About Repositories
The Protector Repository Gen 2 is a performance and capacity optimised object store. It conforms to the Unified Backup Infrastructure storage specification. Refer to the Unified Backup Infrastructure concept for more details.
The Repository differs from other native object storage in that it supports snapshots natively utilising re-direction on write. This allows for highly efficient management of shared data blocks and space reclamation is both fast and automatic.
There are no practical limits to the size of objects or number of objects in a repository.
To achieved optimal data reduction, it retains both object level and block level check sums.
For performance optimization, the Gen 2 Repository can be setup to be split across different storage. See Repository Storage Node Wizard for more details.
- Data directory – this is the where the bulk of the data is stored. Mass storage devices with performance characteristics of fast write streaming storage is ideal.
- Metadata Directory and Checksum Directory holds the metadata and the repository structure information. These benefits from fast random access such as SDD and NVMe storage. Typically these should be around 5% of the Data Directory capacity.
Hardware and OS recommendations
This section describes the ideal additional specification information for a repository machine. For more information see the product support matrices at https://www.hitachivantara.com/en-us/products/data-protection/ops-center-protector.html#tech-specifications .
Hardware:
As usual in most scenarios more is better but a point of diminishing returns will be reached. The most beneficial upgrade is extending the available memory. The repository storage group processes themselves never use a large amount of memory, but increasing memory beyond 16GB will ensure there is plenty of head room.
More important when specifying CPU, is the generation of CPU technology. Because moving mass data is at the core of what the repository does, faster memory will have a greater impact than for a normal application so the faster memory the better.
File System:
In addition to optimising the disk layout, it is also important to use the correct block size for NTFS. NTFS volumes should be formatted using 16k block size with a repository storage group default setting. It should under no circumstances be larger than the repository DataBlockShift setting which is 16k by default. If the NTFS block size is larger, then it will force the filesystem to read the block before it performs a write.
E.g. with a 64k NTFS block size, if Ops Center Protector needs to update a single repository block of 16k, it will write out the 16k block to the file system. However the file system will need to read the 64k NTFS block, change the relevant 16k section and then write back the full 64k block. This badly degrades performance, but it may not be noticeable when the repository is initially populated since these full backups would likely be large 2MB writes across several blocks. The degradation in performance would only be noticed over time when smaller, incremental updates start occurring.
Shutdown Time:
Windows only allows a few seconds for all services to shutdown before forcibly terminating them. An Ops Center Protector repository storage group can take a significant amount of time to close especially if it is busy synchronizing many machines at the point of a system shutdown.
The time Windows allows for process shutdown can be changed via the Windows registry. The registry entry to change this is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WaitToKillServiceTimeout
The value is in milliseconds; by default it is either 12000 or 20000 depending on OS version. It is important for the repository to shutdown correctly so we highly recommend changing this value to 5 minutes (300000 milliseconds).
The knock on effect is that your server may take longer to shutdown, this setting applies to all services, so if a service is badly behaved and does not shutdown when asked, then the machine will take the full 5 minutes (plus OS cleanup time) to shutdown.
About Cloud Nodes (Amazon S3, HCP and HCP Cloud Scale)
Cloud storage nodes, Amazon S3, HCP and HCP cloud scale are used to transfer application data to cloud storage. All use the S3 protocol for communication.
Cloud storage nodes represent the storage in Amazon S3 cloud or on the HCP. When creating the node, you will define the necessary credentials to access the S3 service. These include:
- Access Key ID
- Secret Access Key
- Bucket Name
- Region (Amazon S3 only)
Additionally, you will define a Proxy node that will be the intermediary between the application and the S3 service. The proxy node can be any Windows or Linux OS nodes.
The role of the proxy node is to:
- Provide a secure system that can access the S3 service. Although the proxy node can be the same OS host as an application, it is recommended for security reason that this is an independent system to that of the application. The benefit of this is that this system can be given limited access ensuring that the application servers do not have access to the S3 credentials. This S3 node can then be used by multiple applications without the danger of compromising security or data leakage. It also means that the application servers do not need direct access to the internet.
- Provide a cache of the recovery points stored on the S3 server. This cache is only a copy of the index information and metadata, it is not the data itself and can be rebuilt from the S3 content. Having the cache however improves responsiveness of the system and decreases some of the S3 access, thereby saving cost.
- Provide an UBI compliant application interface. This allows you to use S3 storage with any of the next generation applications in the same fashion that you can use Generation 2 Repository. For a list of UBI compliant applications see XYZ. As UBI compliant storage, the S3 node can also receive data from or send data to other UBI compliant storage, such Generation 2 Repository or Generation 2 Hitachi Content Platform. This means it can be used to form a layered data retention solution.
Cloud storage node key features include:
Search friendly native format
A key feature of S3 support is to keep data stored on S3 in a native format as much as practicable. Any files less then 4GB in size, has its data stored in a single object. This means that 3rd party search, indexing and analytics tools can process the data in S3 directly. By default, files bigger than 4GB are split into 4GB segments that can easily be stitched together if required.
Delta block differencing
To reduce bandwidth and improve transfer speeds, by leveraging S3 partial transfers only the block changes within a file are sent to S3.
Virtual snapshots
A system whereby data is retained and indexed in S3 in such a way that recovery points use objects that are whole and not need rehydration but will share data that is common between other recovery points, saving storage space and providing optimal recovery speed.
Multi-factor parallelism
To further optimise data transfer speed in addition to delta block differencing, multiple objects are sent to S3 at the same time and multiple data blocks within those objects are sent separately to S3 in parallel.
Self-consistent store
Although some metadata is cached on the proxy, the data stored in S3 is self-consistent. Should a site experience complete data loss, a new instance of Protector can be spun and an S3 node can be configured to import the data.
