7.2 TL5 when connected using the NVME/FC protocol.

RDM Volumes connected to customers when you look at the VMware 7.0 Using RDM (raw device mapping) volumes attached to any guests, with the RoCE iSER protocol, results in pathing issues or inability to boot the guest.

Lenovo 430-16e/8e SAS HBA VMware 6.7 and 6.5 (Guest O/S SLES12SP4) connected via SAS Lenovo 430-16e/8e host adapters are not supported. Windows 2019 and 2016 connected via SAS Lenovo 430-16e/8e host adapters are not supported.

  • Window 2012 R2 playing with Mellanox ConnectX-4 Lx En
  • Screen 2016 using Mellanox ConnectX-cuatro Lx En

Windows NTP servers The Linux NTP client used by SAN Volume Controller may not always function correctly with Windows W32Time NTP Server

Concern Flow-control to own iSCSI/iSER Priority Flow Control for iSCSI/ iSER is supported on Emulex & Chelsio adapters (SVC supported) with all DCBX enabled switches.
