The first Symmetrix, model 4200, appeared in Then, the In 1995 the Symmetrix Model 3 was announced. The Symmetrix 8000, or Symm5, was the first Symmetrix to introduce a DUAL BUS architecture, providing redundancy in the path to memory. The Symmetrix DMX800 is an incrementally scalable, high-end storage array that features modular disk array enclosures. The Symmetrix Direct Matrix Architecture is storage array technology that employs a matrix of dedicated, serial point-to-point connections instead of traditional buses or switches. The Symmetrix DMX-4 uses redundant Global Memory. The Symmetrix V-Max is the latest model, announced in Symmetrix Foundations - 7

8 Symmetrix DMX-3 and DMX-4 Tiered Storage Platforms Symmetrix DMX-3 & 4: World s Largest High-End Storage Array 96 to 2,400 disks 2 to 12 front directors* DMX-3 and DMX-4 950: High-End Entry Point 32 to 360 disks 2 or 4 Directors *Combinations may be limited or restricted based on configuration DMX disks 2 Memory boards New with DMX-4 4 Gb/s disk adapter pairs Point-to-point back end 4 Gb/s drive enclosures High performance 4 Gb/s 15K FC drives High capacity SATA II disks Support for solid state drives 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 8 The Symmetrix DMX-3 and 4 Series offers flexible scaling to allow independent growth of performance and capacity to meet workload requirements. As an example, a two-da pair system with 32 drives could grow to 360 drives with the addition of another drive bay. Or, if there are high workloads on the initial 240 drives, the most appropriate way to build out the system might be to add one or more DA pairs to support additional workloads, scaling performance upward as capacity increases. The Symmetrix DMX and the Symmetrix DMX-4 models meet a wide range of high-end requirements for scalability, performance, and cost. The most significant improvement is the support for 4 Gigabit back end. The Symmetrix DMX-4 models are ideal for high-end configurations that require performance and the scaling capability to start as small as one disk adapter pair and 96 drives, and grow to a maximum of 4 DA pairs and 2,400 disks.

19 V-Max Architecture Overview Symmetrix V-Max engines Each engine contains 2 integrated directors Each director connects to front end and disks 16 directors with 8 slices each 128 total slices, 256 ports Up to 128 FE ports Up to 1 TB raw memory Over 2 PB usable storage capacity 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 19 The Virtual Matrix Architecture replaces individual, function-specific directors with Symmetrix V- Max Engines, each containing a portion of Global Memory and two directors capable of managing front end, back end, and remote connections simultaneously. As shown, the new architecture enables significant increases in scalability relative to the DMX platform. Scalability has improved in all aspects: front-end connectivity, Global Memory, back-end connectivity, and usable capacity. The increased usable disk capacity is the result of an increase in Global Memory combined with a significant reduction in metadata overhead allowing 2400 devices to be configured with RAID types other than RAID 1 resulting in a dramatic increase in usable capacity. The Virtual Matrix is redundant and dual active and supports all Global Memory references, all messaging, and all management operations including internal discovery and initialization, path management, load balancing, fail over, and fault isolation within the array. The Symmetrix V-Max array is comprised of 1 to 8 V-Max Engines. Each V-Max Engine contains two integrated directors. Each director has two connections to the V-Max Matrix Interface Board Enclosure (MIBE) via the System Interface Board or SIB ports. Since every director has two separate physical paths to every other director via the Virtual Matrix, this is a highly available interconnect with no single point of failure.

Also shown is the raw bandwidth limit for the current generation of each interconnect. Of particular interest given the new distributed memory architecture is the achievable aggregate bandwidth of the Virtual Matrix interconnect. Data arrives on the left front-end I/O modules, then, is sent by the two CPUs to the SIB module which transfers in serial mode to the Virtual matrix for storage. Symmetrix Foundations - 20

The top layer is the Host communication point to the Symmetrix; at the bottom are the actual Symmetrix hardware components, such as memory and directors. EMC s solution enabler APIs are the storage management programming interfaces that provide an access mechanism for managing the Symmetrix, third-party storage, switches, and host storage resources. They enable the creation of storage management applications that do not have to understand the management details of each piece within the total storage environment. Symmetrix V-Max and DMX systems support platform software applications for data migration, replication, integration, and more. Symmetrix Foundations - 24

27 Read Operations Read Hit Read Miss Channel Director Channel Director Global Memory Global Memory Disk Director Disk 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 27 In a Read hit operation, the requested data resides in global memory. The channel director transfers the requested data through the channel interface to the host and updates the Global Memory directory. Since the data is in Global Memory, there are no mechanical delays due to seek and latency. In a read miss operation, the requested data is not in Global Memory and must be retrieved from a disk device. While the channel director creates space in the Global Memory, the disk director reads the data from the disk device. The disk director stores the data in Global Memory and updates the directory table. The channel director then reconnects with the host and transfers the data. Because the data is not in Global Memory, the Symmetrix system must search for data on the disk and then transfer it to Global Memory. Symmetrix Foundations - 27

28 Write Operations Delayed Fast Write Channel Director Fast Write Channel Director No Cache Slots Available in Global Memory Global Memory Global Memory Disk Asynchronous Destage Disk Director Disk 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 28 A fast write occurs when the percentage of modified data in Global Memory is less than the fast write threshold. On a host write command, the channel director places the incoming block(s) directly into Global Memory. For fast write operations, the channel director stores the data in Global Memory and sends a channel end and device end to the host computer. The disk director then asynchronously de-stages the data from Global Memory to the disk device. A delayed fast write occurs only when the fast write threshold has been exceeded. That is, the percentage of Global Memory containing modified data is higher than the fast write threshold. If this situation occurs, the Symmetrix system disconnects the channel directors from the channels. When sufficient Global Memory space is available, the channel directors reconnect to their channels and process the host I/O request as a fast write. Symmetrix Foundations - 28

29 Symmetrix DMX-3 & 4 Redundant Global Memory Data written to Primary region then to Secondary region of the memory board pair All reads are from Primary region Algorithms in Enginuity enable the Directors to take full advantage of all memory cards present when reading and writing Upon Primary or Secondary region board failure, all directors drop the failed board, and switch to non-dual write mode to the good board of the failed memory pair Striping between memory boards is default 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 29 Global Memory board pairs reside next to each other and memory is fully redundant. All writes are initially done to the primary region; writes are then carried out to the secondary region. Primary and secondary regions are distributed across all memory boards so, for example, memory board pairs in slots 0 and 1 have alternating Primary and Secondary regions. Algorithms in Enginuity enable the Directors to take full advantage of all memory cards present when reading and writing. Symmetrix Foundations - 29

All rights reserved. Symmetrix Foundations - 30 A disk is sliced into Hyper or disk slices and protection schemes are then incorporated, creating the Symmetrix volume. Symmetrix logical volumes are defined by using the service processor and SymmWin interface. The Service Readiness Symmetrix Enginuity Configuration website is used to verify an initial Symmetrix configuration and any subsequent changes to the configuration. They use time honored extensive best practices and tools to configure Symmetrix. Symmetrix Foundations - 30

32 Symmetrix Virtual Provisioning Uses Symmetrix TDEV Devices These are cache only devices Virtualization to the host Presented to the host as real device of any supported size Device is virtual in the Symmetrix Reduce wasted disk space Data is kept on common pool only Only what is used is allocated in the common pool Pool is shared by many TDEV devices Support for production and replication Application assigned storage TDEV Devices Allocated Allocated 100 Gig Visible 20 Gig Allocated Save pool 20 Gig Shared Common Storage Pool 2009 EMC Corporation. All rights reserved. Symmetrix Foundations With Enginuity 5773, EMC implemented a Virtual Provisioning capability for Symmetrix DMX systems. Virtual Provisioning presents an application with more capacity than is physically allocated and in some situations may provide a more efficient way of allocating capacity for applications that are somewhat predictable in capacity growth patterns. These virtual devices can reduce wasted disk space because the actual data is kept in a common pool; only what is used is allocated in the common pool and the pool is shared by many TDEV devices. In the example illustrated, the host has a 100 GB Virtual TDEV device, the TDEV device uses no disk space, the Save pool contains the actual data, and only 20 GB is allocated until more space is required. The allocated capability is managed by EMC software. Symmetrix Foundations - 32

33 Symmetrix Logical Volume Formats Open Systems hosts use Fixed Block Architecture (FBA) Each block is a fixed size of 512 bytes Volume size referred to by the number of Cylinders Each Cylinder has 15 tracks On DMX-3, 4, and V-max each track has 128 blocks or 64 KB size Mainframes use Count Key Data (CKD) 57 KB size Count Key Data Data Block 512 Bytes Count field indicates the data record s physical location (cylinder and head) record number, key length, and data length Key field is optional and contains information used by the application Data field is the area which contains the user data V-Max uses new CRC technology in the disk format 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 33 Mainframe systems use Count Key or CKD format, which is a 57 KB track size. Mainframes utilize a Volume Label or Volume Serial which is configured in the Symmetrix BIN file. Data format with open systems use Fixed Block Architecture. On DMX-3, 4, and V-max, each track has 128 blocks or 64 KB size. The V-Max uses a new track CRC method called Block CRC. Symmetrix Foundations - 33

34 Logically Slicing Physical Disk into Hyper Volume Extensions (HVEs) Physical Disk Hyper Volumes slice LUN slice LUN slice LUN 73 GB 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 34 Symmetrix physical disks are split into logical hyper volumes. Hyper volumes are then defined as Symmetrix Logical Volumes and internally labeled with hexadecimal identifiers. A Symmetrix Logical Volume is the disk entity presented to a host via a Symmetrix channel director port. As far as the host is concerned, the Symmetrix Logical Volume is a physical drive. Do not confuse Symmetrix Logical Volumes with host-based logical volumes. Symmetrix Foundations - 34

35 How Symmetrix Logical Volumes Appear to a Host Symmetrix Logical Volumes are viewed by the hosts as disk devices Host is unaware of protection or other Symmetrix attributes Unix hosts access disk through device special files Many hosts use CTD (Controller-Target-Device) format Example /dev/rdsk/c1t1d2 Symmetrix Format Controller Target LUN Other UNIX hosts assign logical names to disk devices Example IBM AIX uses hdisks (/dev/hdisk2) LUN or Hyper volume NT accesses disk devices through a PHYSICALDRIVE name Example: \\.\PHYSICALDRIVE2 Hyper volume 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 35 A host views a Symmetrix Logical Volume in the same manner as it sees any other disk device. The host is unaware of how the volume is configured in the Symmetrix, its protection scheme, or any other special attributes. Hosts assign disk device logical device names that vary depending on the operating system. Symmetrix Foundations - 35

36 Data Protection Mirroring (RAID 1) High performance, availability, and functionality Two hyper mirrors form one Symmetrix Logical Volume located on separate physical drives Parity RAID (not available on DMX-3) 3 +1 (3 data and 1 parity volume) or 7 +1 (7 data and 1 parity volume) RAID 5 striped RAID volumes Data blocks are striped horizontally across the members of the RAID group ( 4 or 8 member group) Parity blocks rotate among the group members RAID 10 mirrored striped meta volumes Dynamic sparing SRDF (Symmetrix Remote Data Facility) Mirror of Symmetrix Logical Volume maintained in a separate Symmetrix 2009 EMC Corporation.

37 Symmetrix RAID 5 and RAID 6 RAID 5 protection on Enginuity 5771 and above Data blocks are striped horizontally across the members of a RAID 5 group Each member owns some data tracks and some parity tracks There is no separate parity volume in a RAID 5 group Instead, parity blocks rotate among the group members Four members per logical volume, RAID 5 (3+1) Eight members per logical volume, RAID 5 (7+1) RAID 6 supported with Enginuity 5772 Allows up to two consecutive drive failures Uses two parity devices horizontal and diagonal parity EMC RAID 6 implementations use either 8 or 16 drives 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 37 RAID 5 protection is available with Enginuity 5771 and above. Data blocks are striped horizontally across the members of a RAID 5 group, each member owns some data tracks and some parity tracks. Four members per logical volume are identified as RAID 5 (3+1) and eight members per logical volume are called RAID 5 (7+1). RAID 6 is supported with Enginuity 5772 and above. RAID 6 allows for up to two consecutive drive failures in the same RAID group or rank. RAID 6 uses two parity devices, horizontal and diagonal parity. Symmetrix Foundations - 37

38 Dynamic Sparing Dynamic Spare Increases protection of all volumes from loss of data Dedicated spare disk(s) protect storage Ensures that the spare copy is identical to the original Resynchronizes a new disk device with the dynamic spare after repair of the defective device is complete Increases data availability of all volumes in use without loss of any data capacity Dynamic sparing is transparent to the host and requires no user intervention 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 38 Dynamic sparing is used as additional protection for volumes already protected by RAID 1 mirroring, parity RAID, RAID 5, or SRDF options. Dynamic sparing provides incremental protection against the failure of a second disk during the time a disk is taken offline and when it is ultimately replaced and resynchronized. Every Symmetrix Logical Volume has four mirror positions. When sparing is necessitated, hyper volumes on the spare disk devices take the next available mirror position for the logical volumes present on the failing volume. Symmetrix Foundations - 38

39 DMX 3 and 4 Mirror Positions Internally each Symmetrix Logical Volume is represented by four mirror positions M1, M2, M3, M4 Mirror positions are actually data structures that point to the physical location of a mirror of the data and status of each track Each mirror position represents a mirror copy of the volume or is unused Symmetrix Logical Volume 04B M1 M2 M3 M EMC Corporation. All rights reserved. Symmetrix Foundations - 39 Within the Symmetrix DMX, each logical volume is represented by four mirror positions: M1, M2, M3, and M4. These mirror positions are actually data structures that point to a physical location of a data mirror and the status of each track of data. Each position either represents a mirror or is unused. For example, an unprotected volume only uses the M1 position to point to the only data copy. A RAID 1 protected volume uses the M1 and M2 positions. If this volume was also protected with SRDF, three mirror positions would be used, and if we add a BCV to this SRDF protected RAID 1 volume, all four mirror positions would be used.

40 RAID Virtual Architecture M1 M2 M3 M4 DMX-4 SRDF1+Mir RAID 1 RAID 1 1 Available Position CSRDF R1+Mir RAID 1 RAID 1 All Positions used M1 M2 M3 M4 V-Max SRDF1+Mir RAID 1 2 Available Positions CSRDF R1+Mir RAID 1 1 Available Position 2009 EMC Corporation. All rights reserved. Symmetrix Foundations - 40 The RAID virtual architecture in Enginuity 5874 changes the mirror positioning handling. In our example of a mirrored device, DMX-4 with two SRDF devices is consuming two mirror positions. In the V-Max, all mirrors use only one position with the SRDF protection occupying a second position. This frees mirror positions for other operations. Virtualizing the RAID architecture is an enabling technology for Enginuity 5874 to implement other features, such as Enhanced Virtual LUN Technology. Symmetrix Foundations - 40
