VMware vSAN uses a software-defined approach thatcreates shared storage for virtual machines. It virtualizes thelocal physical storage resources of ESXi hosts and turns them intopools of storage that can be divided and assigned to virtualmachines and applications according to their quality-of-servicerequirements.
Dell EMC VxRail is a hyper-converged appliance.Like VSPEX™ BLUE, the Dell EMC product that it replaces, andother hyper-converged infrastructure systems, VxRailincludes compute, storage, networking and virtualization resourcesin a single device.
StarWind VSAN Free provides a storage solutionfor several purposes such as store virtual machines. With VSANFree, you can deploy a 2-node cluster to present a highlyavailable storage solution to hypervisor such as Hyper-V or ESXifor free.
vSAN is software-defined storage thatenables organizations to pool storage capabilities andautomatically provision virtual machine storage. They candynamically scale performance and storage capacity as neededand render underlying physical storage accessible to virtualmachines through a policy-driven control pane.
A license of vSAN 6.6 is not inexpensive, comingin three varieties: Standard at $2,495 per CPU, Advanced at $3,995and Enterprise at $5,495. That's in addition to whatevervSphere licenses you need.
ESXi is the foundation for the large majority ofvirtualized environments worldwide. For standard datacenterdeployments, vSAN requires a minimum of three ESXi hosts(where each host has local storage and is contributing thisstorage to the vSAN datastore) to form a supportedvSAN cluster.
vSAN doesn't use external storage arrays— it uses server-based disk drives and flash devicesto create its own shared pool of storage. The environment ismuch simpler and more cost-effective as a result.
Nutanix operating in the user space we dohave a VM called our CVM that is the storage controller running oneach node. VSAN being embedded in the kernel doesn'tuse VM's for base functionality. To effectively manageVSAN you need to add some additional VMs, they're optionalbut do come installed with EVO:RAIL.
Configure a Cluster for vSAN Using the vSphere WebClient
- Navigate to an existing cluster in the vSphere Web Client.
- Click the Configure tab.
- Under vSAN, select General and click the Configure button.
- Select vSAN capabilities.
- Click Next.
- On the Network validation page, check the settings for vSANVMkernel adapters, and click Next.
Type "show running-config" or "show config" and pressthe "Enter" key. The IP address or addresses assigned tointerfaces on the switch are displayed in the commandline interface output.
Type "netstat -a" in the Command Promptwindow, and press "Enter." The computer displays a list of all openTCP and UDP ports. Look for any port number thatdisplays the word "LISTENING" under the "State" column. If you needto ping through a port to a specific IP usetelnet.
On Cisco Router/Switches:
- Type "terminal length 0" in privileged mode to set yourterminal to display without any breaks.
- Type "show run" or "show start" to show the applicableconfig.
- To display the config without lengthy certificate data, use"show run brief ".
The show ip interface command provides tons ofuseful information about the configuration and status of theIP protocol and its services, on all interfaces. Theshow ip interface brief command provides a quick status ofthe interfaces on the router, including their IPaddress, Layer 2 status, and Layer 3 status.
You can use the show vlan id[vlan#] command to see information about aparticular VLAN. Below you can see a sample output ofthe show vlan command. information on the particularinterface as well as the interfaces administrative and operationalmode (access or trunk mode).
