Storage systems are no different: creeks are individual disks and river is uplink.

Yes we can do this free of charge. And it'll still force you to take disruptive outages from time to time, if past performance is any indication. And it'll still force you to take disruptive outages from time to time , if past performance is any indication. Patch controllers one-by-one, once in some period of time.

How is it different from updating firmware on hardware controllers you SAN has? Very common situation! Quite often after 3 years it's cheaper to decommission old and buy new unit than to update storage and get renewal for old one still having performance compromised compared to all-new setup. This is exactly what happened with a HDS array we had at [Large well known brand].

A shame really as it was a good system. I would recommend just going with direct attached like the MD These are stack-able and can stack I think 6 shelves. With this you can set up VMotion between 2 - 8 nodes. DFS is OK would not be my first choice. I would rather see regular File Server with good fast backups or snapshots, I have seen DFS replication fail more than once. If you go with Server based storage you would have to use DFS to link it together into a contiguous name space.

The key thing is know your data. This model provides either block and file services, file only, or block only without blades and Control Stations. The block only model uses a 2. The blades have a 2. Each blade has redundant power supplies located in the front of each blade.

This model provides either block and file services, file only, or block only , and uses a SPE form factor. The first slot houses the internal network management switch, which includes a mini-serial port and service LAN port.

Each SP in the enclosure also has two power supply modules. The back of the SPE is shown in Figure Figure 27 provides a close-up view of the back of the SPE. Back of the SPE Figure Front of the SPE The blades in this model use a 2. Front of a DME Figure This model provides either block and file services, file only, or block only and uses a SPE form factor.

This model uses a 2. The blades in this model use a 2. Table 2. The Control Station provides administrative access to the blades; it also monitors the blades and facilitates failover in the event of an blade runtime issue. The Control Station provides network communication to each storage processor.

An optional secondary Control Station is available that acts as a standby unit to provide redundancy for the primary Control Station. This battery power allows the storage processors to de-stage data in-flight to the vault area of the reserved space in the event of a power failure.

Once power is restored to the array, any writes that were de-staged are reconciled and persisted to the target backend disks to ensure that no data is lost. This reserved area consumes GB per disk and provides the landing area for data inflight that is de-staged from the cache in the event of a power failure. Unisphere provides simplicity, flexibility, and automation—all key requirements for optimal storage management. Unisphere is completely web-enabled for remote management of your storage environment.

Unisphere also adds many new features like dashboards, systems dashboard, task-based navigation and online support tools. Figure 42 displays the new system dashboard. You can customize the view-blocks also referred to as panels in the dashboard. Customers require fewer drives and receive the best ROI from those that are configured. With the 7. The storage pools on the left in Figure 43 show the initial storage configuration. This ensures that the appropriate data is housed on the right tier at the right time, which significantly increases efficiency and performance.

You can set polices and schedules to help determine how and when the data is moved. FAST Cache is most appropriate for workloads with a high locality of reference, for example, applications that access a small area of storage with very high frequency, such as database indices and reference tables.

Data deduplication Figure Data deduplication is a file-side feature that includes file-level compression and filelevel single instancing. This asynchronous feature works in the background, scanning for inactive files that may contain duplicate data. If there is more than one instance of a file, it will be single-instanced, along with being compressed. This feature helps increase the storage efficiency of file storage by eliminating redundant data within file systems, thereby reducing storage costs.

It has userconfigurable settings to filter certain files from being processed. It may be turned on or off per file system basis at any time. Thin Provisioning Figure It allows storage administrators to allocate storage on demand. It presents a host with the total amount of storage that has been requested; however, it only allocates storage on the array that is actually being used.

For example, on the file side, a GB file system that has been thin provisioned will be seen by hosts and users as GB. If only 50 percent of the file system is actually in use contains data , only 50 GB will be used on the array. This feature prevents overprovisioning storage that is not used. Thin provisioning increases storage utilization, bringing down the costs associated with maintaining the storage such as power and cooling , and lowering acquisition costs of new storage hardware.

Additional space is assigned 1 GB at a time; however, only 8 KB chunks are reserved as needed. Administrators should understand the growth rate of their pools and file systems to know what percentage is practical and allow enough time to react and address potential oversubscription issues.

This feature is used for file-system-level replication, and provides point-in-time views of the source file systems on the replica file systems. An RPO is a measurement of how much data may be lost before it negatively impacts the business. VNX Replicator also allows bandwidth throttling based on a schedule, e.

This is very useful in environments where VNX Replicator shares network resources with other applications. RecoverPoint integration Figure How RecoverPoint works Unisphere has been designed to accept plug-ins that extend its management capabilities. VNX series arrays are managed with the latest version of Unisphere that includes RecoverPoint integration for replication of block and file data.

Because RecoverPoint uses a single consistency group to provide array-level replication for files and does not provide point-in-time views, it is most appropriate for control LUNs and critical file systems. As an asynchronous process, it provides replication over long distances in the order of hundreds to thousands of miles and has an RPO from 30 minutes to hours.

The synchronous nature of this feature means that for every write to a LUN on the primary storage system, the same write is copied to the secondary storage system before the write acknowledgement is sent to the host. In each case, the RPO is zero seconds, because both copies of data are identical.

VNX Snapshots are point-in-time views of a LUN, which can be made accessible to another host, or be held as a copy for possible restoration. Branching, or snap of a snap, is also supported. There are no restrictions to the number of branches, as long as the entire Snapshot Family is within members. Consistency Groups are also introduced, meaning that several pool LUNs can be combined into a Consistency Group and snapped at the same time.

A memory map keeps track of chunks blocks of data. Before chucks of data are written to the source LUN, they are copied to a reserved area in private space, and the memory map is updated with the new location of these chunks.

This process is referred to as Copy on First Write. This feature allows creation of multiple non-disaster recoverable copies of production data. Checkpoints enable end users to restore their files by integrating with Microsoft Shadow Copy Services. By using our site, you agree to our collection of information through the use of cookies.
