Terminology In this section, we introduce the terms that are used for the storage system throughout this manual. RAID RAID is the abbreviation of Redundant Array of Independent Disks. There are different RAID levels with different degrees of data protection, data availability, and performance to the host environment. Pools A storage pool is a collection of disk drives. One pool consists of a set of volumes and owns one RAID level attribute. Volumes Each pool can be divided into several volumes. The volumes from one pool have the same RAID level, but may have different volume capacity. LUN A LUN (Logical Unit Number) is a unique identifier for designating an individual or collection of physical or virtual storage devices that execute I/O commands with a host computer, as defined by the SCSI (Small Computer System Interface) standard. iSCSI 4 XEVO Overview © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. Fibre Channel Fibre channel is an extremely fast system interface. It was initially developed for use primarily in the supercomputing field, but has become the standard connection type for storage area networks (SAN) in enterprise storage. SAS Serial-attached SCSI offers advantages over older parallel technologies. The cables are thinner, and the connectors are less bulky. Serial data transfer allows the use of longer cables than parallel data connections. SSD An SSD (Solid-State Drive) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. Thick Provisioning Thick provisioning is allocated upon creation the physical disk drive space and is equal to the user capacity seen by the host server. It also called fat provisioning. Thin Provisioning Thin provisioning is allocated on-demand and can be less than the user capacity seen by the host server. It involves using virtualization technology to give the appearance of having more physical resources than are actually available. Snapshot A volume snapshot is the state of a system at a particular point in time. Local Clone Local clone function has another physical data copy as the original volume. 5 XEVO Overview © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual Remote Replication Remote replication function prevents primary site failure by replicating data to the remote sites. QoS (Quality of Service) QoS has a control mechanism that provides different priorities to ensure that the performance of the data stream reaches a certain level according to the requirements of the application 6 XEVO Overview © 2022 QSAN Technology, Inc.

Discover the Storage System The default setting for the management IP address is DHCP. For users who are going to install at the first time, we provide the XFinder Java utility to search for QSAN products on the network and aid quick access to the login page of the XEVO web interface. 2.1.1. XFinder Utility XFinder utility provides to search QSAN products on LAN. You can discover the management IP addresses of the storage systems via this utility. Please download XFinder utility from the following website. https://www.qsan.com/download.php In addition, XFinder is a java based program. It is also a highly portable utility. To execute this program, JRE (Java Runtime Environment) is required. You can visit the following websites to download and install JRE. http://www.java.com/en/download/ After JRE is installed, run the XFinder.jar program. The AFA storage system in your network will be detected and listed in the table. 7 Getting Started © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual Figure 2-1 XFinder Utility Take an example in Figure 2-1, XFinder discovers two systems in LAN. The default setting of the management port IP address is gotten from the DHCP server, e.g., 192.168.30.242. The default system name is the model name plus the last 6 digits of the serial number, e.g., XF2026-D60000. Double-clicking the selected entry will automatically bring up the browser and display the login page. INFORMATION XFinder utility works in the following network environments: 8 Both the management port of the SAN storage system and the management computer are both on the same subnet domain of the LAN. The LAN works with or without DHCP server. If the LAN doesn’t have a DHCP server, it still can work on zeroconfiguration networking. The management port will be assigned a fix IP address: 169.254.1.234/16. So you can configure the IP address of your management computer to the same subnet domain of the storage system, e.g.: 169.254.1.1/16. Then open a browser and enter http://169.254.1.234 to go into the login page.

Click the Apply button to confirm and proceed. 5.4. Hot Spares The XEVO system sets all free disks as a global spare. If one disk drive of the pool fails or has been removed from any singly redundant RAID, the pool status will change to degraded mode. At the moment, the XEVO system will search the spare disk to execute pool/volume/data rebuild into a healthy RAID drive automatically. 5.5. Disk Roaming Disks can be re-sequenced in the same system or move all member disks in the same pool from system-1 to system-2. This is called disk roaming. The system can execute disk roaming online. Please follow these steps. 1. Select the Storage tab, selects a pool. Click the icon beside the pool name, and then click the Deactivate option. 2. Click the Apply button to apply. The Status changes to Offline. 3. Move all member disks of the pool to another system. 4. In the Storage tab, select the pool. Click the icon beside the pool name, and then click the Activate option. 5. Click the Apply button to apply. The Status changes to Online. Disk roaming has some constraints as described in the following. 1. Check the firmware version of two systems first. It is better for both systems to have the same firmware version or the firmware version of the system-2 is newer. 2. All physical disks of the pool should be moved from system-1 to system-2 together. The configuration of both pool and volume will be kept but LUN configuration will be cleared in order to avoid conflict with the current setting of the system-2. 40 Storage Tab © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual CAUTION Models with XEVO do NOT support disk roaming from models with SANOS. 5.6. SSD Cache SSD cache allows an SSD to function as read cache or write buffer for a HDD volume. In SSD read cache, it is a secondary cache that improves performance by keeping frequently accessed data on SSDs where they are read far more quickly than from the HDD volume. When reads or writes are performed, the data from the HDDs are copied into the SSD cache. Although the data is duplicated to SSD cache pool, it does not matter if the read cache pool is corrupted. In SSD write cache, SSDs are a write buffering storage that improves performance by storing the write data in SSDs temporary where they are write far more quickly than to the HDD volume. And then the write data will be flushed to the HDD volume at the appropriate time. It may take risk of losing data during the period that the write data is stored in SSD cache if the SSD cache pool is corrupted. The write data has not yet written back to the HDD volume. So the read-write cache pool needs data protection to protect the write data. CAUTION Using SSD read-write cache may take risk of losing data if the SSD cache pool is corrupted. User has to monitor the health of the SSD cache pool carefully. For detailed information, please refer to the SSD Cache White Paper from QSAN website. 5.7. Auto Tiering Auto tiering is the automated progression or demotion of data across different tiers (types) of storage devices and media. The movement of data takes place in an automated way with the help of software and is assigned to the ideal storage media according to performance and 41 Storage Tab © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual capacity requirements. It also includes the ability to define rules and policies that dictate if and when data can be moved between the tiers, and in many cases provides the ability to pin data to tiers permanently or for specific periods of time. For detailed information, please refer to the Auto Tiering White Paper from QSAN website. 42 Storage Tab © 2022 QSAN Technology, Inc.

PROTECTION TAB The Protection tab manages the protection groups. It displays the protection group status, configures the protection plan and protection volumes. This chapter describes the details of protection group management operations and examples. 7.1. Protection Features XEVO provides protection group functionality for binding one or some volumes. These volumes can perform data backup services at the same time with some simple settings. In addition to the basic functions of snapshots, local cloning, and remote replication, there are new designs and are described below. 7.1.1. About Snapshot Enable Snapshot Space Automatically A volume snapshot is based on copy-on-write technology. Snapshots require more space to hold differential data. When the schedule function is enabled, all volumes belonging to the protection group will automatically enable snapshot space. The default snapshot space is 10% of the volume capacity. You can also enter the Snapshot Center of the volume and customize it. Recycle Snapshots Snapshot recycle bin can restore or permanently destroy the snapshots. It offers additional protection for backup from accidentally or deliberately deleting of a snapshot. 50 Protection Tab © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual CAUTION Snapshot function can only take the image of data which has been written into the corresponding volume, for the cached data that resides in the server’s cache, that doesn’t yet be flushed into the storage system, it is unable to protect, which means the taken snapshot might consist of inconsistent data / file / boot image, please make sure to take snapshot at the time point when there is no data I/O incoming to the storage system, to prevent the situation as much as possible. Any functionality that base on snapshot function to perform will have this kind of concern, e.g., local clone and remote replication. SUGGESTION It is recommended to use native remote replication function upon the corresponding Operating System to prevent the situation, e.g., vSphere Replication (VR), so that the cached data can be seamlessly replicated to the target site. 7.1.2. About Local Clone It does easily deploy the local clone without doing configurations. In a protection group, select a new and empty target pool, the system will send the configurations of source volumes to the target pool. Then the target pool will generate the corresponding volumes. The limit is that the capacity of the target pool should be larger than the total capacity of all volumes in the protection group. 7.1.3. About Remote Replication QSAN QReplica 3.0 (Remote Replication) provides synchronous and asynchronous replication solutions. With QReplica 3.0 feature, DR (Disaster Recovery) can be achieved with simple and easy orchestration between QSAN platforms. For detailed information, please refer to the QReplica White Paper from QSAN website. 51 Protection Tab © 2022 QSAN Technology, Inc.

All rights reserved. www.qsan.com Official Document XEVO Software Manual APPENDIX Glossary and Acronym List Common Terminology ITEM DESCRIPTION RAID Redundant Array of Independent Disks. There are different RAID levels with different degree of data protection, data availability, and performance to host environment. Disk The Physical Disk belongs to the member disk of one specific RAID group. Pool A collection of removable media. One pool consists of a set of volumes and owns one RAID level attribute. Volume LUN WebUI 93 Each pool could be divided into several volumes. The volumes from one pool have the same RAID level, but may have different volume capacity. Logical Unit Number. A logical unit number (LUN) is a unique identifier which enables it to differentiate among separate devices (each one is a logical unit). Web User Interface. WT Write-Through cache-write policy. A cache technique in which the completion of a write request is not signaled until data is safely stored in non-volatile media. Each data is synchronized in both data cache and accessed physical disks. WB Write-Back cache-write policy. A cache technique in which the Appendix © 2022 QSAN Technology, Inc. All rights reserved. www.qsan.com Official Document XEVO Software Manual completion of a write request is signaled as soon as the data is in cache and actual writing to non-volatile media occurs at a later time. It speeds up system write performance but needs to bear the risk where data may be inconsistent between data cache and the physical disks in one short time interval. RO Set the volume to be Read-Only. GS Global Spare disks. It is shared for rebuilding purpose. If some RAID groups need to use the global spare disks for rebuilding, they could get the spare disks out from the common spare disks pool for such requirement. DG DeGraded mode. Not all of the array’s member disks are functioning, but the array is able to respond to application read and write requests to its virtual disks.
