5 1.1 Lab Preparation Considerations and Caveats It is in your best interests to ensure the demo environment you will be demonstrating is clean & tidy before you begin. For this reason we would recommend, where possible, you log in to your demo at least 15 minutes prior to delivery and check the following; 1. Familiarize yourself with the environment during this time and check any specific features you are expecting to demo. 2. Most importantly, be crystal clear with yourself on what it is you plan to show. A full demo of every feature described below (with questions) can take several hours. If you only have a short time slot be sure to focus on the key points that address the customer s pain points and will drive value home to them. 3. Ensure that you have scheduled the demo for sufficient time so as not to have the demo end before you are finished with the customer. Any other guidance on how the user should prepare for the lab can be added here. If there are limitation or something the user should be aware of call out also. 5 Dell Demo Center Dell Inc., 2016

46 3.2 Data Protection Introduction In this demo you will be performing the following tasks: - Create a Manual replay - Delete Files to Simulate Recovery - Local Recovery - Delete View Volume - Create Replication - Viewing Replications Gotchas: - Some of the older documentation refers to Unlimited Snapshots. Although the snapshot limit is so high as to be effectively limitless for most customers be aware that there is actually a soft limit today and the terminology used should be practically limitless. - Be aware of the worst-case scenario for snapshots: that a tiny change to data (4k) could take 2MB on the SAN due to the page allocation. However explain to the customer that for applications that have this kind of write profile a 512K page could be used and that the snapshot overhead will typically reside on T3 disks. - Snapshots are crash-consistent unless an application-aware technology is being used to take them. Explain the benefits of Replay Manager. - Be sure to point out that SAN-based snapshots are not intended to replace traditional backups and should not be considered an E2E DR solution on their own. For single-system/single-site environments a traditional backup is still recommend for true DR coverage. 46 Dell Demo Center Dell Inc., 2016

69 3.4 Hands-On Hyper-V stretched cluster and Live Volume Introduction The Dell Compellent storage infrastructure is based on a typical DR / LV organization with two Storage Centers 6.5, each connected a node configured in a Microsoft Hyper-V cluster based on two Windows Server 2012 R2 DC 64-bit Operating Systems. As the physical characteristics of the different components may change, we will not focus on details but just highlight the overall architectural layout: As mentioned, we have an already configured Hyper-V stretch cluster, with a few configured volumes and virtual machines that we will use for our disaster recovery and failback testing procedures: 69 Dell Demo Center Dell Inc., 2016

Depending on cluster status and events, it may be necessary to manually bring these disks online.

70 You can verify the status of the overall cluster or of any single node of the cluster using the Failover Cluster Manager. Verify that the quorum and cluster disks are on line. Depending on cluster status and events, it may be necessary to manually bring these disks online. If the disks does not come online, it may be necessary to access Disk Management and rescan the disks on each node to make sure they are visible on each node. Once all the cluster disks are online, then verify the health of the cluster resources. 70 Dell Demo Center Dell Inc., 2016

71 In this example, there are four guest VMs to verify. If necessary, manually start the guest VMs and then verify that they are properly functioning. Clearly the number and size of configured CSV and VMs, and consequently the number of the already configured Live Volumes, can vary and can be adjusted depending on your needs; in the following sections of this paper we will also address some basic configuration topics in order to help you in modifying the configuration to better meet your needs, but please consider that this document is not intended to be a summary of Hyper-V configuration procedures and best practices, just a survival guide. In this example, the environment has been set up as follows: The primary and secondary locations are well connected with adequate data bandwidth and low latency between them to allow for data replication. Both locations are remotely accessible to administrators. This is important to ensure a timely response to a DR event. A Dell Compellent Storage Center is configured at each location, each with sufficient IO and volume (space) capacity to support the Hyper-V stretch cluster s resources. Here are the major details of the currently configured server and storage infrastructure. Resource Name IP Address (Mgmt) IP Address (idrac) Remarks Server DT-POC-PRI W12 Server DT-POC-DR W12 Storage SC /97 Management IP Storage SC /197 Management IP EM DC POC-Mgmt-Srvr VM 1 VM Gen1 W2008R2 VM VM Gen1 W2008R2 VM VM Gen1 W2008R2 VM VM Gen2 W2012R2 VM name suffix shows the CSV # where the VM has been created and configured (e.g. HyperV- CSV1, HyperV-CSV2, ). CSVs sizes are: 1 TB for CSV1, 2 TB for CSV2, 2.5 TB for CSV3 71 Dell Demo Center Dell Inc., 2016

72 An Enterprise Manager Data Collector Server is installed and configured as an external location. Usually in a real world configuration a DC will be configured in Site A, and also at the recovery location, Site B. For example they could be installed on virtual servers that are not part of the stretch cluster. The remote Data Collector server s role is to maintain a copy of the volume recovery point information from the primary Data Collector server at Site A. This information on the remote Data Collector server must be accessible at the recovery site in order to activate disaster recovery. At least two instances of the Enterprise Manager Client are installed: - One instance is installed at the primary location on a virtual server that is not part of the stretch cluster - A second instance is installed at the remote location on a virtual server that is not part of the stretch cluster. Installing an instance of the Enterprise Manager client on the same VM as the Data Collector is supported and recommended. Note: The above list covers common design considerations for a stretch cluster environment but is not meant to be all-inclusive. 72 Dell Demo Center Dell Inc., 2016

73 3.5 Cluster Shared Volumes (CSV) and VMs creation In order to create and add to the Hyper-V cluster a new CSV, the very first step is just to create a new LV assigning, for example, the primary volume to the primary node (DT-POC-PRI-W12) and the secondary copy to the other node in the cluster (DT-POC-DR-W12). Note Please do not forget to use the Advanced Mapping panel to assign the same LUN ID to the two LUNs that the Live Volume wizard will create on the two storage centers (primary and secondary) and finally map to the two Hyper-V clustered servers. Note: Also use Edit Live Volume Settings to adjust server and LUN configuration on the DR site. This is fundamental for a proper failback procedure. 73 Dell Demo Center Dell Inc., 2016

74 Once the LV has been configured, you can perform a quick Live Volume swap operation between primary and secondary storage, and vice-versa, to test the new configuration. You can also modify LV settings, e.g. replication type. Now, from the first node of the cluster or, anyway, from the node hosting the primary copy of Live Volume, run the following GUI / command that will run you directly in the Disk Management menu: Server Manager > Tools > Computer Management > Disk Management 74 Dell Demo Center Dell Inc., 2016

As in any traditional Windows system, we will need to put the new disk (volume) online, initialize it and finally format it as MBR or GPT depending on its

75 As in any traditional Windows system, we will need to put the new disk (volume) online, initialize it and finally format it as MBR or GPT depending on its size or your needs. Do not assign any drive letter now. We can now run Failover Cluster Manager: 75 Dell Demo Center Dell Inc., 2016

76 Select Add Disk in the Disk panel and add the newly created Live Volume to the cluster. Once added the new disk, again from Failover Cluster Manager, select the new disk, right click on it and select Add to Cluster Shared Volumes. From now on the new CSV should be properly configured into the cluster and this is a great time to test its failover functionalities Hyper-V cluster side, moving it from one node to the other and checking its status independently from the LV configuration. 76 Dell Demo Center Dell Inc., 2016

Note: Basically from now on you should be able to see the new CSV online after any swap between the two nodes of the cluster and completely independently from the LV status.

77 Note: Basically from now on you should be able to see the new CSV online after any swap between the two nodes of the cluster and completely independently from the LV status. For example the new CSV could be in UP status on the DR node while the primary LV is on the storage connected to the PRI node, and vice-versa Note: Originally Introduced in Windows Server 2008 R2 Failover Clustering, CSVs allow all nodes in a cluster to simultaneously have read-write access to the same LUN that is formatted as an NTFS or ReFS (2012 R2 only) volume. Using CSVs, clustered roles can fail over quickly from one node to another node without requiring a change in drive ownership, or dismounting and remounting a volume. In Windows Server 2008 R2, only Hyper-V workloads were supported on CSVs. Windows Server 2012 expanded CSV functionality, allowing CSVs to be utilized as file shares with the Scale- Out File Server role. Scale-out file shares can host application data, such as Microsoft SQL Server and Hyper-V guests We can now create a new VM on this CSV. Just select Roles in Failover Cluster Manager and then New Virtual Machines : 77 Dell Demo Center Dell Inc., 2016

78 The wizard will ask for the target node: The wizard will also ask you to assign the target folder, and you will select the standard CSV directory in C:\ClusterStorage\Volume(n), where n is the assigned volume number: You ll need to complete a few more steps, assigning for example the generation of the VM, its configured memo size, and finally the desired operating system. 78 Dell Demo Center Dell Inc., 2016

79 3.6 Preliminary testing You can start or complete now some preliminary tests on this new cluster configuration and Live Volume infrastructure. You can use now the standard LV documentation and procedures to double check that, against any LV swap between primary and secondary node and vice-versa both the CSV and all the configured VMs stay respectively in UP and RUNNING status: 79 Dell Demo Center Dell Inc., 2016

80 Basically the following two snapshots show how, after LV migration, both the CSVs and the configured VMs are still on-line and running. 80 Dell Demo Center Dell Inc., 2016

seamlessly move from one node to the other of the Hyper-V

81 A further test could be that, after swapping Live Volumes, both the VMs and the CSVs preserve their capabilities to seamlessly move from one node to the other of the Hyper-V cluster: 81 Dell Demo Center Dell Inc., 2016

3.7 Disaster Recovery Test and Failover Procedures Disk failure Probably the best way to simulate a disaster is simply to delete the primary volume in a Live Volume relationship.

83 3.7 Disaster Recovery Test and Failover Procedures Disk failure Probably the best way to simulate a disaster is simply to delete the primary volume in a Live Volume relationship. Just delete the volume from its primary node and even skip the recycle bin: the primary volume is completely destroyed. From now on, all the applications insisting on this CSV, along with the CSV itself, are completely unavailable, and this is basically T 0 for our RTO period. Once the volume has been deleted, it will disappear from the Live Volumes tab and the corresponding Restore Points row will show a degraded status; right click on the relevant restore point and select Activate Disaster Recovery : A pop-up menu will allow you to select different restore options and, depending on your needs, you can select the desired PITC or, as in this example, the active replay, along with other mapping options: 83 Dell Demo Center Dell Inc., 2016

84 Do not forget to use the Advanced Mapping option to verify that the DR Volume that will be created will keep the original LUN ID. 2 You can check the status and completion of the DR procedure through the Recovery Progress tab. If you will, you can RDP to the DR site; Note For example, and for sake of simplicity, CSV #1 uses LUN ID = 10 on both nodes, CSV # 2 uses LUN ID = 20, and so on and so forth 84 Dell Demo Center Dell Inc., 2016

85 And again perform a volume rescan through the GUI: Server Manager > Tools > Computer Management > Disk Management. Once completed open Failover Cluster Manager and move the offline CSV to the DR node; it will become immediately available and now you can restart the impacted VM or VMs: 85 Dell Demo Center Dell Inc., 2016

86 This completes your downtime period and basically measures your real RTO. Once the cluster has been recovered, or the primary node is back again and up and running, it s high time to reactivate the LV relationship. In this example we have assumed a major disaster, with a Live Volume completely destroyed, and this basically means that the rollback procedure will have to replicate back all data from the DR site to the primary site. In a second example we will consider the case of a whole Storage Center failure and see that when the system is back into production, the alignment time simply depends on the amount of data written in the remote site after all DR copies have been brought back into production. In any case this procedure, where you basically select the desired recovery point and Restore/Restart DR Volumes, is not service affecting and the re-alignment of the primary and secondary (formerly primary) copies runs in the background. Basically we are coming back to a fully protected Live Volume scenario. 86 Dell Demo Center Dell Inc., 2016

As mentioned before you can monitor the progress of this recovery procedure from both the Recovery

Note If you simply delete the primary or secondary volume leaving these in the recycle bin, here

Secondary volume deleted: LV Status is: DOWN Cluster status is: Active LV status after volume

87 As mentioned before you can monitor the progress of this recovery procedure from both the Recovery Progress tab of from the main Live Volume panel. Note If you simply delete the primary or secondary volume leaving these in the recycle bin, here is the expected behavior of the whole system. Secondary volume deleted: LV Status is: DOWN Cluster status is: Active LV status after volume recovery from recycle bin: UP Primary volume deleted: LV Status is: DOWN Cluster status is: DOWN LV status after volume recovery from recycle bin: UP 87 Dell Demo Center Dell Inc., 2016

this status will be to move the resource to the other node of the cluster, bringing it online, using Failover Cluster Manager and benefitting of the proxy link between the

88 Another way to simulate a partial disaster is to remove the mapping to the host from the primary volume in a Live Volume relationship. After removing mapping, the corresponding resources (CSV, VMs, ) will go down: The Live Volume Status tab will show no problem and the best and quickest way to recover from this status will be to move the resource to the other node of the cluster, bringing it online, using Failover Cluster Manager and benefitting of the proxy link between the two storage subsystems. Another way to solve this failure status could be to swap the Live Volume relationship promoting its secondary to primary role: 88 Dell Demo Center Dell Inc., 2016

Once completed this swap you ll have to simply move the cluster resource from its former primary node to the secondary node (now primary in the Live Volume relationship):

Removing or losing mapping from a Live Volume perspective from the secondary system does not create any disruption at Hyper-V cluster level.

89 Once completed this swap you ll have to simply move the cluster resource from its former primary node to the secondary node (now primary in the Live Volume relationship): When possible you ll recreate the broken mapping to the host and, if desired, recreate the original Live Volume relationship. Removing or losing mapping from a Live Volume perspective from the secondary system does not create any disruption at Hyper-V cluster level. For example, should you delete the secondary Live Volume you ll have: Please consider that, as now the Live Volume relationship is missing, the broken Live Volume will be shown in the replication tab: 89 Dell Demo Center Dell Inc., 2016

Run Restore/Restart DR Volumes and the system will show this panel: Note Do not forget, once completed the restore activity, to add the proper mapping to the secondary Live Volume as it will be

90 Run Restore/Restart DR Volumes and the system will show this panel: Note Do not forget, once completed the restore activity, to add the proper mapping to the secondary Live Volume as it will be created without any mapping: just map it to the secondary host in the Hyper-V cluster and assign the relevant LUN ID. The following tables summarize the different cluster and Live Volume statuses, their relationship and the related stretch cluster service level with different Live Volume mapping status and in the case of volume failure. Basically these tables assume Host A as connected to Storage Center A and Host B connected to Storage Center B; the (Primary) and (Secondary) note just describe a hypothetical Live Volume configuration.

92 3.8 Storage Center failure scenarios In our testing scenarios we have checked the following possible events: Cluster resources Primary SC Secondary SC Active on Host A Complete SC failure Complete SC failure Active on Host B Complete SC failure Complete SC failure 92 Dell Demo Center Dell Inc., 2016

93 Complete failure of Primary SC (Resources on Host A) After a complete failure of the primary SC, all Live Volumes are in DOWN status and the cluster services are inoperative; from now on, all the applications insisting on this CSV, along with the CSV itself, are completely unavailable, and this is basically T 0 for our RTO period. To restart services, go to Restore Points tab in Replication / Live Volume panel of Enterprise Manager, select the desired Live Volume and, starting from quorum volume, progressively activate the disaster recovery counterparts: In the Recovery Progress tab, you ll see the progress of these events, and when their status is Finished for all Live Volumes, you have completed your disaster recovery activities (T 1 for our RTO period): 93 Dell Demo Center Dell Inc., 2016

94 Once the primary storage center is back again and ready to rejoin the production environment, just run for each Live Volume, again starting from the quorum volume, the Restore / Restart DR Volumes procedure: Again, when completed, in the Recovery Progress tab you ll see: 94 Dell Demo Center Dell Inc., 2016

Note: Please consider that in this case the fail back procedure will be quicker than in the case of complete loss or destruction of the primary volume because the system has just to copy back only

95 Note: Please consider that in this case the fail back procedure will be quicker than in the case of complete loss or destruction of the primary volume because the system has just to copy back only the data modified since the disaster, and not the complete volume. Note: Also, do not forget to check that after completing the failback procedure, all Live Volume LUNs still keep the originally assigned LUN Id. On each storage center Complete failure of Secondary SC (Resources on Host A) After the crash of the secondary SC, all Live Volumes status is DOWN but applications are unaffected and you can move VMs between the two nodes, even if you cannot move CSVs: Right after secondary SC rejoins the Live Volume configuration, Enterprise Manager automatically reconfigures all Live Volumes in a fully available status, and the Hyper-V cluster reacquires all swap functionalities: 95 Dell Demo Center Dell Inc., 2016

96 96 Dell Demo Center Dell Inc., 2016

97 Complete failure of Primary SC (Resources on Host B) This case is much similar to case #1. After a complete failure of the primary SC, all Live Volumes are in DOWN status and disappear from the Live Volume tab. Cluster services are inoperative, and from now on all the applications insisting on this CSV, along with the CSV itself, are completely unavailable, and this is basically T 0 for our RTO period. To restart services, go to Restore Points tab in Replication / Live Volume panel of Enterprise Manager, select the desired Live Volume and, starting from quorum volume, progressively activate the disaster recovery counterparts: In the Recovery Progress tab, you ll see the progress of these events, and when their status is Finished for all Live Volumes, you have completed your disaster recovery activities (T1 for our RTO period): 97 Dell Demo Center Dell Inc., 2016
