Get 1z0-499 Dumps : Verified Oracle ZFS Storage Appliance 2017 Implementation Essentials

C: The remote replication is Asynchronous. Because replication takes snapshots and then sends them, data is necessarily committed to stable storage before replication even begins sending it. Continuous replication effectively sends continuous streams of filesystem changes, but it's still asynchronous with respect to NAS and SAN clients.

High performance is an important consideration when choosing a solution to protect an Oracle Exadata Database Machine. The following technologies make it possible for the Oracle ZFS Storage Appliance to achieve these backup and restore rates:

• (B) Hybrid Storage Pools – Oracle introduces an innovative Hybrid Storage Pool (HSP) architecture that utilizes dynamic storage tiers across memory, flash, and disk. The effective use of direct random access memory (DRAM) and enterprise-class software specifically engineered for multilevel storage is a key component that facilitates the superior performance of the Oracle

• ZFS Storage Appliance.
• (D) RMAN Integration – Oracle Recovery Manager (RMAN) is a highly parallelized application that resides within the Oracle Database and optimizes backup and recovery operations. The Oracle ZFS Storage Appliance is designed to integrate with RMAN by utilizing up to 2000 concurrent threads that will distribute I/O across many channels spread across multiple controllers. This improves performance dramatically with sequential large-block streaming I/O workloads that are typical for most backup and restore situations.
• (E) InfiniBand Support – The Oracle ZFS Storage Appliance can be configured with a highly redundant and scalable InfiniBand architecture. This allows for a seamless integration with the Oracle Exadata Database Machine and provides a high-bandwidth low-latency I/O path that generates relatively little CPU overhead.
• One MB Record Sizes.
• Oracle Direct NFS

C: The majority of new features and bug fixes introduced in a system update are backwards-compatible and allow you to roll back to previous updates without issue. These are applied automatically by the storage management software.

D: The configuration backup function enables the administrator to backup the appliance configuration, consisting of system metadata only (such as the network configuration, local users and roles, service settings, and other appliance metadata).

F: To maximize the availability of your data in production, the ZFSSA includes a complete end to-end architecture for data integrity, including redundancies at every level of the stack. Key features include the following:

• Integrated software restart of all system ZFSSA Services

Configuring the Oracle ZFS Storage Appliance for AD Access

(E) In order to create the appropriate authentication objects and permissions, the Oracle ZFS Storage Appliance should be configured to access AD. The DNS service plays a large role in AD and the Oracle ZFS Storage Appliance must therefore be configured to use the Windows DNS Service.

(D) Clock synchronization is also important for correct AD operation. Clock skew between the Oracle ZFS Storage Appliance and the AD Domain Controllers must be less than 15 minutes for a successful AD join. It is highly recommended to install a Network Time Protocol (NTP) service and to configure the Oracle ZFS Storage Appliance and the AD domain controllers to become clients of the service.

Steps:

• Using the browser user interface (BUI) of the Oracle ZFS Storage Appliance, ensure that the DNS configuration refers to the same DNS server as the Active Directory servers. As shown in the following figure, access the DNS Configuration screen by selecting Configuration > Services > DNS.

• Ensure the clocks on the Oracle ZFS Storage Appliance and Windows AD Domain controllers are in synchronization.In the BUI, select Configuration >Services > NTP. Enter the appropriate values for NTP Server(s) address details.

• From the Configuration > Services > Active Directory page, click the Join Domain button as shown in the following figure.

• Enter the details of a Domain Administrator with the authority to allow the Oracle ZFS Storage Appliance to join the AD, as seen in figure 6. Click APPLY to continue

Configuring Storage Using the CLI, Adding Cache Devices to an Existing Pool

• Install the new Readzilla or Logzilla device into the first available slot.
• At the command line, enter:poc:> configuration storage
• Specify the pool you want to add the device to:poc:configuration storage (pool_2)> set pool=pool_2pool = pool_2poc:configuration storage (pool_2)> addA message reminds you to verify that the device is correctly installed. Note that mixing device types and speeds is strongly discouraged.
• Show the device information for the pool:poc:configuration storage (pool_2) verify> showID STATUS ALLOCATION DATA LOG CACHE RPM0 ok custom 0 0 0/4 1.86T1 ok custom 0 0/2 34G 0 150002 ok custom 0 0/2 34G 0 15000
• Specify which disk shelf and the number of Logzillas or Readzillas to use. In the following example, 1-log=1 allocates one Logzilla from the first disk shelf.poc:configuration storage (pool_2) verify> set 1-log=11-log = 1Note: A value of "1-log=2" would allocate two Logzillas from the first disk shelf.This example allocates one Readzilla from the first disk shelf.poc:configuration storage (pool_2) verify> set 1-cache=11-cache = 1
• Enter done.poc:configuration storage (pool_2) verify> done
