This article mainly introduces the example analysis of hp eva4400 storage configuration, which is very detailed and has certain reference value. Friends who are interested must finish it!

As an enterprise-level core data storage system, HP EVA4400 not only has excellent performance but also is easy to configure. With its extensive operating system support and excellent integration with applications such as Microsoft Exchange, Oracle and SAP, EVA4400 has become a reliable choice for enterprise storage solutions with its excellent technology and cost savings.

The HP EVA4400 storage system is based on SAN architecture, so it is generally connected through SAN Switch when connecting to the host. Of course, EVA also supports direct connection to the host FC HBA. When designing the system, we recommend using dual fiber switches and hosts using dual FC HBA cards to ensure the reliability of the system. The following figure shows a schematic diagram of an EVA system connection with a single HSV300 plus a single disk enclosure.

HP EVA4400 consists of two parts of hardware: the HSV300 console and the disk enclosure (scalable).

I. initialization

The HP EVA system needs a PC server to manage EVA. This PC server is called Storage Management Appliance, or SMA for short. Of course, it can also be accessed through the management module of EVA4400 itself. Login method:

Click "Virtual Disks" in the figure, click the "create vdisk" property page on the right side of the content bar to create a VDISK, enter the appropriate parameters, and then click the "finish" button.

You can also create a VDISK Group and then add VDISK to the disk group. If you need to create multiple virtual disks, you can continue to click create.

Supplement: VDISK RAID type, which can be divided into Raid0, Raid1, Raid5 and Raid6

Raid0 does not have any redundancy, any physical disk damage will lead to data loss, so it is not recommended, but the disk utilization of Raid0 can reach 100%.

Raid1 is redundant in mirror mode, and the disk utilization of Raid1 can only reach 50%.

Raid5 is redundant with 4x1 backup, and the disk utilization can only reach 80%.

Like Raid5, Raid6 stripes the logical disk and stores data and check bits, but adds another check bit to each bit of data. In this way, when using Raid6, there will be two hard drives to store check bits, which enhances the fault tolerance function and will inevitably reduce the actual capacity of the hard disk. In the past, the raid level generally allowed only one hard drive to fail, while RAID-6 allowed two hard drives to fail, so RAID-6 requires at least four hard drives. The disk utilization of Raid6 can only reach about 50%.

Note: EVA uses virtual storage technology, and unlike traditional RAID technology, all created VDISK are distributed on all physical disks of Disk, so once VDISK is created, physical disks cannot be unplugged at will to avoid data loss.

After the creation is completed, the figure is as follows:

Click the created virtual disk VDISK001, select the newly created host cyyc, and click present vdisk. This associates the VDISK with the host.

5. Maintain EVA4400

2. Capacity expansion

If the capacity requirement of the HP EVA storage system is not high, you can choose the single controller disk cabinet link method; if the user needs more storage capacity, you can dynamically expand the capacity according to the connection mode shown below. The disk cabinets added in the picture are cascaded and controlled by a HSV300.

Of course, after expanding the capacity of EVA4400, you need to create new disks and associated hosts.
