IsilonSD cluster deployment requirements using IsilonSD Management Server 1.0.0
These prerequisites apply to the production version of EMC IsilonSD Edge with IsilonSD Managment Server 1.0.0. Before you deploy IsilonSD Management Server and an IsilonSD Edge cluster, verify that the requirements listed here are satisfied.
|VMware vCenter||Version 5.5 Update 2|
Access VMware vCenter through the VMware vSphere Web Client (browser-based client).
Mozilla Firefox version 39.0 and later and Google Chrome version 42.0 and later.
Note: VMware vSphere Web Client Integration Plug-in does not work if you access Chrome version 42.0 and later and Mozilla Firefox version 39.0 and later. Refer to the following knowledge base articles to address the issue:
|We recommend the latest versions of these web browsers.|
Minimum unused RAM: 6 GB per node
|vCPU||Minimum vCPUs: 2 per node|
|Drive type||SATA, SAS, SSD|
IsilonSD Edge is supported on systems that meet the minimum deployment requirements and are built with Virtual SAN-certified components. For more information, see Identify IsilonSD Edge compatible systems.
We highly recommend the following hardware:
Either 6 or 12 defined data disks.
Physical disks, typically mirrored SSDs, are used for creating boot disks.
Total disks (data disks, journal disks, and boot disks put together)
In some cases, either the ESXi host or vCenter is unable to recognize the SSDs and the SSDs are incorrectly displayed as HDDs. To fix this issue, connect to the ESXi host or vCenter through the SSH client and run the following commands:
esxcli storage nmp satp rule add --satp=VMW_SATP_LOCAL --device <disk-naa> --
esxcli storage core claiming unclaim --type=device --device <disk-naa>
esxcli storage core claimrule load
esxcli storage core claimrule run
esxcli storage core claiming reclaim -d <disk-naa>
esxcli storage core device list -d <disk-naa> |grep SSD
Where disk-naa is the Network Address Authority identifier for the disk. For example, you can specify naa.6b8ca3a0f14b6f001c26242406e51fcf for disk-naa. See http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2013188 for more information.

Other networking recommendations
A few other networking requirements follow:
- Nodes must be on the same Ethernet network.
- The Ethernet network must allow broadcasts to be propagated between the nodes.
- IsilonSD Management Server supports the vSPC (Virtual Serial Port Concentrator) service to provide serial console access to nodes. The vSPC service listens on port 8080. Make sure that port 8080 is open and available on the ESXi host for the vSPC connections. Sometimes ESXi firewall settings can prevent transmissions. To avoid this issue, we recommend that you add a Firewall Rule Set for the serial port network connections before you connect network-backed virtual serial ports. Connect to the serial port output through a network with the virtual serial port concentrator option enabled to allow only outgoing communication from the host.
