36 IBM i File System Used Space Free Space 1. Object deleted 2. Space released to ASP pool (only the first 4KB page zeroed out) 3. A new object is created 4. Space utilization reported by DS8000 remains the same 5. Space utilization reported by IBM i is reduced

37 IBM i File System Used Space Free Space 6. Another object is created 7. Space utilization reported by the DS8000 increases as new extent added to thin provisioned volume 8. Space utilization in ASP as reported by IBM i increases

38 IBM i Exploitation of Thin Provisioning IBM i supports thin provisioning on all IBM storage platforms The IBM i Single Level Storage architecture spreads I/O across the entire storage pool (ASP) When space is released within the IBM i storage pool the space is not released to the storage system Released space from deleted objects is not zeroes, only the first 4 KB page is zeroed Space released from delete luns only once they have been reinitialized from the storage system and the IBM i system IPLed

39 Thin Provisioning Guidelines for IBM i Thin provisioning (ESE) is not typically recommended for production volumes due to the requirement for continual monitoring of real capacity utilization Thin provisioning is a reasonable option for FlashCopy targets, especially where these are retained for a short duration and can be an excellent replacement for Track Space Efficient FlashCopy Small extents are recommended Recommendation for thin provisioned FlashCopy targets is 50% Global Mirror journal volumes can also be used to exploit thin provisioning and recommended to be sized at 50% When FlashCopy targets are thin provisioned ensure that there are adequate hardware resources to sustain the performance requirements of the application Ideally the target luns should be in the same extent pool as the source luns

40 Real-time Compression What is it? A compressed Volume is a third type of Volume Regular (fully allocated) Thin Provisioned Compressed A compressed Volume is a kind of Thin-Provisioning Only allocates and uses physical storage to store the compressed data for the Volume Supported on Storwize and XIV Compression has a latency and throughput impact

48 Best Practices 48

49 SAN Zone The basic premise of a zone is to control who can see what in a SAN. The IBM i fiber channel IOA port is considered an initiator. The DS8000 host adapter port can be either an initiator or target/endpoint. SAN zones are defined by pairing initiators and targets. Hard zoning vs. soft zoning: In a hard zone, sometimes referred to as a port zone, zone members are specified by physical port number. Hard zones are position-dependent, that is, a device is identified by the physical port to which it is connected. In a soft zone, zone members are specified logically by World Wide Port Name (WWPN). Soft zones are generally more flexible in that new devices can be attached without regard to physical port location.

50 IBM i in a SAN best practices Basic rules and recommendations: Keep IBM i in dedicated zones. Do not intermix with other platforms. Do not zone IBM i IOAs and non-ibm i host bus adapters (HBAs) to the same DS8000 host adapter (HA) port. Always try to keep the IBM i IOAs isolated. Zone one IBM i IOP-less (Smart) IOA to one DS8000 host adapter unless the workload is light. At V5R4 zone two or three IBM i IOP-based IOAs to a single DS8000 host adapter depending on the workload characteristics. Zone one IBM i initiator to one DS8000 target so it sees a single endpoint. If zones are not defined, a DS8000 host attachment can specify a port mask that controls which DS8000 I/O port an HBA is allowed to log in to. When implementing multi-path use redundant SAN switches to eliminate a single point of failure. While standards are evolving, there is no consistent or single means of documenting a SAN. In a complex environment request the network administrator to break out the IBM i components.

51 SVC and Storwize Terminology Control Enclosure Hardware until that includes chassis, node canisters, drives, power supplies and batteries Contains 2 Node Canisters Node Canister ( Node ) Hardware unit that includes fiber ports, service interfaces and SAS expansion ports 4 fiber ports per node

52 Storwize V7000 Gen1 Fiber Ports Each node canister has 4 ports Total 8 ports per V7K Note: second node canister is upside down 2 1

53 Storwize V7000 Virtualization with NPIV - best practice NPIV connection ( shown with 1 LUN owned by node 1 ) Each VIOS HBA has path to both controllers No common components ( I.e no single point of failure ) V7K will automatically fail the LUN over to node 2 in event of node 0 failure. IBM i will automatically sense the new active paths to LUN IBM i supports 1 active and 1 passive path per IBM i Host port IBM i will not log into the same controller WWPN on more than 1 port. Active path Node 1 Node SAN switch 1 SAN switch 2 Active path 2 Passive path 1 VIOS 1 VIOS 2 Passive path 2 Note: V7K ports are zoned to the Virtual Fiber wwpn

54 Storwize V7000 Virtualization with NPIV - best practice Active path 1 Active path 2 Passive path 1 Passive path Node 1 Node Zone Example SAN Switch 1: VFC1 WWPNa V7K_Node1_Port1 V7K_Node2_Port1 SAN switch 1 SAN switch 2 SAN Switch 2: VFC2 WWPNa V7K_Node1_Port3 V7K_Node2_Port3 VIOS 1 VIOS 2 Note: V7K ports are zoned to the Virtual Fiber wwpn

55 Storwize V7000 Virtualization - more information Max config for LUN = 8 active paths (I.e 8 separate ports from IBM I partition to Storwize V7000 Also have 8 passive paths for redundancy Multipath driver in IBM i uses round robin across all active paths Node 0 Node LUNS are distributed across nodes by default. For a normal host connection, 50 % of the LUNs will be using node 1 for the active paths and 50% will be using node 2 SAN switch 1 SAN switch 2 It is possible to change the active node of a LUN with the V7K. To view current node ownership from the V7K GUI, add the preferred node column in the volumes display VIOS 1 VIOS 2 The next set of ports from IBM i should be mapped to ports 2 & 4 of the V7K nodes in this example to balance usage of the V7K ports Note: V7K ports are zoned to the Virtual Fiber wwpn

56 Storwize V7000 Virtualization with NPIV What is the result of extra paths between the switch and the V7K? IBM i will not use the extra path! The driver in IBM i will only log into a svc/v7k node once per port in the IBM i partition. To provide extra paths to a LUN, connect another port in the IBM i partition to the switch Not best practice Active path 1 Active path 2 Passive path 1 Passive path 2 Unused path VIOS vfiber VIOS vfiber

57 SVC and Storwize Native Attachment via SAN switch Same connection structure as NPIV except zoned to real wwpn of adapter in IBM i instead of virtual wwpn Best practices the same as covered for NPIV Active path 1 Active path 2 Passive path 1 Passive path 2

58 Native attachment - Direct Connect Full protection One port in IBM i to 1 port in Storwize v7000 Use second port on adapter to provide path to passive node This config provides full redundancy for any component in the path to fail Ideal for small environments where 1 partition will be mapped to 1 V7K Consumes 4 ports on the V7K ( I.e 2 partitions max to a single V7K ) Active path 1 Active path 2 Passive path 1 Passive path 2

59 IBM i View of Disk View paths with SST 3, 1, 9 - Display Disk Path Status For each disk, at least 2 active and 2 passive paths should be available - more are possible by configuring more paths Note: All other Display Disk Configuration screens in SST only show 1 of the paths.

61 Storwize and SVC Zoning Summary Multiple paths between the switch and the V7K node from a single host port does provide a level of redundancy - if the path in use fails, IBM i will automatically start using the other path The downside to having multiple paths configured from the same host port is there is no way to configure IBM i to use specific target port When multiple partitions/adapters are all configured using multiple paths between the switch and V7K, the result is typically that all I/O from all partitions go through 1 port on V7K, while the other ports are left idle. Use multipath with multiple VIOS servers and assigning specific zones to balance the ports on the storage side.

62 Storwize V7000 Virtualization with NPIV - LPM Each Virtual Fibre Channel adapter has 2 WWPNs that need to be zoned and configure at the host connection for LPM Node 1 Node Zone Example SAN Switch 1: VFC1 WWPNa VFC1 WWPNb V7K_Node1_Port1 V7K _Node2_Port1 SAN switch 1 SAN switch 2 Source SAN Switch 2: VFC2 WWPNa VFC2 WWPNb V7K_Node1_Port3 V7K_Node2_Port3 VIOS 1 Target VIOS 2 VIOS 1 VIOS 2

63 Zone Configuration for Live Partition Mobility If you configure your host connection with both WWPNs, one will be active and the other offline With SVC and Storwize this will show the connection as degraded Functionally this works but if this bothers you, create 1 host connection for each VFC WWPN. One will then be online and the other offline.

75 Switch settings If you have an 8Gb Brocade Switch and connect to 8Gb host ports make sure the fillword is set to 3. If you do not you will get a large number of CRC errors on the switch and may exhibit strange SAN errors to the IBM i host adapter. portcfgfillword <port #> 3 If you have Cisco FC switch and want to use NPIV, enable NPIV on the switch to start with. Changing the setting will require a switch restart.

78 It s not really the size, but the number! Even though the external storage array has many drive, IBM i still needs multiple LUNs to perform well. Database optimizes to the number of LUNs IBM i can see. IBM i Storage Management is optimized to scale with the number of LUNs Journal can be impacted by the number of LUNs What do you mean you need that many LUNs? There s hundreds of arms backing that LUN. Don t mix capacities in the same ASP Take caution when increasing LUN size and dramatically reducing the quantity of LUNs.
