Henan Normal University is a provincial key university with a long history. The school is surrounded by the towering Taihang in the north and the Yellow River in the south. It is located in Xinxiang City, a famous city in the north of Henan Province at the intersection of Beijing-Guangzhou and Taihe Railways. Its predecessor was Zhongzhou University founded in 1923 and Plain Teachers College founded in 1951. After the founding of New China, due to the adjustment of the faculty, the school has been renamed the Second College of Henan Normal University, Henan Second Normal College, and Xinxiang Normal College. It was called Henan Normal University in 1985.
User needs:
The existing applications and general needs of Henan Normal University are as follows:
1. There are more than a dozen application systems in the old campus, and all the data are stored and backed up in the storage data center.
2. The old campus needs full SAS high-speed storage system support.
3. All data in the old campus needs to be backed up synchronously locally.
4. Set up the disaster backup center of the old campus data center in another new campus.
5. According to preliminary statistics, there are x oracle server, sql server y, and linux server z in many application systems (user data confidentiality)
6. According to preliminary statistics, there are about m important servers that need to be used for P2V backup solutions, and require rapid V2P recovery (user data confidentiality) in the event of a disaster.
7. The local data of the old campus is backed up to another local storage space. Some of the data needs to be backed up at CDP level, and the rest can be incremental backups based on the time strategy.
Dozens of application systems of Henan Normal University roughly cover the following types of servers:
1. Database server
2. OA server, etc.
3. Other application servers
4. Mail server
5. Campus card system server
6. Storage protection of teaching courseware resources
At present, all servers use hard disk storage in the machine, and there is no means to protect data. Applications such as data backup rely on a stand-alone distributed storage environment.
The topology diagram of the existing application system is as follows:
Design:
This plan is designed to maximize storage utilization and design the importance of data points, and classify the major front-end application system servers and their data. About 10TB of data enters the "main campus storage center of the old campus" in the above figure. The storage center configuration considers:
1. Based on data importance and data volume, configure a network storage system based on SAS and SATA mixed.
2. Data with high importance and data with high read-write performance requirements are stored in the SAS hard disk array, and the remaining data are stored in the SATA hard disk array, maximizing the cost performance of the data center.
3. Equipped with two 12-disk NAS + IPSAN unified network storage ReadyNAS3200, each with 8 600GB SAS hard disks.
If there is about 50TB of data for video and related applications in the university, consider storing in the "main storage of old campus video and related applications". The storage center configuration considers:
1. The amount of video and related application data is huge, and the security requirements are relatively low. The network storage system based on pure SATA is configured.
2. At present, NETGEAR's ReadyNAS unified network storage provides the world's leading full-speed enterprise-class 2TB SATA configuration, which can maximize the guarantee of large-scale high-speed storage of video and application data.
3. Configure two 12-bay NAS + IPSAN unified network storage ReadyNAS3200, each with 12 2TB SATAII full-speed enterprise hard drives.
In addition, considering the security of the main storage data, all important data needs to be backed up locally. It is recommended to design the "Old Campus Main Storage Backup Center" to backup the 10TB data of the main storage center to the near line.
1. Based on the security and growth of the main storage data, it is recommended to configure the SATA based cost-effective network storage in the main storage backup center.
2. Considering the multiple copies of the near-line backup of the main storage data, it is recommended to configure twice the capacity of the main storage center in the main storage backup center.
3. Configure two 12-bay NAS + IPSAN unified network storage ReadyNAS3200, each with 12 1TB SATAII full-speed enterprise hard drives.
Considering the security of important data in the old campus, in addition to local near-line backup, it is recommended to recommend a remote disaster recovery center in the new campus to ensure that when an unpredictable disaster occurs in the main storage data center of the old campus, you can use the new The backup data of the campus disaster recovery center restores all important business and data of the school in time. The construction of the disaster recovery center is considered as follows:
1. Based on the consideration of the amount of main storage backup data in the old campus, it is recommended that the disaster recovery center established in the new campus should have twice the capacity and the original data volume.
2. Considering the large amount of data, it is recommended that the data backup line from the old campus to the new campus use Gigabit fiber, and combine the incremental backup strategy of files and data blocks to ensure the success rate of data disaster recovery.
3. Configure two 12-bay NAS + IPSAN unified network storage ReadyNAS3200, each with 12 2TB SATAII full-speed enterprise hard drives.
In the construction of data protection solutions for each application system server, it is recommended to configure the Symantec backup and recovery solution BcakupEXEC, which works closely with NETGEAR. In the campus data center backup solution, consider the oracel database server and sql database server and files are opened to perform backup The success rate is mainly configured with the following components:
1. Windows system main backup server
2. Oracle Database Backup Agent
3. SQL Database Backup Agent
4. Open the file backup function option
Under the cooperation of various SymantecBE backup functions and RALUSforReadyNAS, the server system data backup process described in the following figure can be realized:
In addition, considering the recovery of some important servers in the event of a disaster, it is recommended to configure NETGEAR's world-leading P2V and V2P backup and recovery solutions. This solution combined with VMwareESX (i) can implement the following global leading solutions for important servers:
1. Bare metal recovery solution
The traditional backup mechanism is mostly based on data protection, and ignores the protection of the system and production services. When a system disaster occurs, you must prepare all system configuration information and spend time reinstalling and setting up the system before you can After data recovery, the final production is possible to run normally.
In fact, there are various types of data that we need to protect:
Our innovative bare metal recovery solution is based on the premise of rapid recovery of business production, complete protection of the system and business data. In the event of a system disaster, according to the original iSCSI remote boot technology, the system and business can be run directly on the ReadyAS storage device, and then You can restore the system and business data backed up by the ReadyNAS device to the original business host while the business is running.
In addition, if the original production host device cannot be turned on at all, the latest P2V (physical machine to virtual machine conversion) can still be used to directly convert the system and business data backed up in the ReadyNAS storage device to the overall data that the virtual machine platform can start. Ensure that the system starts the system and runs the business on the virtual machine. In the three cases shown in the following figure, the system and business rapid recovery plan.
Advantages of NETGEAR bare metal recovery solution:
Provide system, application and data protection in one
Provide a host-based data replication solution
Use file data integrity and consistent transmission
Make a copy backup of the volume
Based on SAN architecture, providing LAN-free backup mode

2. N + 1 disaster recovery backup solution
In today ’s network environment, there are many types of servers in the metropolis, providing different types of services. The business of these servers needs to implement data protection measures, and unexpected situations can never be predicted. It may be that the hard disk is damaged, and It may be that the hardware motherboard is damaged, it may be a human operation error or virus damage, etc., or one server may fail, or multiple servers may fail at the same time. In response to these unforeseen unexpected situations, is there the simplest disaster recovery solution?
NETGEAR launched the latest N + 1 disaster recovery backup solution. No matter which of the above-mentioned accidents occurs, no matter how many devices fail at the same time, the backup can be backed up from the ReadyNAS storage device through a disaster recovery server deployed in advance. The data is started to ensure the normal operation of the business in the shortest time.
Advantages of NETGEARN + 1 disaster recovery backup solution:
Server host system and business data CDP backup to ReadyNAS storage device
Differential backup based on data blocks to ensure the consistency of data changes quickly
VMWAREESX (I) platform deployed on disaster recovery server
In the event of a disaster, the data backed up on the ReadyNAS can be quickly converted to disaster recovery servers through P2V. The available data system and business data can be recovered online through V2P
3. Virtualized remote disaster recovery solution
For the disaster recovery of the business system of the campus data network, the local N + 1 is sometimes not safe enough. Some business system paralysis caused by force majeure factors may cause the entire local computer room to be inoperable. It is necessary to build a disaster recovery in a remote location The center takes over critical business data and systems at critical times. Usually this demand will be limited by two aspects: large data volume and narrow network bandwidth.
NETGEAR's remote disaster recovery solution uses innovative CDP, P2V, block differential backup, high data compression, and UDP optimization processing technologies to ensure fast and safe remote disaster recovery, and business takeover can be achieved through off-site virtual machines.
Advantages of NETGEAR virtualized remote disaster recovery solution:
Using local CDP and online P2V (real machine to virtual machine conversion) technology, the virtualized disaster recovery solution replicates the local server's operating environment (system, applications, data, system configuration, etc.) to the disaster recovery center.
Based on disk block differential backup technology, ensure that the amount of data transferred is as small as possible
All business takeovers of the remote disaster recovery center are implemented using virtual machines
The highest compression ratio can be transmitted in WAN up to 4: 1, and optimized through UDP
4. CDP continuous data protection scheme
CDP (ContinuousDataProtection) is a continuous data protection scheme, which can effectively protect data when any data changes. CDP technology will be a data protection technology that has only one data mirroring, backup, or copy in the past. It has evolved to the latest and can have many data. Data protection technology for mirroring, backup or copy. The technical solution can protect data copies at different historical time points, and can restore data at any time point in the shortest time when the original data is damaged or lost.
NETGEARCDP continuous data protection solution not only covers all kinds of disaster protection (including man-made failures, viruses, software failures, hardware failures and other disasters), but also can provide comprehensive data protection for different host servers, databases, and storage environments. The scheme can minimize RPO (Recovery Point Objective) and RTO (Recovery Time Objective).
