Figure 2. NX3600/NX3610 Controller Network Connections Figure 3. PowerVault MD Network Connections Dedicated SAN High-Availability (Recommended) It is recommended to isolate the SAN traffic from the LAN or client traffic with redundant switches for HA. All the client cables are split between the redundant client switches, and the SAN/Internal network cables are split between the redundant SAN switches. The MD controller management ports are split between the redundant client switches.
Figure 4. Dedicated SAN Solution in the High Availability Option NOTE: The MD32x0i storage array has four iSCSI data ports on each controller. Do not configure ports 2 and 3 on the same subnets as the FluidFS NAS system. They can be connected to the same switch for other clients, but must be configured on different subnets. NOTE: For more information on the details of cabling the NAS controller(s) and the MD system(s), see Cabling Overview.
Figure 5. Dedicated SAN Solution in the Non-Redundant Option NOTE: For more information on the details of cabling the NAS controller(s) and the MD system(s), see Cabling Overview. All-In-One High-Availability Option In the all-in-one high-availability option, the redundant switches are stacked and host both SAN/Internal and client network traffic. The SAN/Internal and client cables are split between the redundant switches.
Figure 6. All-in-One High-Availability Option NOTE: For more information on the details of cabling the NAS controller(s) and the MD system(s), see Cabling Overview. All-In-One Non-Redundant Option In the all-in-one non-redundant option, both the SAN/Internal and client cables are connected to the same switch. CAUTION: In this configuration, the switch is a single point of failure. NOTE: It is recommended that you separate the SAN and client subnets using virtual LANs.
Figure 7. All-in-One Non-Redundant Option NOTE: For more information on the details of cabling the NAS controller(s) and the MD system(s), see Cabling Overview. Preparing Your Management Station A management station is required to manage and configure the NAS cluster solution. The NAS cluster solution can be accessed using either the CLI or the Dell PowerVault NAS Manager. NOTE: You can either log on to the CLI or the NAS Manager.
3 Running NAS IDU The Dell NAS Initial Deployment Utility (IDU) guides you through the steps necessary to set up the network configuration and pair the controllers together. It also starts the process of pairing the system to the PowerVault MD32x0i/MD36x0i storage appliances. Before running the NAS IDU, ensure that: • • You complete the PowerVault FluidFS NAS Setup worksheet to determine your network configuration and IP address allocation for your controllers before executing this utility.
• If un-configured NAS controllers are not discovered automatically, go to step 3. 3. On the NAS Discovery screen, click Next. The MAC Controller Discovery screen is displayed. 4. Connect a monitor and keyboard to an un-configured controller. The Controller MAC Address is displayed on the monitor. 5. On the MAC Controller Discovery screen, in MAC Address, enter the MAC address that is displayed on the monitor connected to the un-configured NAS controller. 6.
21. Click Next. The iSCSI Target Discovery screen is displayed. 22. In iSCSI Discovery Address for MD Array, enter one of the iSCSI port IP addresses of the PowerVault MD array for the iSCSI target. NOTE: The NX3610 supports two MD storage arrays. In version 01.01.02.016 of the NAS IDU, if a second array is not attached to the NX3610 cluster, enter the IP address of the single storage array twice. 23. Click Next.
4 Setting Up Your MD Storage Solution Before following the instructions in this section, ensure that you have discovered and completed the initial configuration (naming, assigning iSCSI, and management port IPs) of your PowerVault MD32x0i/MD36x0i storage arrays in accordance with the topology you plan to use. This section provides the steps necessary to configure the host group and virtual disks that are required for the NAS cluster solution.
• • All four iSCSI host ports must be configured to use different individual subnets. Two of the four iSCSI host ports can be used for additional block level iSCSI access by other hosts. NOTE: The NX3600 connects to two of the four ports configured. Enabling Jumbo Frames On The MD Storage Array To enable jumbo frames on all the iSCSI ports on the MD storage array: 1. In the PowerVault MDSM, select the Hardware tab. 2. Right-click the relevant controller. 3. Select Configure > iSCSI Ports.
One Disk Group (RAID 1/10), One Hot Spare Space This option consists of one RAID 1/10 disk group with two virtual disks and a single hot spare. The single RAID 1/10 disk group is made up of eleven, 2 TB hard drives. In RAID 1/10, the total space available for virtual disks is 10 TB as the usable capacity is half of the physical disks in the disk group. The NAS cluster requires pairs of equal sized virtual disks.
two hard disks are allocated for parity. The NAS cluster requires pairs of equal sized virtual disks. Therefore, each disk group is divided into a single 8 TB virtual disk utilizing all available space in its disk group. You have 16 TB space to be allocated for the NAS cluster. High Availability A RAID 6 disk group can continue to execute read and write requests to all of its virtual disks after any two concurrent disk failures.
