Managing your organization's (information) assets.With all the industry buzz around ILM (information lifecycle management Information Lifecycle Management refers to a wide-ranging set of strategies for administering storage systems on computing devices. Specifically, four categories of storage strategies may be considered under the auspices of ILM. ), tiered storage A data storage system made up of two or more types of storage based on their access speed. For example, magnetic disk and tape or magnetic disk and optical disc are widely used in a tiered storage system.

Only by implementing policies, procedures, and technologies to effectively handle information through all four phases can an organization ensure that its critical information assets are treated in a way that storage is secure and recoverable. Likewise, through understanding its "CARD" phases, an organization can reduce its investment in the storage infrastructure supporting the recoverability of all its essential and non-essential information.
Many vendors, industry and end-user groups, and standards organizations A standards organization, also sometimes referred to as a standards body, a standards development organization or SDO (depending on what is being referenced), is any entity whose primary activities are developing, coordinating, promulgating, revising, amending, are currently defining the mindset mind·set or mind-set

Leading the charge is the Data Management Forum of the Storage Networking Industry Association An association of producers and consumers of storage networking products, whose goal is to further storage networking technology and applications. The Storage Networking Industry Association, or SNIA (SNIA (Storage Networking Industry Association, San Francisco, CA, www.snia.org) An organization devoted to the advancement of mission critical storage systems. Founded in 1997, its goal is to determine the standards that must be developed to allow hosts and storage systems to interact via ). This group brings together participants from the end-user community, as well as storage and information management software vendors, and other records management organizations like the Association of Records Managers and Administrators The Association of Records Managers and Administrators (ARMA International) is a not-for-profit professional association for records and information managers and related industry practitioners and vendors.

And once it becomes a widely-accepted standard, experience suggests that many vendors will add their own individual nuances, much as has occurred within open systems technologies. But the need for a standard is undeniable: end-users are demanding it, businesses can't function without it, and the industry can't sustain the lingering confusion any longer.
Even with the adoption of such a standard, however, individual organizations will still need to understand the four basic phases of information metamorphosis as they apply to their own corporate and customer data. Only once the information creation, access, retention, and deletion phases have been outlined, documented, and communicated, and the transition between each phase identified, can an organization choose the appropriate storage technology, software, and operational processes for its short- and long-term information storage needs. Each type of information in each phase has varying service and operating level requirements because of differences in usage patterns. Each also supports different business requirements. These requirements dictate the business- and compliance-driven long-term storage, disaster recovery, and restore requirements, which in turn dictate the appropriate ITIL (Information Technology Infrastructure Library, www.itil.co.uk) One of the more comprehensive as well as non-proprietary and publicly available sets of guidelines for "best practice" IT services management, owned by the British Office of Government Commerce (OGC). best practices and the optimal logical and physical storage structures.
Developing a "CARD" (Creation-Access-Retention-Deletion) Mindset
Creation and Access are usually pretty clear cut; most organizations know (or should know) why information is created and why and by whom it is supposed to be accessed. But, understanding or defining Retention and Deletion requirements can be a Rorschach test Rorschach test: see personality; psychological tests. for many companies, as some regulations leave them up to organizational policy. Some organizations have a "retain forever" policy, while some have stringent destruction requirements. A policy at either end of the spectrum is taxing for a storage or IT administrator, as well as for the legal department and other groups that may need to locate information on demand within a certain time frame.
Clarifying all four phases is best done by starting at the beginning, and understanding all the variables"--the "who, what, where, when, why, and how"--of the creation phase for all information. Understanding these facts is FACTS I Federal Agencies' Centralized Trial-Balance System essential to successfully calculating the value of each type of data and, therefore, its appropriate treatment. Unfortunately, value can't simply be "calculated." However, in order to accurately prioritize pri·or·i·tize

v.intr. each type of information, it is imperative to assign a relative value to it, through careful consideration of the above-mentioned variables.
Accurately prioritizing data also requires the assignment of ownership and accountability. These are usually application-or business-unit based. Generally, when information is dynamic or "fresh", its associated "value" is perceived to be higher than when it becomes static or reference information. Aside from its internal value to the organization, external regulations can impute impute v. 1) to attach to a person responsibility (and therefore financial liability) for acts or injuries to another, because of a particular relationship, such as mother to child, guardian to ward, employer to employee, or business associates. a value of their own. For any piece of information, your organization must decide what fiscal, legal, historical, and administrative requirements it fulfills.
Once the business value of the data has been determined, it is possible to make prudent, strategic decisions about the amount of investment that can and must be made in its handling throughout all four phases. For example, compliance regulations can dictate requirements for performance, recoverability, and number of available copies. Regulatory requirements Regulatory requirements are part of the process of drug discovery and drug development. Regulatory requirements describe what is necessary for a new drug to be approved for marketing in any particular country. , combined with business requirements, can then be translated into policies, procedures, and technologies, the cost of which is weighed against the requirements. The actual cost of information management encompasses many variables, including physical storage, hardware and software management, liability, not to mention the personnel resources involved through all four phases. For every primary byte of data stored, there is a multiplier multiplier
In economics, a numerical coefficient showing the effect of a change in one economic variable on another. One macroeconomic multiplier, the autonomous expenditures multiplier, relates the impact of a change in total national investment on the nation's total attached as a result of multiple "touches" to the information and multiple copies that may exist. At some point this multiplier may become exponential and often unmanageable as a result of replicated copies on disk or tape. Reducing this multiplier is the argument behind ILM.
During the access phase, value, importance, security, encryption The reversible transformation of data from the original (the plaintext) to a difficult-to-interpret format (the ciphertext) as a mechanism for protecting its confidentiality, integrity and sometimes its authenticity. Encryption uses an encryption algorithm and one or more encryption keys. and recoverability requirements most likely will not change. However, it is frequency of access that dictates physical or logical location. During the access period, the performance requirements usually change, which may require a change of platform or location from where the information was first created. But the application will still need to locate the information. This is where ILM fits into tiered storage. The decision point comes to, "At what exact point (time, value or usage) does the information transition from active to inactive or from temporary to permanent or from dynamic to static, and how is that determination made?" The access period can extend well into the retention period, which can be for decades, hence, the question of long-term storage on disk versus tape. The options for storage protocols and applications for information access are becoming more abundant, but also more diverse. As much as the variety of possibilities offers, it complicates storage and information management; hence, the focus on standards. In turn, such technologies are not always easily integrated into the infrastructure. For example, as storage converges more towards the IP network, security and accessibility are becoming even more complicated.
This is one of the more difficult phases that many organizations struggle with. How long must information be kept? In some industry-verticals subject to specific regulatory guidelines, such as healthcare and finance, it's pretty clear. But the onslaught of other "general" corporate regulations, as well as pending national privacy legislation will affect technology and process decisions for the long term. Every user group or application owner is going to feel that their information is "the most important" to the organization until they see the price tag. So who is the final arbiter? Is it legal, finance, or the information-owner? Having the ability to store and find the needle in the haystack is what standards-based storage organizations, and the storage industry, are striving for. Everyone wants the elusive, all-encompassing index/search/find/retrieve engine.
How long an information element must be retained dictates technology decisions (disk, tape, optical, or paper storage?). The operational processes to support retention must be instilled and married to technology. Having a schedule with all information types, locations, owners, and retention periods is prudent. The long-term technology is the other difficult factor, as the technology acquisition and integration curve has sharpened, and the terabyte disk is just around the corner. Will the technology you purchase today work with the software and applications of tomorrow?
Don't hit that delete button just yet. Sometimes, it's a matter of not deleting the information. A large factor in the retention phase that leads into deletion is preventing the destruction of information when legal, or other circumstances dictate. A new word in the IT vocabulary is "spoliation Any erasure, interlineation, or other alteration made to Commercial Paper, such as a check or promissory note, by an individual who is not acting pursuant to the consent of the parties who have an interest in such instrument. ." It is the legal term for the intentional alteration or destruction of a document. So, in trying to determine when you can delete a piece of information, be sure to ask your legal group--and don't give up until you get an answer, because they may someday have to stand up in court and explain why or why not something was deleted. A related question is what determines permanent archive? This eliminates the need for some challenging decisions, but the longer you hold off on the delete button, the higher the cost of retention. So be sure you know what legal, fiduciary and administrative reasons allow deletion?
And when you delete, are you sure that ALL copies of the record have been destroyed on all replicas (tapes, media, personal computers, PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM). )? And can you prevent destruction if required to do so? Stop and ask your organization these questions: Does your organization have a documented records retention schedule that includes the type of record, retention period, location(s), access requirements, and continued security paradigms in place?

Understanding "CARD" Strengthens Information Management Policy
This core of this exercise is that each and every phase of CARD must have an associated policy. In some instances the responsibility or decision point must either be removed from the end-user or automated. Every policy must have a documented procedure, and each transition from phase to phase must be documented and assigned an owner. Even more important is putting in place a communication and training strategy, audit and monitoring abilities, and someone responsible for checking the process to ensure that policy is followed.
