4 Introduction Nuvolat has created an extensive product documentation that has all functionalities explained in detail. In the unlikely event of something being unclear or not functioning as expected you can contact the Nuvolat support team. Before contacting the Nuvolat support team we do advise you to consult your product manuals and troubleshooter. Roles, Responsibilities & Expectations Customer System Administrators at the partner Side / client side are responsible for collecting and submitting the necessary information for each support session / support ticket when its an inbound support request. System Administrators at the partner side / client side should set the correct expectation regarding resolution times with their customers / end users. System administrators / clients are requested to go through required best practices to make sure they are not over provisioning the system OR making any changes at storage / hypervisor level that are unknown to Nuvolat support team. Its important for System administrators / clients to consult Nuvolat support team before making any changes to default configuration of vrun / Hypervisor / Firewall. Incase vrun hardware appliance is procured by partner (wherein Nuvolat is only providing vrun Software and Comprehensive Hosting for vrun servers), we shall not maintain any spares at Datacenter. Partner needs to provide these spares for emergency hardware replacements. In such case, our team shall help you identify if it s a hardware issue and shall also perform replacement of hardware by coordinating with datacenter team, but RMA / procurement of new part will be managed by partner. If this involves shipment of faulty spare outside datacenter, shipment will be charged as per actual to partner. 4

5 Nuvolat Support Our support teams will manage the vrun environments 24x7 that are under contract agreement of Comprehensive Hosting Services and hosted at one of our Datacenters. Nuvolat Support team will be accountable for end to end support for vrun stack which includes managing alerts, proactive checks, diagnosis and troubleshooting of problems. Our support team shall perform periodic maintenance activity (no physical movement) of vrun stack with prior consent from partner. Comprehensive Hosting Services also includes remote hand support at our datacenter, which means should we require any assistance in replacing hardware / performing remote activities, it will be handled by our support team with datacenter support. If the vrun appliance (prefabricated) unit is procured / purchased from Nuvolat, our support team shall also manage the RMA replacement of hardware. In such case we shall also maintain spare hardware components like disk, power supply for emergency replacements. Support team shall also manage, periodic updates of Hypervisor and upgrades of vrun software with prior consent from partner and with planned downtime. Deliverables Below are the list of deliverables which is part of Comprehensive Hosting Services agreement.

7 Replacement of faulty component where vrun appliance (prefabricated is provided by Nuvolat) Replacement of faulty component where vrun is only provided as software along with Comprehensive Hosting Services and hardware is procured by partner. Licensing Procurements OS License VMWare Licenses Application License vrun License GMC License Procurement of spares where hardware is purchased from reseller other than Nuvolat Procurement of software patch, applicable software upgrades for other than vrun, NAS Share and Firewall Appliance Procurement of spares where hardware is purchased from Nuvolat Best Practices Our records show that partners / clients who have invested the necessary time in documentation and training modules often experience minimum resolution time on support sessions. This is usually because well-trained and informed partners can collect all relevant information and can help troubleshooting the environment that presents the issue. Before installing / using our products it is always advisable to read the corresponding release notes and other technical product documentation. We also advise to read through this support guide and to make sure your system administrators are aware of the Nuvolat support procedures. This documentation explains you step-by-step how to setup, manage and monitor your vrun product through the CMC and all additional tools. Version No:

Problem Management Priority Guideline Priority Level* Description** Examples Work Begins 1 CRITICAL Immediate attention required. Complete failure of critical services or hypervisor causing the web service to be completely unavailable. Any failure that causes a severe or significant impact including failures, lack of performance and/or frequent reboots to an extent that applications running on virtual machine(s) are unavailable for practical business purposes. Network or power outages or disasters. Hypervisor non-functional and not able to run one or more virtual machines. Service failures including failures that prevent servers to run on the hypervisor Emergency Maintenance. Within 15 minutes 2 MAJOR Attention required as soon as possible. Partial failure of critical services or applications. A failure that may not have an immediate effect but could lead to the unavailability of web service or server uptime. Prolonged network degradation including latency, packet loss, or off-network failures. Access problems with application, data, or other systems due to password or profile problems. Servers are running but no ability to deploy additional servers on top of the hypervisor Within 30 minutes 14

15 3 MINOR Complete or partial failure of non-critical services or applications with minimal Customer impact. Identified issues that do not impact Customer services. Routine Network Management (e.g. NAT translations, firewall rules and open ports) Remote Access troubleshooting. Remote Hands set-up and troubleshooting. Billing questions. Other unsupported Customer requests. Within 24 hours Disaster Recovery (Only with vrun DR Pack / vrun Comprehensive Hosting Services) DR Testing By default provisional compute capacity (8VPUs 16GB RAM 500GB Storage 1200 IOPS) is available and can be assigned instantly against each vrun environment for DR testing. There is no hard coded limit on number of times partner can test DR by virtualizing / performing test promote of replica VMs, although we recommend to perform it once a month. Network: Please note that, during test promote test VMs will be provisioned in separate VLAN and will not have public access, it can be accessed through GMC console to check for data integrity. Please refer to GMC product documentation on how to access replica VMs. DR Activation Process Important: Please refer Reseller Pricing Sheet on Nuvolat Partner Page for service charges of DR activation and exact deliverables. Intimating / Declaring DR: DR situation can be called by partner under different circumstances. DR SLA / SLG starts from the time of intimating DR to Nuvolat support team. Our turnaround time / response time on DR request will be 15 minutes provided the right method of communication is followed. We shall put in our best effort and initiate required logistics to bring up your production environment to live as fast as we can. 15

16 ID: Phone: (408) Please note that DR activation phone line is only meant for specific purpose, any other support request related to onsite emergency / regular support will not be entertained on this number. Please check earlier section in support guide on how to avail emergency support. Once we receive your DR request, our support team shall call you back / write you back to get formal approval on DR activation charges. Post approval, DR activation process will begin which involves: 1) Provisioning required compute capacity in shared cluster to virtualize machines. 2) Providing required number of VLANs in shared cluster network 3) Promoting replica VMs to life (replication will break as replica instance will come to life). This can be also perform by partner. 4) Restoring firewall configuration from old firewall instance to new firewall instance 5) Assigning required number of Public IPs on firewall 6) Making sure, all VMs are up and running within defined RTO (2 Hours minimum) and RPO (30 minutes minimum) 7) Post hardware replacement / disaster scenario, configuring DR VMs to replicate back to original source. 8) Post replication, bringing VMs back to live on source vrun environment. 9) Redoing / Changing network configuration and restoring firewall configuration. DNS Redirection: Post DR activation DNS redirection need to be perform by partner. Since we are not hosting DNS server managing DNS records for any partner, this need to be done by contacting your local DNS provider / vendor who manages DNS for you. Our support team shall help you to provision required public IPs for your workloads, you need to provide these IPs to your DNS provider to configure right DNS mapping.
