Pure Flash Storage Provisioning

Steps to allocate SAN storage volumes from Pure Flash Storage Arrays to standalone server or cluster server.

1. Storage Provisioning to Standalone Server

Pure Flash Storage Array Non Shared Allocation Setup

Requirement Details:

Allocate storage from Pure Flash Storage array to a single server( Non Shared )

Server : SERVER001

HBA Port 0 WWPN : 1000000000000001
HBA Port 1 WWPN : 1000000000000002

Devices to be allocated : 2 Devices
1 x 10GB
1 x 20GB

Note:
Pure Array FC ports[CT0.FC0, CT0.FC1, CT1.FC0, CT1.FC1] and Server HBA ports are connected and zoned as per above diagram. Once the zones are active, the HBA WWPNs will be logged to the respective FC ports. In contrast to the EMC Symmetrix arrays, there is no Mapping required. Once created, access to volumes are enabled by CONNECTing them through HOST.

Logical Provisioning Structure:
Dell EMC VMax3/PowerMax Non Shared Allocation

1

Verify the Zoning and HBA WWPN Logins

HBA Port 0 WWPN must be logged in to CT0.FC0 and CT1.FC0 pureport list --initiator --raw --filter "initiator.wwn='1000000000000001'"

HBA Port 1 WWPN must be logged in to CT0.FC1 and CT1.FC1
pureport list --initiator --raw --filter "initiator.wwn='1000000000000002'"

2

Create HOST and add HBA WWPNs

HOST Name : SERVER001
purehost create SERVER001 --wwnlist 1000000000000001,1000000000000002

3

Create Volumes

Create 10GB and 20GB volumes
purevol create SERVER001_VOL001 --size 10G
purevol create SERVER001_VOL002 --size 20G

4

Connect the Volumes to the HOST

purevol connect SERVER001_VOL001 --host SERVER001
purevol connect SERVER001_VOL002 --host SERVER001
OR use a single command..
purevol connect SERVER001_VOL001 SERVER001_VOL002 --host SERVER001

5

Verify Connection Details

List all the volumes connected to SERVER001.
purehost list --connect SERVER001

2. Storage Provisioning to Cluster Servers

Pure Flash Storage Array Shared Allocation Setup

Requirement Details:

Allocate storage from Pure Flash Storage array to Cluster Servers( Shared )

Server : SERVER001, SERVER002

SERVER001 HBA Port 0 WWPN : 1000000000000001
SERVER001 HBA Port 1 WWPN : 1000000000000002

SERVER002 HBA Port 0 WWPN : 1000000000000003
SERVER002 HBA Port 1 WWPN : 1000000000000004

Devices to be allocated : 2 Devices
1 x 10GB
1 x 20GB

Note:
Pure Array FC ports[CT0.FC0, CT0.FC1, CT1.FC0, CT1.FC1] and both Server HBA ports are connected and zoned as per above diagram. Once the zones are active, the HBA WWPNs will be logged to the respective FC ports. In contrast to the EMC Symmetrix arrays, there is no Mapping required. Once created, access to volumes are enabled by CONNECTing them through HOSTGROUP.

Logical Provisioning Structure:
Pure Flash Storage array Shared Allocation
1

Verify the Zoning and HBA WWPN Logins

HBA Port 0 WWPNs of both servers must be logged in to CT0.FC0 and CT1.FC0 pureport list --initiator --raw --filter "initiator.wwn='1000000000000001'"
pureport list --initiator --raw --filter "initiator.wwn='1000000000000003'"

HBA Port 1 WWPNs of both servers must be logged in to CT0.FC1 and CT1.FC1
pureport list --initiator --raw --filter "initiator.wwn='1000000000000002'"
pureport list --initiator --raw --filter "initiator.wwn='1000000000000004'"

2

Create HOSTs and add HBA WWPNs

HOST Name : SERVER001
purehost create SERVER001 --wwnlist 1000000000000001,1000000000000002

HOST Name : SERVER002
purehost create SERVER002 --wwnlist 1000000000000003,1000000000000004

3

Create HOSTGROUP and add HOSTs

HOSTGROUP Name : SERVER001_002
purehgroup create SERVER001_002
purehgroup setattr SERVER001_002 --hostlist SERVER001,SERVER002
OR do it in single command..
purehgroup create SERVER001_002 --hostlist SERVER001,SERVER002

4

Create Volumes

Create 10GB and 20GB volumes
purevol create SERVER001_VOL001 --size 10G
purevol create SERVER001_VOL002 --size 20G

5

Connect the Volumes to the HOSTGROUP

purevol connect SERVER001_002_VOL001 --hgroup SERVER001_002
purevol connect SERVER001_002_VOL002 --hgroup SERVER001_002
OR use a single command..
purevol connect SERVER001_002_VOL001 SERVER001_002_VOL002 --hgroup SERVER001_002

6

Verify Connection Details

List all the volumes connected to SERVER001_002.
purehost list --connect SERVER001_002

3. Add more devices to Servers

We can further provision additional devices to the servers by just creating new volumes and connect to the Host or HostGroup.

1

Create devices and add to the HOST or HOSTGROUP

Create 1 x 30GB device and add to SERVER001
purevol create SERVER001_VOL003 --size 30GB
purevol connect SERVER001_VOL003 --host SERVER001

For shared Volumes..
Create 1 x 30GB device and add to SERVER001,SERVER002
purevol create SERVER001_002_VOL003 --size 30GB
purevol connect SERVER001_002_VOL003 --hgroup SERVER001_002

Storage provisioning may become more complex with the Local and Remote replication. Implementation of such setup demands the creation and configuration other objects like Protection Group and Pods.
