How do the solutions HPE help to accelerate a backup? TADetails

What represents the solution HPE StoreOnce and for what it can be used?

HPE StoreOnce does for backup most too that does virtualization software for physical servers.

The solution HPE StoreOnce is designed to help with conditions under which:

• it is required to increase backup performance, and to install the bigger number of tape drives there is no opportunity.
• fast recovery of single files and elements is required (for example, mailboxes or virtual machines).
• there is a need to exclude use of tapes as information media.
• backup and data storage with short lifetime is required.
• the alternative or addition to technologies of instant pictures, with that not to store them on the main disk array is required.
• it is required to save the large volume of the repeating similar data.
• it is necessary to create geographically distributed structure of backup with a possibility of automatic replication of the copied data between platforms.

What advantages does HPE StoreOnce in comparison with classical backup systems have?

In comparison with the classical HPE StoreOnce systems has several advantages. So, for example, one library HPE StoreOnce emulates a set of tape drives for multithreaded record and also makes record of files on CIFS/NFS. Besides, reserve recovery begins at once after receiving a request, at the same time it is possible to perform recovery along with data writing.

Among other pluses:

• The deduplication allowing to reduce data by 20 times (a prize in the volume of 95%)
• High reliability of a disk system – principal components are duplicated, disks are protected by RAID'OM, the integrity of data is constantly checked
• Commonality, flexibility and scalability of the solution
• For the large organizations with branches - a possibility of consolidation of a backup in the center – with the subsequent replication of data in remote DPC
• Possibility of conversion of the existing tape backup for archiving

How does the technology of deduplication work?

This technology (HPE StoreOnce Deduplication) works at hardware level and processes data "on the fly". At record a system compares new blocks to those that were saved earlier. If the existing data unit was found, then it is replaced with the short link to it that allows to reduce amount of data to 20 times and to save up to 95% of disk space.

Schematically process of deduplication looks so:

On HPE StoreOnce libraries only unique data and at the exit remain, we receive the general backup of the following type:

Deduplication coefficients for standard data sets are included below

In what type it is possible to use HPE StoreOnce?

Now there are several options of use of disk libraries HPE StoreOnce. First, it is virtual tapes: virtual tape drive (for example, LTO7, LTO6 and others) and virtual library (for example, MSL 2024). Secondly - network file resources (NAS), such as CIFS and NFS. And thirdly is a new type of the disk device (HPE StoreOnce Catalyst).

Virtual tapes and network file storages are compatible to any software of backup (HPE DataProtector, NetBackup, BackupExec, etc.), and HPE StoreOnce Catalyst requires special support from backup software.

What is HPE StoreOnce Catalyst?

HPE StoreOnce Catalyst is a program interface (API) which allows to control all stages of backup, including a possibility of deduplication of data on servers with applications or backup copies before transferring them to a centralized system of backup of HPE StoreOnce. It significantly reduces the amount of transmitted data, increases performance and reduces load of channels. The StoreOnce Catalyst technology also includes new type of the target device for backup, the Data transfer protocol and the protocol of management.

HPE StoreOnce Catalyst functions both in the local area networks (LAN), and in storage area networks (SAN). The solution allows to manage on a centralized basis placement of backup copies that is convenient in the big, distributed IT environments.

What companies the solution HPE StoreOnce is expected?

The lineup of HPE StoreOnce covers and covers requirements of all segments of IT market. HPE StoreOnce will be suitable both for small office, and for large enterprises. The solution is available in two options – in the form of the virtual machine (HPE StoreOnce VSA) and in the form of the disk systems.

The Paladin Group, one of the leading players among system integrators of Russia has wide experience of implementing solutions of backup based on disk libraries HPE StoreOnce. The company works at IT market since 1994 and for 22 years successfully implements projects on design, implementation and support of IT solutions, renders services in the field of IT consulting and outsourcing. The Paladin group cooperates many years with Hewlett Packard Enterprise and has the highest partner status – HPE Platinum Partner. According to the results of activity for 2015-2016 the Paladin Group enters in TOP-10 equipment suppliers and solutions of Hewlett Packard Enterprise on all Russia.

The implementation project of a backup system of HPE StoreOnce implemented by Paladin Group on branches of HEINEKEN company in Russia became the most demonstrative and interesting. The project covered the plants in St. Petersburg, Nizhny Novgorod, Yekaterinburg, Novosibirsk, Irkutsk, Khabarovsk, Kaliningrad, Sterlitamak and also the central office in Moscow.

The solution was constructed based on the HPE StoreOnce 2700 models, 2900 and HPE VSA with the subsequent replication of data in remote DPC.

HPE StoreOnce 2700

The customer received a full-function flexible solution for carrying out backup with a possibility of further scaling of a system. In the long term the company can select a stretcher of functionality of a system: at first to increase volume, and then to increase performance, or to evenly buy controllers with disk regiments for performance improvement, and, if necessary, to increase the amount of storage.

The flexibility of disk libraries HPE StoreOnce including is defined by support of HPE Catalyst technology. Thanks to this functionality deduplication of the reserved data can directly happen on media servers, writing already deduplitsirovanny copy on HPE StoreOnce library and significantly saving the amount of data transferred to network.

HPE StoreOnce 2900

For the company with regional branches disk libraries HPE StoreOnce - the excellent solution which allows to save financial resources and more flexibly to organize management reserve copying. Purchase of libraries for each office in this case is not required, it is only enough to install on the software local media server of backup also the agent of HPE StoreOnce Catalyst. Further the backup of data will be transferred to HPE StoreOnce library at the central office.

The representative of HEINEKEN company in Russia, the head of server and telecommunication group Ivan Dunayev, notes that the company considered the implementing solution HPE StoreOnce as replacement to the tape libraries which were available at that time, a part of which became outdated, and another did not correspond to required speeds of backup and recovery. Also, according to him, the possibility of storage of backup copies on remote platforms was one of conditions of implementation of a new system.

Process of implementation took about a year, the solution was checked on two platforms in the beginning, and then after successful tests is replicated on other plants. Specialists of Paladin Group rendered full assistance at implementing solution, to its setup and start in operation. Now we have the modern solution of backup and recovery which with success proves to be on regularly tested disaster recovery and allows us to be sure of safety of data, - Ivan Dunayev tells.

Of course, in certain cases there is no need to refuse completely a tape backup. This technology is checked by time and everyone selects the equipment proceeding them the needs, however if the IT is faced by a task of optimization of a backup system, then the solution HPE StoreOnce can be rather simply integrated in the existing scheme as an intermediate link between the user systems and long-term archive. Such approach will help to reduce waiting time of a daily backup, will allow to make a partial backup of big files, without rewriting them on raid tape array completely and also to reduce time of backup and data recovery, transferring those data, access to which can be required only in the long term, to a tape.
