2 What are RAID Premium Features? Premium Features are additional features that can be added to an Intel RAID controller through the application of an add-on enablement key. Implementation of these features is designed to improve specific RAID usage models by adding additional performance, data protection, or other benefit to the targeted usage model. 2

3 Supported Intel RAID Controllers The following Controllers Support addition of Premium Feature Keys: RS2BL080 RS2BL040 RS2MB044 RS2PI008 RS2WG160 RS2SG244 3

4 Course Agenda The course includes the following modules: Module 1: Premium Feature Key Descriptions Module 2: Premium Feature Key Installation and Removal Module 3: Self Encrypting Drive (SED) Configuration and Use Module 4: Snapshot Recovery Configuration and Use Module 5: SSD Cache with Fastpath* Configuration and Use 4

5 Module 1 Premium Feature Key Descriptions A High Level Description of the Benefits of Each Premium Feature 5

6 Snapshot Recovery AXXRPFKSNSH The Snapshot Recovery feature offers a simplified way to recover data and can also provide automatic protection for the boot volume. You can use MegaRAID Recovery to take a snapshot of a volume and to restore a volume or file Snapshot functionality allows users to capture data changes to the volume. If data is deleted accidentally or maliciously, you can restore the data from view or roll back to a snapshot at a previous Point in Time (PiT) You can make up to 8 snapshots of Point in Times for each volume You can either restore files or roll back applications to a previous point in time Snapshot allows recovery of deleted, modified, or corrupted data from disk in minutes Minimizing downtime experienced by users and eliminates the lengthy process of restoring data from tape A Snapshot allows easy recovery of a server s boot volume in case corruption of operating system occurs Allows easy recovery of the boot volume in the case of an errant update or a corrupted or deleted file. NOTE: Snapshot Recovery is not a substitute for a tested backup strategy. Snapshot never makes a complete backup of a volume, only changes to the selected volume are tracked. When a roll back to a snapshot at a previous Point in Time (PiT) is done, you are undoing changes to the volume that caused corruption or a file deletion. 6

7 Full Disk Encryption AXXRPFKDE Full Disk Encryption support allows the RAID controller to manage the encryption keys for Self Encrypting Drives (SED). It enables authentication key management, auto-lock, and instant erase of self-encrypting drives Data going to the drive is encrypted by the drive, data read from the drive is decrypted by the drive. The controller provides the key management and password interface to the drive. Auto-Locks the volumes when powered down Encryption secures data when a drive is misplaced, failed, or stolen Instant Secure Erase deletes encryption keys from the drive before returning leased Drives or when redeploying with the datacenter, making data unreadable. Reduces the risk of data being compromised when drives eventually leave the data center Significantly reduces the cost and time of repurposing or retiring drives 100% Transparent to Storage Systems / End Users Appears the same as traditional non-encrypting drives Operates at full drive speed - No impact to performance Automatically encrypts/ decrypts all data 128Bit encryption, there is no backdoor *Strong enough for the National Security Agency* 7

8 SSD Cache with FastPath* I/O AXXRPFKSSD Two Separate Features resident on the key that are mutually exclusive SSD Cache Uses solid-state drives (SSDs) as additional cache for the RAID controller. Frequently accessed information is stored in SSD cache to allow for rapid access. SSD Cache can support from 1 to 32 SSD in a second level cache pool Data frequently re-read is copied to the cache pool with the benefit of higher SSD throughput and IO response of the SSD drives. Based on LSI* Cachecade Technology, it is sometimes referred to as SSD Cache (SSC). FastPath I/O Accelerates virtual drives made up of all SSDs by streamlining the RAID FW stack, providing up to 150,000 I/O reads per second for small block I/O activity; this is a dramatic increase over solutions that do not use FastPath. Without FastPath enabled, SSD arrays can reach up to 80,000 IOPs. FastPath streamlines the software stack for use with SSDs to optimize throughput with up to150,000 IO operations Per Second 8

9 Module 2 Premium Feature Key Installation and Removal Understand how to install and remove the feature key from an Intel RAID Controller 9

10 Install the Premium Feature Key IMPORTANT: Your Intel RAID Controller must be programmed with the latest Intel RAID Controller firmware to enable Intel RAID Premium Features Minimum requirements for Premium Feature Key usage. The latest FW is available at The feature key is designed to plug onto a Mainstream or Scalable Performance Intel RAID Controller that has a RAID Premium Feature Key connector. The Intel RAID Premium Feature Key must remain attached to the connector in order to enable the premium feature. Entry level controllers do not support the key features. In the figure, the arrow points to the location of the RAID Premium Feature Key connector for the Intel RAID Controller RS2BL080. This is a 2-pin shielded connector The location of Premium Feature Key connector on your Intel RAID Controller may vary Refer to the Intel RAID Controller User Guide for the location of this connector Intel RAID Controller RS2BL080 10

11 Install the Premium Feature Key 1. Carefully remove the Premium Feature Key from its packaging 2. Locate the Premium Feature Key connector on the Intel RAID Controller 3. With the 2-hole edge of the Premium Feature key pointing to the RAID Premium Feature Key 2-pin connector of the RAID controller, push the key onto the connector on the RAID controller 4. Refer to RAID Controller documentation to finish installing the RAID controller and Software User s Guide for PFK configuration details Premium Feature Key Installed 11

12 Install the Premium Feature Key With the Feature Key installed, unless noted specifically, the added feature must be enabled and/or configured using the RAID BIOS Console utility or RAID Web Console 2 utility. For detailed information on enabling and configuring the feature key option, please refer to the Intel RAID Software User s Guide available under your selected controller at Remove the Premium Feature Key Removing the PFK is done by firmly holding the RAID controller on a flat surface, and pulling the Intel RAID Premium Feature Key from the connector Note: Only single PFK installations are allowed (one PFK header per controller). Multiple premium features may be provided on a single key. When the PFK is removed all premium features provided by the key are disabled 12

13 Determining PFK Enablement BIOS Console To determine available features, select Manage Advanced Software Options in the left pane of the main view. Raid Web Console 2 Feature enabled/disabled status in RWC2 Dashboard view. 13

14 Module 3 Self Encrypting Drive (SED) Configuration and Use Understanding The SED Premium Feature Configuration Steps 14

15 Full Disk Encryption - AXXRPFKDE The Full Disk Encryption Premium Feature is offered as an add-on PFK and is also available on Intel RAID controllers with product code that ends in DE (RS2BL080DE and RS2PI008DE) Full Disk Encryption is encrypting data at rest on a hard disk drive. Although several methods can accomplish this, including software and host-based encryption, the Intel implementation relies on Self Encrypting Drive Technology (SED) Self Encrypting Drive Technology incorporates the encryption circuitry directly on the disk drive. SED drives encrypt everything written to the drive and de-crypt everything read from the drive. When the drive is powered down the SED drive is locked and the encryption key within that drive will not encrypt or decrypt data making the drive unreadable to an individual who does not have the correct authorizations. A security-enabled SED drive may be lost or stolen, but it will not expose its data to an unauthorized user Enabling encryption key management on the RAID controller allows the controller to manage the encryption key on the drive SED Auto-Lock functionality is enabled and managed within the RAID controller configuration utilities. Disk Encryption Services are available only for Intel 6Gbs Mainstream and Scalable Performance RAID controllers when the AXXRPFKDE PFK is installed 15

16 Encryption Management FAQs SED functionality affect on disk drive performance The SED has its AES engine built into the electronics, the throughput affect is imperceptibly small (a few millionths of a second). SED drives operate at the same throughput and response time levels as non-sed drives. Incorporation of the SED into the drives allows encryption performance to scale with the number of drives in the system. AES 128 bit implementation Both the NSA and NIST have asserted that AES-128 provides sufficient protection. There are 2^128 = 3.4 x 10^38 possible keys with 128 bits, which is a huge key space. NIST estimates that AES 128 is safe from key-search techniques for at least the next 30 years. The Seagate implementation of AES in drive circuitry has received NIST certification through an independent laboratory, as tested against the FIPS 197 standard. 16

17 Encryption Management FAQs (Cont) There are there no backdoors to the SED drives There is no way to circumvent the security measures provided by the drive. Security best practices dictate that sensitive or critical data should be backed up, as well as critical parameters like Security Keys. SED and non-sed drives can be mixed in the same Volume Non-SED drives cannot be part of an encryption-protected RAID set. SED drives can be used in non-encryption-protected RAID groups. A customer should purchase all SED drives to achieve an encrypted volume. The locking function is configured by selecting the appropriate feature on the RAID management console for those drives and defining a Security Key. SED drives have the same usable capacity as non SED drives The usable capacity of a drive is not reduced with SED 17

18 Encryption Management FAQs (Cont.) Instant secure erase functionality An authorized administrator can remove the on-board encryption key, thereby rendering the encrypted data unreadable. Intel RAID supports this feature on all 6Gbs products, even when a PFK is not present. It is not possible to erase a secure drive that is part of a secure volume group. You must first delete the volume configuration on the drive so that it is marked as Unconfigured. Boot protection for a system with SEDs The server can be configured to pause during the boot sequence for a password. If the appropriate password is not entered in three attempts, the server will still boot but the data on the SEDs will be inaccessible. This protects the data on the SEDs in the event the server is stolen. If the OS boot partition is secured via SED, the server can be configured to pause during the MegaRAID boot sequence for a password. If the appropriate password is not entered in three attempts, the server will not boot 18

19 Managing Self Encrypting drives Three Steps to enable and manage self encrypting drives (graphics on following pages): 1. Verify Encryption Capability after the PFK is installed 2.

29 Module 4 Snapshot Recovery Configuration and Use Understand, configure, and use the Snapshot Recovery premium feature. 29

30 Snapshot Overview The Snapshot feature offers a simplified way to recover lost or corrupted data and provides automatic protection for the boot volume. You can use this feature to take a snapshot of a volume at a Point in Time (PiT) and then later roll back an individual file or a complete volume to that point in time. A Base Volume, or volume containing data, is designated and a repository volume is created to contain changed data. No data is copied at the time the snapshot is created, including the first snapshot. A PiT marker is set in the respository and any data that is changed will first be written to the repository volume. Data is copied on a block basis, not a file basis. So only blocks to be changed are copied to the repository. Note: Snapshot Recovery is not a substitute for a tested backup strategy. When Snapshot Recovery is enabled, a complete copy of the volume is NOT taken, but rather changes to the selected volume are tracked. When a roll back to a snapshot at a previous Point in Time (PiT) is done, you are undoing changes. 30

31 Snapshot Overview (cont) You can use RAID Web Console 2 (RWC2) to create up to eight snapshots of a volume. Creating a snapshot closes the previous snapshot and future changes are then tracked in the new snapshot until it is closed by creating a new snapshot. RWC2 shows the snapshots in chronological order from the oldest to the newest. Each snapshot is a PiT snapshot of the Base virtual drive Once the maximum number of 8 snapshots are created, the Create Snapshot button is disabled until a previous snapshot is deleted. Within RWC2 you can create views of the PiT snapshots. You can search the snapshot view to find and recover data that is not corrupted or missing. Data from view can be copied to the Snapshot Base, or working, volume. 31

32 Snapshot Overview (Cont) The size of the repository should be determined by the amount of data being written and the frequency of snapshots being taken. This is highly application dependent on the behavior of the application and how it manages files. If the repository runs out of space and resizing the repository becomes necessary, it is required to disable the feature and reenable it while re-sizing the repository. One issue with this process is that the existing snapshots are lost when the feature is disabled. Repository virtual drives will be lost if you disable snapshots. A future update will allow to grow the size of the repository dynamically, without losing snapshots. 32

33 Enabling Snapshot Recovery in RAID Web Console 2 1. When you enable Snapshot Recovery, you select two virtual drives -- one as a Snapshot Base and the other as a Snapshot Repository. 2. The base virtual drive contains the data that is stored in the repository virtual drive. 3. To enable the feature, highlight the Virtual drive to be the snapshot based, and go to manage=>virtual drive=>enable MegaRAID recovery; or right click Virtual Drive and select Enable MegaRAID Recovery The Enable MegaRAID Recovery Wizard will then appear 33

34 Enabling Snapshot Recovery in RAID Web Console 2 (cont) 4. On the Enable MegaRAID Recovery Wizard screen, highlight the virtual drive to use as the Snapshot Repository in the Snapshot Repository field. 5. Enter the capacity to use in the Snapshot Repository for changes to the base virtual drive. The available capacity is the largest free block of capacity on the snapshot repository virtual drive. 34

35 Enabling Snapshot Recovery in RAID Web Console 2 6. Choose to create a snapshot schedule or choose to disable the scheduling option. 7. Choose whether to automatically delete the oldest snapshot or to have a snapshot taken on reboot. To enable this option, check the box next to the Take snapshot on reboot field a. If you select this option, a snapshot is taken on boot after every successful shutdown. b. You can use this snapshot of the boot virtual drive to restore the operating system on the virtual drive in case the virtual drive becomes corrupted. CAUTION: Make sure that all data existing on the virtual drive chosen as the snapshot repository is backed up. If there is any existing data on this repository virtual drive, it will be lost after converting to the Snapshot repository. Notes: If you enable Take snapshot on reboot option and the Enable auto deletion of snapshot option (described later), after creating 8 snapshots, the system will automatically delete the oldest snapshot and then create a new one after reboot. 7. Click Finish 35

36 Enabling Snapshot Recovery in RAID Web Console 2 (cont) A confirmation dialog box appears 8. Check the box next to the Confirm field to enable snapshots on the selected virtual drive and then click Yes Snapshot Base This volume will contain the OS or usable data.

45 Module 5 SSD Cache with Fastpath* IO Configuration and Use Understanding SSD Cache and Fastpath Premium Feature Configuration and Use 45

46 SSD Cache with Fastpath IO SSD Cache (also referred to as SSD Cache (SSC) or CacheCade* Technology) uses one or more Solid State Devices (SSD) as additional controller cache, allowing for very large data sets to be copied to that cache to improve performance of data that is re-read. SSD Cache provides performance improvement in READ-intensive applications This solution is ideal for cost sensitive server environments, by offering a highperformance upgrade that requires only a small investment in SSD technology. This solution also reduces the need to invest expensive IT cycles to hand-tune applications running on hard drive-only disk arrays Up to 32 SSDs can be added as a second level cache pool. Fastpath IO is a performance tuned IO Accelerator feature for use with all SSD disk arrays. Raid firmware supporting Solid State Drive configurations is tuned for small, random block-size IO activity Can sustain over 150,000 IO READS Per Second. This feature requires that only SSD drives be connected to the RAID controller. Any Volume created with these SSD drives will then utilized Fastpath IO 46
