virtual ip vs physical ip

div.innerHTML = html; Therefore, it is essential to consider a number of factors when choosing between the available options. resize_tooltips(); All virtual network adapters (up to 8) can be configured with the VBoxManage modifyvm command. For this purpose, NAKIVO Backup & Replication is the perfect solution. Moreover, you can set up the Screenshot Verification feature, which takes OS screenshots of test-recovered VMs. You can go to any physical server (or desktop PC for that matter) and check the status of the network connection by seeing the “media state”, if it’s enabled, it’s speed, how long it’s been up, and what it’s connectivity state is, as defined by the Windows OS on that server. }); A Virtual IP (VIP) address is an IP address that is shared by both members of a HA server pool. This is not the case with VMs as they are built upon physical hardware which is ready for use. } else if (typeof(trackcmp_url) != 'undefined' && trackcmp_url) { var fieldVal = getUrlParam(allInputs[i].dataset.name); no_error = false; if (input.type == 'text') { var form_submit = function(e) { var form = document.getElementById('_form_' + id + '_'), thank_you = form.querySelector('._form-thank-you'); addEvent(form_to_submit, 'submit', form_submit); A web-based user interface includes the following components which ensure management optimization: The latest addition to the product toolset is the Policy-Based Data Protection feature, which was introduced with NAKIVO Backup & Replication 8.1. --> This is due to constant hardware and software upgrades, frequent system failures, and breakdown of computer components and equipment, which are difficult or even impossible to repair. Understanding the Difference Between Physical and Virtual Networking. }; } tooltip.tip.className = tooltip.tip.className.replace(/ ? tooltip = create_tooltip(elem, "Enter a valid email address. Thus, security policies and procedures can be developed, documented, and implemented from a single pane of glass - that is, through the hypervisor dashboard. Currently, businesses are expected to operate on an always-on basis, meaning that even a minor interruption in business operations can lead to major repercussions. }

for (var i = 0; i < allInputs.length; i++) { If your organization runs operations which require the use of computing resources to the fullest extent, a physical server is the optimal choice. addEvent(input, 'input', function() { The virtual switch selects uplinks for virtual machines based on the source and destination IP address of each packet. With physical servers, you have to build a system of protection for each individual server, depending on its computing capabilities and resources and the sensitivity of data that it stores. tooltip.className = '_error'; Virtual IP Address. if (!no_error) { } } The product applies AES 256-bit encryption for protecting VM data, which is a data/file encryption technique used worldwide. if (elem.getAttribute('required') !== null) { After the effects of the disaster have been mitigated and the production center has been restored, you can move the workload from the DR site back to the primary site. script.onload = script.onreadystatechange = function() { var doc = document.documentElement, scrollPosition = rect.top - ((window.pageYOffset || doc.scrollTop) - (doc.clientTop || 0)); m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) if (!value.match(/^[\+_a-z0-9-'&=]+(\.[\+_a-z0-9-']+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\. var tooltip = document.createElement('div'), arrow = document.createElement('div'), inner = document.createElement('div'), new_tooltip = {}; if(el.getAttribute('required') !== null){ Figure 1: Virtual Switch Connection Between Hosts and OS Running in Virtual Machines (Graphic Thanks to VMware.com). } Learn more about High Availability (HA) in SolarWinds Orion Platform products. Thus, the product can automatically include VMs to data protection jobs if they match the policy rules. After that, you can load multiple guest OSes and server applications on top of the virtual hardware. if (typeof serialize !== 'undefined') window._old_serialize = window.serialize; } Compression shrinks the size of each data block, whereas deduplication ensures that only unique data blocks are saved. Therefore, ensuring business continuity, especially in case of disaster, should be one of the main priorities of any organization. var allInputs = form_to_submit.querySelectorAll('input, select, textarea'), tooltips = [], submitted = false;

Virtual IP addresses. That’s your first indicator that this Windows OS is running as a virtual machine instead of directly on a physical server. return results != undefined ? wrapper.appendChild(err); NAKIVO Backup & Replication provides a rich set of high-end backup, replication and diverse recovery features for virtual, physical, cloud and SaaS environments. There may or may not be any real connectivity from the virtual switch to the real physical network (and the physical switch) but in most cases, there are (as there virtual machines need network access). A virtual IP address (VIPA) is an IP address assigned to multiple domain names or servers that share an IP address based on a single network interface card (NIC). arrow.className = '_error-arrow'; Virtual LANs (VLAN) configurations may or may not be in use to further segment the network (but I’ll leave that out of this discussion). window._form_serialize = window.serialize; {n.qp?n.qp.apply(n,arguments):n.queue.push(arguments);} The product truncates (removes) the transaction logs after running VM backup or replication jobs. + serialized + '&jsonp=true'); So how do things change when a physical server is converted into a virtual machine, run on top of a hypervisor (like vSphere or Hyper-V) and connected to a virtual network? When a member of the pool goes down, the other pool member takes over the VIP address and responds to requests sent to the VIP. remove_tooltip(elem) : false; That virtual NIC is connected to a virtual switch, provided by the hypervisor that the VM is running on. var elems = form_to_submit.elements[elem.name], found = false, err = []; } form.querySelector('._form-content').style.display = 'none'; The most trusted on the planet by IT Pros. Each VirtualBox VM can use up to eight virtual network adapters, each of which in turn is referred to as a network interface controller (NIC). elem.className = elem.className + ' _has_error'; A hypervisor is then used to create and manage VMs, which have their own virtual computing resources. var rect = tooltip.elem.getBoundingClientRect(); This factor should be considered if your organization works with a large amount of data which needs to be constantly processed. !function(f,b,e,v,n,t,s) It knows that it doesn’t have Internet access because it can’t really talk to servers on the Internet. qp('init', '6673d2d57bb24553a25538442d0958d8'); };

VLAN is a custom network which is created from one or more local area networks. } }; start by creating the Layer 2 VLAN on the switch, and then assign an IP address on the VLAN Layer3 interface (SVI), just as you would on a physical router interface Moreover, NAKIVO Backup & Replication includes the LAN-free data transfer mode which includes Hot Add or Direct SAN Access features. } This way you can receive proof of VM recoverability, which is crucial for successful recovery. Each domain name will resolve to the same IP address, that of the server in question. match[2] : null; You can see that this connection is enabled but that it has “No Internet Access”. _load_script(trackcmp_url); • virtual addresses might be the same as physical addresses • might be diﬀerent, in which case virtual addresses must be mapped into physical addresses. thank_you.innerHTML = message; found = true; Private IP: Oracle RCA requires "private IP" addresses to manage the CRS, the clusterware heartbeat process and the cache fusion layer. In summary, things change when the Windows OS is moved from a physical environment to running as a virtual machine. if (!no_error && e) { return false for (var i = 0; i < tooltips.length; i++) { } no_error = false; allInputs[i].value = fieldVal; A virtual server environment allows you to evenly distribute computing resources among all running VMs, thus ensuring capacity optimization for a minimal price. n.callMethod.apply(n,arguments):n.queue.push(arguments)} This way less LAN/WAN bandwidth is consumed. }); tooltip.appendChild(arrow); var results = new RegExp(regexStr, 'i').exec(window.location.href); if (html) { return true } resize_tooltip(tooltip) : false; HSRP protocol require virtual ip address in the same subnet as physical interface ip address. If a disaster has affected or destroyed your physical server infrastructure, the damage, in most cases, is irreversible. if (elem.type != 'radio' && elem.type != 'checkbox') { elem.parentNode.appendChild(tooltip); A bare-metal server is large in size due to the powerful processing components that it contains. The product includes a variety of built-in features which allow you to significantly improve the data protection capabilities of your system. Physical servers are far more powerful and efficient than VMs, due to the fact that VMs are prone to performance issues as a result of an overflow of virtual servers in a physical machine. Hyper-V Network Virtualization provides "virtual networks" (called a VM network) to virtual machines similar to how server virtualization (hypervisor) provides "virtual machines" to the operating system. if (!tooltips[i].no_arrow) resize_tooltip(tooltips[i]); Despite that, you should still choose the server environment that would work best for you and your business, be it physical or virtual servers. Alteon determines which virtual router to use for interfaces, virtual IP addresses, and proxy IP addresses. qp('track', 'ViewContent'); Thus, just because the virtual machine’s network is “enabled” doesn’t mean that it’s “usable” if it can’t really talk to the Internet. "); } Generates ARP (Layer 2) responses for the VIP address. } if (allInputs[i].dataset.autofill === "false") { Each physical server includes memory, processor, network connection, hard drive, and an operating system (OS) for running programs and applications. This feature allows you to set up policies for protecting specific VMs which match policy rules. }; return; window._show_thank_you = function(id, message, trackcmp_url, email) { ); from a self-backup. Computer networks that provide connection-oriented service are called Virtual Circuits while those providing connection-less services are called as Datagram networks. tooltip = create_tooltip(elem, "This field is required. } Your email address will not be published. } else if (input.type == 'textarea'){ However, you should note that VM software licenses can be quite expensive as well. allInputs[i].dataset.name = window.cfields[results[1]]; This blogpost draws the comparison between physical servers and virtual machines (VMs) by highlighting the main advantages and disadvantages which each of them provide. Can be in a different subnet than the real interface IP address when used directly on an interface.. Will respond to ICMP ping if allowed by firewall rules.. Must be added individually 2) The proper configuration is having the physical interfaces and the HSRP virtual IP address in the same subnet. } script.type = 'text/javascript'; } else { elem.className = elem.className + ' _has_error'; var serialized = _form_serialize(document.getElementById('_form_5_')); You can create site recovery workflows which can be executed in the following cases: planned failover, emergency failover, failback, datacenter migration, etc. You can easily move VMs across the virtual environment and even from one physical server to another, with minimal input on your part. NAKIVO Backup & Replication has introduced a number of features which provide multiple benefits for your VMs. The product provides image-based, application-aware backup and replication for VMware, Hyper-V, and AWS EC2 environments. Self-backups are performed on a daily basis and the copied configuration data is then sent to a backup repository. For prior knowledge, the Internet which we use is actually based on Datagram network (connection-less) at the network level as all packets from a source to a destination do not follow the same path. For example, in the graphic below you can see that this Windows 2012 Server virtual machine has a “vEthernet Connection” to a “Virtual Switch”. As for the management factor, VMs are much easier to maintain than physical servers. Thus, VMs can be created and powered on in a few minutes’ time. This is the same as any server IP address, a unique address with exists in /etc/hosts. IP Alias¶. Adds extra IP addresses to an interface. ga('send', 'pageview'); } { var clientId = tracker.get('clientId'); document.getElementById('gaFieldID').value = clientId; } var validate_field = function(elem, remove) { new_tooltip.tip = tooltip; }; NAKIVO Backup & Replication ensures that the VM data sent over the WAN is encrypted before the beginning of data transfer (encryption in flight). return no_error; addEvent(input, 'blur', function() { (_above|_below) ?/g, '') + ' _below'; if (fieldVal) { ga(function(tracker) This allows host-to-guest communication but this virtual network has no access to the internet. A virtual IP address (VIP or VIPA) is an IP deliver that doesn't relate to a genuine physical system interface. } return new_tooltip; for (var i = 0; i < radios.length; i++) { validate_field(this, true); tooltips = []; } if (email && typeof visitorObject !== 'undefined') { To ensure that the DR process runs smoothly and your data can be promptly recovered if needed, consider installing third-party data protection software, such as NAKIVO Backup & Replication. Those physical NICs connect to physical switch ports. If the production site was hit by disaster, it is essential to quickly restore mission-critical data and operations so as to reduce system downtime and minimize its negative impact on business. // Insert Twitter Pixel ID and Standard Event data below var visitorObject = window[vgoAlias]; validate_field(this, true); ; n.queue=[];t=document.createElement(e);t.async=!0;t.src=v; s=document.getElementsByTagName(e)[0]; s.parentNode.insertBefore(t,s);}(window, 'script', 'https://a.quora.com/qevents.js'); remove ? Keep in mind that you can configure VLAN network configuration on each of the virtual machine network interfaces (in the hypervisor) if you are using VLAN networking. A virtual machine (VM) is a software computer used as emulation of an actual physical computer. This way you can set up an automated algorithm of any complexity which is based on your DR plan. Physical Server NIC Review We all know that physical servers have at least one (usually multiple) physical network interfaces (usually called NICs). Apart from running backup and replication jobs, NAKIVO Backup & Replication has also introduced the Site Recovery feature, which has considerably simplified the DR process. As long as the hypervisor has the virtual NIC of the VM configured to be in a “connected” state to the virtual switch, the network inside the Windows OS will appear to be “UP” (or at least the media state). In this case, you will need to copy all data stored on the server to a removable media, transport the media as well as all hardware resources that you have to a new location, and then re-install all of the system components on a new server. A virtual IP address (VIP or VIPA) is an IP address that doesn't correspond to an actual physical network interface. On the other hand, with virtualized servers, each virtual machine has a “vNIC” or virtual network interface that connects that virtual machine to a virtual switch. The physical server vs virtual server comparison should start with the definition. To expand a physical server environment, you need to buy additional hardware components, which can be very expensive, and go through a long process of installation and configuration. wrapper.className = '_form-inner'; Finally, if an Ethernet switch shows high utilization on a port, you can look at the server name on that port and determine quickly which server it is. if (! .async-hide { opacity: 0 !important} When starting a new business, you should make sure that your organization’s infrastructure can carry the workload and perform business operations without lags and interruptions. e.preventDefault(); } var time = now.getTime(); (function() { func.apply(this, arguments); At the same time, virtualization is considered a perfect option for enterprises which contain a large number of servers. NAKIVO Backup & Replication is considered one of the most affordable data protection solutions on the market. head.appendChild(script); now.setTime(expireTime); no_error = true; if (elem.options[i].selected) { Just because the media state is up, doesn’t mean that the Windows OS will be totally fooled. if (old_error) old_error.parentNode.removeChild(old_error); return no_error;
