Self encrypting drives (SED) What are they? Specific drives with additional security features that encrypt your data at rest and enable instant secure erase for when you decommission your drives.

Why do customers care? Drives move around, between systems, between sites and even get retired. Opportunity to have a data breach is high. Compliance requirements

What sales needs to know They are an upsell Not available for sale online, must contact sales rep to purchase Local key management only

DELL CONFIDENTIAL

Secure Encryption DiskSelf-Encrypting Disk is a security measure Data on drive platters is encrypted and cannot be accurately read without appropriate key (stored in drive circuitry)

-SEDs encrypt everything written to the drive and de-crypt everything read

from the drive

-SED is secured, if the drive is ever powered down or removed from the storage array, the SED becomes locked and the encryption key within that drive will not encrypt or decrypt data making the drive unreadable No performance impact because all encryption is handled by the drive

Management of SED Drives In combination with SEDs, MD Storage Manager supports a full data encryption solution Maintains /controls the key linkage and communications with the SED Provides all the management tools necessary to quickly and simply enable and SEDs

Secure Cost-effective No impact on performance or ease-of-use

Turbo Mode What is it? Provides an incremental boost to performance by opening up additional PCI lanes on the system improving both throughput and I/O Ideal for sequential applications like web streaming or backup Turbo performance key removes firmware limitations

What does it mean to customers? For customers where performance, specifically throughput is critical, turbo will offer a very cost effective solution that rivals FC performance

What sales needs to know This is a premium feature additional charge We are doing 3rd party testing to show the performance improvements over the base model

Turbo vs. Base Performance Performance levels are settable Specific parameters Read vs. write Cache vs. disk

Cache ImprovementWhat has changed? Increased cache size from 512MB to 2GB/controller battery backed Improved cache retention from 72 hours to permanent What it means to the customers? Larger cache improves general overall system performance Permanent retention ensures no lost data will ever occur no matter how long it takes the use to get his system back up and running

Secure Encryption Disk How it WorksDrives can be SED capable or enabled SED capable means drives can use the locking mechanism, but arent currently doing so SED enabled means drives are using the locking mechanism

Once enabled, a drive cannot be returned to the capable state without destroying dataChanging the state resets the encryption key Once enabled, drives stay enabled through power cycles SED enabled drives can be locked or unlocked Locked drives are inaccessible until the lock key is provided Unlocked drives send and receive data as normal Enabled drives are locked at power-on

Unlocked drives stay unlocked until power-down

Unlocking DrivesLocked drives at power-on can be queried for the lock key ID Lock key ID stored on drive Lock key ID changed when lock key changed Lock key and ID stored in NVSRAM One key per storage array Shared across controllers

Key disguised in NVSRAM but not encrypted Lock key used to unlock drives during SOD Lock key may be identified via lock key ID Drives unlocked by sending unlock request with correct lock key All security enabled drives within an array must use the same lock key!

Solid State Drives (SSDs) Use solid state memory (flash) to store data Pliant SAS SSD 149-GB capacity Industry-standard SLC NAND flash memory technology

SSD benefits Increased small-block I/O performance 2x the IOPs per watt, a third of the watts per drive and lower heat dissipation Faster start up (no spin up) and access to data (no rotational latency) Higher reliability with fewer moving parts Ideal for few writes and lots of reads applicationsSSDs should be reserved for high-end applications where the cost can be justified

Near-line SAS Drives Reduces complexity No need for a SATA interposer

Comparably priced to SATA drives Delivers the most capacity for the least money

SAS delivers up to a 38% IOPs per watt improvement over SATA (Seagate datasheet)

Outperforms SATA 25% improvement in sequential reads 140% improvement in sequential writes 15% improvement in random reads

20% improvement in random writes
