Metalogix StoragePoint 5.9.1 - EMC Centera Adapter Guide

Centera Adapter Configuration

This section will provide you details on how to configure a storage endpoint’s connection string to utilize the Centera Adapter. Please refer to the StoragePoint Reference Guide for information on managing Storage Endpoints.

On the Application Management page, click Storage and Backup Endpoints.

Click Create New Endpoint or click the name of an existing storage endpoint that you want to edit.

Centera Adapter Connection String Parameters

Setting

Value/Options

Name

Enter the unique name of the Storage or Backup Endpoint.

Type
EMCCentera2

See Backup Services Settings in the Reference Guide for more information on how Backup Endpoints are used.

Primary – this endpoint will be available for externalization when creating storage profiles.

Backup – this endpoint will be in the Backup Services dropdown on the profile page.

The selection is locked down when saving.

Status
EMCCentera3

Online – Storage Endpoint should be available to associate to a Storage Profile and accept BLOBs. (default)

Offline (Read Only) – A storage endpoint can be configured, but not made available for externalizing content. The BLOBs already on the endpoint are still read only.

EMCCentera4

Select the adapter for the endpoint that is being created.

EMCCentera5

IP address or host name that represents the cluster address for the Centera instance to be used.

Where examples of the cluster address could be any of the following:

Without PEA (Pool Entry Authorization) file

ADDRESS=centera.denallix.com

 

With PEA file See Appendix A for more information.

ADDRESS=128.221.200.56?us1_profile1_rwqe.pea

Required.

EMCCentera6

If supplied, the Centera adapter will calculate and supply a retention policy when saving content.  Possible settings are:

None

[DateFormat] example:

Retention=*08/31/2009;

 

[Duration][Interval] example:

Retention=5D;

[Interval] may be days (D), months (M) or years (Y).

NOTE: You can NEVER shorten the retention period once it has been established.

EMCCentera7

If the endpoint is on a WORM (Write Once, Read Many) device, Unused BLOB Cleanup will ignore this endpoint.

castor10

No – Externalized content BLOBs are not placed in folders.

Yes – Externalized content BLOBs are placed in folders (default).

If Folder Content in BLOB Store is Yes then you can select a date/time folder scheme from the dropdown.

YYYY/MM/DD/HH/MM is the default.

EMCCentera10

The Test Storage Settings button can be used at this point, or after completing the endpoint configuration, to verify that the endpoint is accessible.

castor13

No – Externalized content BLOBs are not compressed (default).

Yes – Externalized content BLOBs are compressed.

castor14

None – Encryption will not be applied to externalized BLOBs (default).

AES (128 bit) – 128 bit AES encryption will be applied to externalized BLOBs.

AES (256 bit) – 256 bit AES encryption will be applied to externalized BLOBs.

castor15

Enter a passphrase to use when generating the encryption key. Using a passphrase will help you re-create the encryption key if necessary. You can generate a random key by leaving the box blank and clicking the Generate Key button. The encryption key passphrase will be hidden.

EMCCentera15

A warning email can be sent if it encounters errors.

EMCCentera16

An online storage endpoint can be automatically taken offline if it encounters errors. If a storage endpoint is taken offline automatically, BLOBs that were intended to be written to that endpoint will go to the content database.

EMCCentera17

Default email addresses for system error and offline notification can be entered. Check the box to include the list of Default Notification Contacts specified on the General Settings page.

Example Storage Endpoint Using Centera Adapter

EMCCentera18

Click the Show Connection String checkbox to edit the connection string. Otherwise, fill in the connection fields shown for the adapter selected. Notice that the connection string parameters are name/value pairs separated by semi-colons when editing using the Show Connection String option.

EMCCentera19

NOTE: Adapter parameters are not case-sensitive.

NOTE: You should always use a passphrase when generating encryption keys. The passphrase gives you a means of re-creating keys should they become unrecoverable or corrupt. It is very important to remember or record the passphrase outside of Metalogix StoragePoint. Otherwise, encrypted content could become irretrievable in the event of a database failure.

If you choose to externalize content you should test the storage profile settings by clicking the Test Storage Settings button. A message under the button will indicate whether or not the test was successful. If the test fails the message will include the error that was the root cause of the failure.

NOTE: When testing access to an endpoint from within Central Administration, the Identity of the Application Pool hosting the Central Administration Site is the one that is being used for the test. If there are different Identities used for other Web Applications in the Farm then those identities will also need access but cannot be tested from within Central Admin itself. See BLOB Store Security and Metalogix StoragePoint Required Privileges in the Metalogix StoragePoint Reference Guide.

PEA Files

A client connection to a Centera system typically involves two pieces.

The first is the IP address or host name of the cluster itself.

The second is typically a ".pea" file which contains detailed authentication and rights information.

Here is an example: "192.168.1.10?d:\my_conn.pea"

Clients using the Centera API (this includes the StoragePoint Adapter for Centera) use a .pea file when connecting with Centera.

Each client machine (think "server in the farm") *must* have a copy of the *same* .pea file accessible for use in a consistent location. This file must also be on the machine hosting SharePoint Central Administration.

For example if the pea file used to connect is located at "D:\my_conn.pea" on one Farm machine then it must be similarly located and named on *all* Farm machines.

File system access to the pea file must be granted to the process and service identities of SharePoint. This file will be read when connecting to Centera.

(This requirement is similar to the set of identities that would be configured on a file share in the case of the built-in FileSystem adapter.)

For more information about .pea files, please see your Centera documentation.
