Suggestions to setup NetApp FAS 2220 as NAS and SAN


We are going to use VMware and also going to install NetApp FAS 2220 with the following configuration.

NetApp FAS2220 – 6U system (2U controller unit & 4U expansion shelf)
•Dual controller system (12 internal drive bays)
•12 * 2TB SATA drives – 7.2krpm hot plug disks (internal)
•4U 24 drive bay expansion shelf
•12 * 600GB SAS drives – 15krpm hot plug disks (expansion)
•8 * 1000TX data ports
•2  * Management ports

We have 12 servers, including SQL database, Exchange and File Server etc...
At the moment we are using windows server as a file server with 750GB of space in E. We have created shares and maps  the respective departmental drive to the users when they login through logon scripts. The user’s home folder is configured to connect through the user properties in AD below the Home folder section mapped to the shared drive.

I want to use the inbuilt features of the Netapp storage and also want to use it as NAS and SAN and particularly as a NAS for creating shared drives.
At the moment we don't have any Quota system on the home drive and shared drives for the admin staff teachers and students the drives keeps growing every day.

Please suggest, what would be the best way to set up this.

From the spec for FAS2220 it states Yes. And you can have NFS shares or iSCSI LUNs.

"Storage Networking Supported

iSCSI and FC for FAS2240; iSCSI for FAS2220

NFS V2/V3/V4 over UDP or TCP, PCNFSD V1/V2 for (PC) NFS client authentication, Microsoft® CIFS, HTTP 1.0, HTTP 1.1 virtual hosts"

Hence you can have iSCSI and NFS being served from the device at the same time. With regards to the environment, please perform a capacity assessment for your current workload and determine the compute resource current usage metrics [IOPS/CPU and Memory allocations/Disk space] per server.

This should help plan for licensing needs and hardware needed for the ESX(i) hosts, a simple design to get you started will include:

3 x ESXi hosts
2 x Managed switch 1Gb ports minimum

1 x vSwitch [Management VMKernel Port] - 2 Uplinks
1 x vSwitch [VM Port Group(s)] - 2/4 Uplinks
1 x vSwitch [NFS VMKernel Port] - 2 Uplinks
1 x vSwitch [iSCSI VMkernel Port] - 2 Uplinks

I used several vSWitches to give idea of scaling out but you can combine these and create less vSwitches but same number of Ports/Port Groups for your needs.

I would use RDM Physical compatibility mode though for better storage performance for my MS SQL and Exchange Server disks

We are at the configuring stage .I want to use the FAS2220 as a SAN at the moment. But at later stage i want to use the FAS2220 as a NAS for user home directories, and shared drives. Please suggest, we have 18TB of storage  on the SAN. Do i need to create a seperate aggregrate for NAS / or i have to leave some space on the FAS2220  to configure as a NAS is the future.
