You should inspect the box the StorTrends® 1300 Storage Appliance was shipped in and note if it was damaged in any way. If the server itself shows damage, you should file a damage claim with the carrier who delivered it.
Page 26: Preparing For Setup
Choosing a Setup Location • Leave enough clearance in front of the rack to enable you to open the front door completely (~25 inches). • Leave approximately 30 inches of clearance in the back of the rack to allow for sufficient airflow and ease in servicing.
Page 27: Rack Mounting Considerations
Two pairs of short brackets to be used on the front side of the outer rails are also included. Chapter Two : Chassis Set Up...
Page 28: Installing The Inner Rails
Begin by measuring the distance from the front rail to the rear rail of the rack. Attach a short bracket to the front side of the right outer rail and a long bracket to the rear side of the right outer rail. Adjust both the short and long brackets to the proper distance so that the rail can fit snugly into the rack.
Page 29: Locking Tabs
Locking Tabs Both chassis rails have a locking tab, which serves two functions. The first is to lock the server into place when installed and pushed fully into the rack, which is its normal position. Secondly, these tabs also lock the server in place when fully extended from the rack.
Page 30: Installing The Server Into The Rack
You should now have rails attached to both the chassis and the rack unit. The next step is to install the server into the rack. Do this by lining up the rear of the chassis rails with the front of the rack rails. Slide the chassis rails into the rack rails, keeping the pressure even on both sides (you may have to depress the locking tabs when inserting).
Page 31: Installing The Server Into A Telco Rack
Larger chassis should be positioned to balance the weight between the front and the back. If a bezel is included on your server, remove it. Attach the two front brackets to each side of the chassis, then the two rear brackets positioned with just enough space to accommodate the width of the Telco rack.

Texas Public Information Act How StorTrends Tiered Storage and ILM Works At the core of StorTrends iTX stack is a data collection and trending module that collects and categorizes both instantaneous and historical access patterns that can span years. Storage blocks are also cataloged with respect to their RAID levels, class of disk drives (SAS, SATA and so on) and rotational speed (15K RPM, 10K RPM, 7200 RPM and so on).
Page 218 Having chosen the right block to move out and the appropriate time to do so, the StorTrends iTX stack utilizes a very efficient algorithm to perform the migration. The Data Mover technology (that works by advertisement of blocks) ensures that data blocks are migrated without corruption in the fastest possible time.
Page 219: Stortrends Tiered Storage And Csm (Scaling Within Tiers)
This will result in multiple Logical Drives (LDs) in the same tier and data has to be striped across them. There can also be restrictions given by the RAID card in the number of disk that can be added to one LD (maximum expansion support per LD). Some RAID cards may have restrictions on creating arrays across enclosures.

I/O is expedited because several hard disk drives can be accessed simultaneously. RAID systems improve data storage reliability and fault tolerance compared to single hard disk drive systems. Data loss due to a hard disk drive failure can be prevented by regenerating missing data from the remaining data and parity information stored on other hard disk drives in the volume.
Page 230: Raid Overview
Software supports stripe sizes of 8 KB to 512 KB. For example, in a four hard disk drive system using only disk striping (as in RAID level 0), segment one is written to hard disk drive one, segment two is written to hard disk drive two, and so on.
Page 231: Disk Mirroring
Both hard disk drives contain the same data at all times. Either hard disk drive can act as the operational hard disk drive.
Page 232: Selecting A Raid Level
Your StorTrends 1300 storage appliance should have a RAID controller that supports RAID 0, RAID 1, RAID 5, RAID 10 and RAID 50. Depending on your StorTrends 1300 storage appliance configuration, your RAID controller MAY also support RAID 6 and RAID 60.
Page 233: Raid 0
RAID level. RAID 0 breaks up data into smaller blocks and then writes a block to each hard disk drive in the volume. The size of each block is determined by the stripe size parameter, set during the creation of the RAID set.
Page 234: Raid 1N
This array type provides superior data redundancy because there are three or more copies of the data. It is also useful for creating exact copies of an array for backup purposes. However, this array type is expensive, in both performance and the amount of disk space required to create an array type.
Page 235: Raid 5
If a hard disk drive fails, the StorTrends® iTX Software uses the parity stored on each of the other hard disk drives to recreate all missing information. Use also for office automation and online customer service that requires fault tolerance.

Page 257: Appendix E Replication Overview
The Solution: Remote Replication High Availability with Synchronous Replication Various factors have to be considered while architecting a DR solution. Service Level Agreements (SLA) along with tolerable Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are the key factors influencing the planning.
Page 258: Remote Replication Essentially Comes In Two Flavors
Remote Replication essentially comes in two flavors. Synchronous Replication Here the recovery site moves lockstep with the production site and offers best RPO. But it is very costly to implement. Distance is a challenge for Synchronous Replication. Beyond tens of miles, the delays and latencies incurred renders the solution impractical.
Page 259: Synchronous Replication
StorTrends offers the ultimate in flexibility and performance when it comes to disaster recovery and business continuance. Remote Synchronous Replication is implemented on the target stack. This imposes no burden on the application servers and is transparent to the SAN initiators. Setting up a complete mirror-recovery site requires just a few clicks of the mouse and in seconds the entire production server storage configuration is duplicated on the recovery site storage server.
Page 260: Stortrends Asynchronous Replication
StorTrends servers offer a very innovative and feature-rich periodic replication suite called Snap-Assisted-Replication (SAR). This form of replication is used where Service Level Agreement (SLA) permits the administrator to have a relaxation in Recovery Point Objective (RPO) and Business economics does not permit synchronous replication.
Page 261: Delta Snaps
The snapshots in the secondary are essential to provide recovery points. In the event of a failover, the active volume in the secondary cannot be used as it may have some snapshot data that is NOT fully consistent. On a failover to secondary system, the StorTrends iTX will automatically rollback to the latest available snapshot in the secondary.
Page 262: Snap Assisted Replication Of Nas Volumes
This temporary share configuration will be merged with the original configuration during a Failover. The User database is handled in a different way. If ADS / NIS users are used in the primary system, then administrator is requested to configure the secondary system also with the same ADS / NIS configurations.
Page 263: An Overview Of Journal Assisted Replication (Jar)
An Overview of Journal Assisted Replication (JAR) JAR uses Journaling method by staging the data in a rolling log and is thereby is more tolerant to link speed disparities or communication outages. Every I/O has to be replicated out in the same sequence it arrives at the Production site in order to ensure application consistency.
Page 264: Journal And Journal Files
Once JAR is enabled and is in action, it faithfully replicates every incoming I/O to the recovery site allowing a continuous spectrum of recovery points. However, if there is a big disparity between the incoming and outgoing rates, then the Journal size increases and eventually a situation may arrive when the journal will overflow and the replication cannot proceed.

JAR is preferred over SAR when Recovery Point Objective (RPO) has to be very minimal. JAR also provides another benefit with compare to SAR. In JAR, remote volume can be in-sync with Primary volume. SAR always relies on volume’s snapshot in order to replicate data.

Today there are various implementations of CDP. A vast majority of vendors implement it on the Host that is serving as the File or Application Server. In Host based CDP, there is a filter driver or “Data-Tap” residing in the Host Operating Systems that replicates every I/O on the Production Server to the CDP Server.
Page 317 In a typical environment where an average of 10GB production data is changed or generated per hour, a journal file of 1TB can hold four days worth of continuous chronological data. In addition, with eight levels of scheduled snapshots and up to 2000 snapshots per volume StorTrends can deliver any historic data across a very wide time spectrum.

Signals transported at nearly the speed of light are saddled with delays, resulting in latencies that can no longer be ignored, as is the case with LAN data transfers. These round-trip delays range from a couple of milliseconds for inter-city connections to around 80-100 ms from coast-to-coast, and as much as 250-300 ms for submarine transmissions across the globe.
Page 322: Figure 1: Effect Of Tcp Protocol On Transfer Bandwidth
For example, using a single T1 connection, the maximum achievable rate is 1.55 mbps; for T3 it is 45 mbps; with OC3 it increases to 155 mbps, and with Gigabit Ethernet (GigE) links this maximum reaches the impressive order of Gigabits per second.
Page 323: Figure 2: Stortrends Transfer Profile Vs. Tcp Transfer Profile
Figure 2: StorTrends Transfer Profile vs. TCP Transfer Profile Based on the data above, it is clear that for short distances, where latencies are in the sub-ms range (for example, in LAN environments), the throughput is dictated entirely by the link bandwidth.
Page 324: The Stortrends® Itx Wds Implementation And Transfer Acceleration
As noted earlier, although the performance of the TCP stack can be tweaked, it is a fairly accurate generalization that TCP is more suitable for the LAN environment than it is in long-haul networks.
Page 325: Figure 5:The Delta Snapshot Replication Technology Behind Asynchronous Replication In Stortrends Itx
Like many of its competitors, StorTrends® employs delta-snapshot technology to transfer only the data that has changed between passes in order to reduce the amount of data transported. In addition to this, StorTrends® also employs an intelligent data-dedupe algorithm to filter out some of the previously transmitted data from earlier passes.
Page 326: Figure 6: Deduplication And Wan Transfer Acceleration Management In Stortrends Itx
SQL servers generate random I/Os of 8K blocks, and Exchange servers generate random I/Os of 4K blocks, making it easy to see that even when chunk sized I/Os are replicated, they may carry multiple packets of duplicated data. To remedy this, the deduplication feature in StorTrends iTX utilizes a very I/O-efficient algorithm to detect duplicate data and eliminates them, to further reduce the amount of data transported during asynchronous replication.
Page 327: Additional Wan Assists In Asynchronous Replication With Stortrends
In addition to the optimizations described above, StorTrends® supports the compression and encryption of data before it is released on the WAN, which reduces the net size of data transferred over these more expensive links. StorTrends® supports various compression depths, including an adaptive compression mode where the depth of compression is determined by an analysis of the current and statistical load on the system.
Page 328 The innovative replication stack found in StorTrends iTX offers unprecedented performance for remote replication over wide-area networks. It utilizes an intelligent mix of standards-based transport protocols to overcome the inefficiencies and high latencies of TCP protocols in WANs and provide excellent bandwidth utilization. Additional performance gains are made through data reduction technologies such as compression and data deduplication.

Access Control List. An ACL is a table that tells the system’s operating system the access rights each user has to a directory or file. The directory or file has a security attribute that identifies its access control list. The list has an entry for each system user with access privileges, such as read and write.

Archive The StorTrends® iTX software uses this word to describe the process of backing up data stored on it to a safe place. Asynchronous Replication Asynchronous replication can minimize the performance impact and bandwidth requirements of synchronous replication by forgoing the need to write to the primary and secondary simultaneously.

No snapshot taken at a later time T1 will be replicated, until the prior snapshot taken at time T0 on all volumes are replicated and snapshots for time T0 on all volumes are replicated in the secondary. Similarly, on a failover to secondary, all volumes in the consistency group are rolled back to the same snap group there by maintaining application consistency across all the volumes.

Fibre Channel over TCP/IP. FCIP is a TCP/IP-based tunneling protocol for connecting geographically distributed Fibre Channel SANs transparently to both Fibre Channel and Firewall A set of related programs, located at a network gateway server that protects the resources of a private network from users from other networks. Frame A frame is a single data packet that is transmitted across a network.
Page 340: Group
Group A group is a number of users that are bunched together. Having a group makes it easier to assign a set of rules that are common to a set of users. Common groups can be Accounting, Sales, Marketing, and so on.

The iSCSI protocol increases the capabilities and performance of storage data transmissions. Because of the wide use of IP networks, iSCSI can be used to transmit data over LANs, WANs, or the Internet and can enable location-independent data storage and retrieval.

(initiates) the transfer of information to and from an iSCSI target. iSCSI Name An iSCSI Name is used by the Initiator and Target for locating storage resource and storage resource allocation. The iSCSI Name also is used to identify which initiator has access to which target resource.

2.1 version release. Mirroring the StorTrends® iTX OS is the ability to install the StorTrends® iTX software on two hard disk drives. Basically, if one of the two boot hard disk drives fails, you still maintain the ability to boot to the StorTrends® iTX operating system from the alternate hard disk drive.

Using NIS, each host, client or server in the system has knowledge about the entire system. A user at any host can get access to files or applications on any host in the network with a single user identification and password. It is intended for use on local area networks.

StorTrends® iTX software provides quota support on a per volume basis. This quota can be set for every individual user. If the quota is set to zero, it means the user has unlimited storage access. If the quota is set to a particular size it means the user has only that much amount of storage at his/her access in that volume.
Page 347: Raid 0
RAID level. RAID 0 breaks up data into smaller blocks and then writes a block to each hard disk drive in the volume. The size of each block is determined by the stripe size parameter, set during the creation of the RAID set.
Page 348: Raid 6
A 6-drive array provides two striped three drive RAID 5 sets. Generally, RAID 50 is useful in very large arrays, arrays with 10 or more disks. Like the RAID 1n and RAID 10n array types, RAID 50 can handle multiple disk failures.
Page 349: Raid 60
RAID 60 uses distributed parity, with two independent parity blocks per stripe in each RAID set, and disk striping. A RAID 60 virtual disk can survive the loss of two disks in each of the RAID 6 sets without losing data. It works best with data that requires high reliability, high request rates, high data transfers, and medium-to-large capacity.

As with Copy-on-Write snapshots, systems that implement Redirect-On-Write snapshots also need to maintain tables that contain a map of where old data and new data are stored. However, this mapping needs to be updated and referred to for volume reads in Redirect- on-Write, as opposed to merely for snapshot reads in Copy-on-Write.

Snap Assisted Replication is built on top of the advanced snapshot mechanism provided by the StorTrends iTX 2.1 / 2.5 stacks. In a Snap Assisted Replication environment a primary volume snapshot will be replicated to a volume in a secondary system. Since the snapshot is a frozen image and the snapshot data is sequentially replicated to the remote volume, the remote volume will not be consistent until the entire image is replicated.

SMB can be used over the Internet on top of its TCP/IP protocol or on top of other network protocols such as Internet Packet Exchange (IPX) and NetBEUI.

Page 354: Synchronous Replication
In short, when an I/O is recorded, it is written simultaneously to both the primary and the secondary to ensure parity. The writing of the I/O to the primary is in essence blocked until the secondary is updated. In this way, volumes are protected from failure at the granularity of an I/O, since the primary and secondary sites are always perfectly synchronized with each other, as the name suggests.
Page 355: Volume
It all depends on how you set up your Volumes. The controller treats one or more hard disk drives or unused space on a hard disk drive as a single array. A Volume provides the ability to concatenate storage from various hard disk drives regardless of the size of the space on those hard disk drives.
